STEFAN SCHWARZ * AND MARISA CARDOSO Institut fur Bakteriologie und Immunologie der Justus Liebig Universitat Giessen, Frankfurterstrasse 107, 6300 Giessen, Federal Republic of Germany Received 21 February 1991 Accepted 9 May 1991 The nucleotide sequence of the chloramphenicol acetyltransferase gene cat ; and its regulatory region, encoded by the plasmid pSCS7 from Staphylococcus aureus, was determined. The structural cat gene encoded a protein of 209 amino acids, which represented one monomer of the enzyme chloramphenicol acetyltransferase CAT ; . Comparisons between the amino acid sequences of the pSCS7-encoded CAT from S. aureus and the previously sequenced CAT variants from S. aureus, Staphylococcus intermedius, Staphylococcus haemolyticus, Bacillus pumilis, Clostridium difficile, Clostridium pefringens, Escherichia coil, Shigeilafl!exneri, and Proteus mirabilis were performed. An alignment of CAT amino acid sequences demonstrated the presence of 34 conserved amino acids among all CAT variants. These conserved residues were considered for their possible roles in the structure and function of CAT. On the basis of the alignment, a phylogenetic tree was constructed. It demonstrated relatively large evolutionary distances between the CAT variants of enteric bacteria, Clostridium, BaciUus, and Staphylococcus species. To carry out AST. Hence, it is important to determine whether the interpreted results obtained by the different methods correlate with one another to ensure that the results obtained in multiple laboratories could be compared without the time delay and added expense of sending the isolates to a reference laboratory. Time is of the essence in cases of widespread disease outbreaks or potential bioterrorism events, where large numbers of isolates would be screened to determine if they are resistant to the first-line drug therapy.16-20 In the current study, we compared the results of four different AST methods agar disk diffusion method, manual broth microdilution, semi-automated broth microdilution, and Vitek ; in S. enterica serovar Heidelberg isolates. Material and Methods Organisms One hundred and five S. enterica serovar Heidelberg isolates n 105 ; were screened in this study.7 Isolates were obtained from turkeys and turkey production facilities. Susceptibility Testing Methods Four different typing methods were used in this study to evaluate the accuracy of the method to correctly determine the antibiotic susceptibility of S. enterica serovar Heidelberg isolates. Each of the methods screened a panel of antimicrobial agents approximately 15 ; . Among the agents tested, eight drugs were common in all four methods and were used for the evaluating the accuracy of the different AST methods. Furthermore, as each method has different measurement endpoints, we collectively interpreted the results based on whether a bacterial strain was susceptible, intermediate-susceptible or resistant to the antimicrobial agent. The eight common drugs evaluated were amikacin, amoxicillin clavulanic acid, ampicillin, chloramphenicol, ciprofloxacin, gentamicin, tetracycline and trimethoprim sulfamethoxazole. Agar disk diffusion testing was carried out on the isolates following standard protocols and the interpretive guidelines from CLSI to determine the susceptibility profiles of the isolates.19 The following antimicrobial agents were tested: amoxicillin clavulanic acid 20 10 g disk ; , ampicillin 10 g disk ; , amikacin 30 g disk ; , ceftiofur 30 g disk ; , ceftriaxone 30 g disk ; , cefoxitin 30 g disk ; , ciprofloxacin 5 g disk ; , chloramphenicol 30 g disk ; , gentamicin 10 g disk ; , kanamycin 30 g disk ; , nalidixic acid 30 g disk ; , streptomycin 10 g disk ; , sulfamethoxazole 300 g disk ; , tetracycline 30 g disk ; , and trimethoprim sulfamethoxazole 1.25 23.75 g disk ; . Following 18 to 20 hours of incubation at 35C, the plates were examined and the zone of inhibition measured for each antibiotic. The manual broth microdilution susceptibility testing was performed using susceptibility plates prepared in the test laboratory. Two-fold serial dilutions of the antimicrobial agents were added to the wells of a 96-well microtiter plate. The following agents were tested dilution ranges ; : amoxicillin clavulanic acid 2 1 g ml to 64 32 g ml.

Control group, a 14-year-old girl with pneumococcal meningitis was admitted comatose after 2 days of high fever. She developed respiratory arrest 6 h later and required assisted ventilation. She died after 7 days, but a CSF sample obtained on hospital day 3 was sterile. Another death occurred in a 12-month-old female with meningitis due to H. influenzae. She had a cardiorespiratory arrest 10 h after admission and died on hospital day 3. The CSF culture remained positive for 38 h after the initiation of treatment despite MBCs for ampicillin and chloramphenicol of 0.06 and 0.125 , ug ml, respectively. A third death occurred in a 12-month-old female with H. influenzae meningitis 20 h after admission; the organism was subsequently lost. The deaths in the ceftriaxone group included a poorly nourished 5-month-old female with a history of fontanelle swelling for 14 days before admission, which had followed trauma to the skull and a broken leg. H. influenzae was cultured from the CSF. The course of this patient was complicated by an enlarging subdural empyema which required needle aspiration and neurosurgical drainage. All CSF and empyema cultures were negative by day 3 of therapy, with ceftriaxone levels as high as 50 , ug ml in the empyema fluid. However, the patient never improved neurologically and died on day 12 of hospitalization. No autopsy was allowed. The other deaths in the ceftriaxone group all occurred in less than 24 h. One 3-month-old female with S. pneumoniae meningitis died of septic shock with deep jaundice, hepatomegaly, and hypotension. CSF cultures were positive at the time of death despite a CSF bactericidal titer of .1: 2, 048 and adequate antibiotic levels in the CSF. The third death was a 7-month-old male who died of a cardiorespiratory arrest 16 h after admission with H. influenzae disease, and the fourth was an 8-month-old female from whom no isolate was identified. Sequelae. The neurological complications consisted of decreased hearing assessed by physical exam ; in two patients in each group. Two of these four patients had an associated otitis media at the onset of meningitis. One patient in the control group developed seizures on day 8 of therapy and generalized motor dysfunction and was found to have diffuse cortical atrophy by computed tomography. A 4-month-old patient with H. influenzae meningitis developed persistent generalized hypotonia. One patient in the ceftriaxone group had not regained full speech and motor ability 1 month after discharge. Fever and meningeal signs. The patients in the control group who could be evaluated were febrile 37.8C ; for 4.47 4.19 days mean standard deviation however, five patients were never febrile. Ceftriaxone patients averaged.

The extract 100 mg ml ; induced proliferation and differentiation in LNCaP cells, but not in PC3 cells, suggesting that the androgen receptor plays a role in mediating the effects of the fruit in LNCaP cells 48 ; . In PC3 cells cotransfected with genes for wild-type androgen receptor and a chloramphenicol acetyltransferase reporter under the control of an androgenresponsive element, the extract 25 mg ml ; inhibited androgen-induced chloramphenicol acetyltransferase transcription by 70% 48 ; . n-Hexane, 90% ethanol and supercritical carbon dioxide extracts of the fruit inhibited 5a-reductase activity in vitro 37, 43, 46, ; . A lipidosterolic extract of the fruit 100 mg ml ; inhibited 5a-reductase activity in the rat ventral prostate by 50%, and reduced conversion of testosterone into dihydrotestosterone in human foreskin fibroblasts by 90%. The conversion of dihydrotestosterone to 5a-androstane-3a-17b-diol by 3a-ketosteroid oxidoreductase was also partially inhibited in cultured human foreskin fibroblasts 43 ; . An n-hexane extract of the fruit inhibited the activity of both 5areductase and 17b-hydroxysteroid dehydrogenase in cultures of epithelial cells IC50 60 and 40 mg ml, respectively ; and fibroblast cells IC50 30 and 200 mg ml, respectively ; obtained from the prostates of patients with BPH 50 ; . One study reported no effect of several lipidosterolic extracts of the fruit on the activity of 5a-reductase from human prostate or on dihydrotestosterone binding to the rat prostatic androgen receptors at concentrations up to 100 mg ml 51 ; . The reasons for these conflicting results are unclear, and may be due to the different methodologies used. Recently, it has been demonstrated that human 5areductase has two isoforms, type 1 and type 2; finasteride, a testosterone 5a-reductase inhibitor has been shown to be a selective inhibitor of the type 2 isoform inhibitory concentration [Ki] 7.3 nmol l ; . Furthermore, an n-hexane extract of the fruit was a non-competitive inhibitor of the type 1 isoform IC50 7.2 mg ml ; and an uncompetitive inhibitor of type 2 IC50 4.9 mg ml ; 52 ; . A 90% ethanol extract of the fruit showed a dose-dependent inhibition of 5areductase activity in the epithelium 29% inhibition ; and stroma 45% inhibition ; of prostate tissue from patients with BPH 52 ; . When the extract was fractionated into saponifiable, non-saponifiable and hydrophilic subfractions, only the saponifiable subfraction consisting mainly of lauric, oleic, myristic and palmitic acids ; was active. Of these fatty acids, lauric acid was the most active: it inhibited epithelial and stromal 5a-reductase activity by 51% and 42%, respectively. The inhibition by lauric acid was noncompetitive and dosedependent up to a concentration of 0.2 mmol l. The nonsaponifiable fraction, consisting mainly of phytosterols, was weakly active, while the hydrophilic subfractions, containing carbohydrates, amino acids and polysaccharides, were inactive 53 ; . A supercritical extract of the fruit inhibited 5a-reductase activity in homogenates of cultured human foreskin fibroblasts IC50 0.025 mg ml ; 46 ; . One study compared testosterone metabolism in primary cultures of epithelial cells and fibroblasts obtained from the prostates of patients with BPH and prostate cancer. In all cultures, androst-4-ene-3, 12-dione, formed by the oxidation of testosterone by 17b-hydroxysteroid dehydrogenase, accounted for 80% 290.

In 0.25 M ammonium sulfate the chromatin is removed, while most of the nuclear shrinkage occurs later in 2 M NaC1. This is probably more gentle mechanically and should give better preservation of nuclear core filament morphology. The spatial distribution of the core filaments is denser than that of the thick matrix fibers from which they derive. The thick fibers of the complete matrix are distributed nonuniformly throughout the nuclear interior with extensive empty spaces Fig. 1 a ; . contrast, the core filaments Figs. 1 b, 2, a and b, and 5 ; fill the nuclear interior more uniformly. Much of this difference is probably due to nuclear shrinkage. As discussed above, the core filaments fill a nuclear volume which is only half that of the complete nuclear matrix. Further, some images suggest that the thick matrix fibers may not be organized around single core filaments but appear to bundle several together. If this model is correct, then several core filaments are clustered in each thick filament. The discovery of RNA-containing core filaments in the nuclear interior has given a new perspective to the work of Lothstein et al. 1985 ; who studied a 43S RNase A resistant nuclear particle generated by nuclease treatment of hnRNPs which had been released by sonication. This RNA-containing particle polymerized into 18-20-nm filaments under conditions of low ionic strength. The filaments had a visible helical repeat of 60 nm. These filaments, polymerized in vitro, have a different appearance from the core filaments of the nuclear matrix which have a smaller diameter and lack a helical repeat. Nevertheless, it is interesting to speculate that both nuclear core filaments and the in vitro polymerized filaments of Lothstein et al. 1985 ; may be assembled by related interactions between RNA and the hnRNP proteins A2, B1, and B2. The low ionic strength in our core filament extraction procedure could be omitted without changing the distribution of nuclear core filaments. Thus, we are satisfied that the core filaments were not generated during the extraction by a low ionic strength polymerization of hnRNP fragments. It may be, however, that the in vitro generated filaments may hold a clue to core filament composition. While it is impossible to completely eliminate the possibility that the core filaments are generated during the extraction procedure, our confidence in their existence is strengthened by the observation of similar filaments in cells which have not been exposed to nuclease digestions, low ionic strength incubations, or high salt extractions. Previous reports from this laboratory have discussed nuclear filaments that become uncovered during mitosis and that remain associated with chromosomes. These nuclear filaments have a morphology similar to the core filaments described here. The filaments first become visible as the chromatin condenses in early prophase Capco and Penman, 1983 ; . The uncovered filaments remain attached to the chromosomes throughout mitosis Capco and Penman, 1903; Wagner et al., 1986 ; . We have also seen nuclear filaments in adenovirus-infected HeLa cells Zhai et al., 1987 ; as chromatin retracts, leaving filaments uncovered. At later stages of adenovirus infection these filaments are decorated with adenovirus nucleocapsids. The mitotic and adenovirus infected cells provide only occasional glimpses of nuclear filaments and the relationship of those to the much more extensive network of nuclear matrix core filaments discussed here is unclear. Nuclear filaments have also been reported by Jackson and Cook 1988 ; who use a very different procedure to reveal and biaxin.

Chloramphenicol plasmid growth RESULTS Molecular cloning of the cat gene from plasmid pUB307: : Tn2424. Meyer et al. 29 ; have shown from restriction mapping data that the amikacin and chloramphenicol resistance genes of Tn2424 are part of a 4.5-kb segment of DNA which is inserted between the streptomycin and sulfonamide resistance genes. The amikacin resistance gene is located close to the streptomycin resistance gene, while the chloramphenicol resistance gene is close to the sulfonamide. 199 moraxella catarrhalis -induced purulent otitis media in the rat middle ear and omnicef. Identification and isolation of the DNA fragments of the P. mirabilis chromosome carrying the cat gene was achieved by first using the type I cat gene isolated from pIC025 ; to probe various restriction endonuclease digests of chromosomal DNA from P. mirabilis. A PstI digest yielded a single band on hybridization data not shown ; , indicating that this fragment was likely to contain the entire P. mirabilis cat gene. PstI-digested chromosomal DNA samples prepared from P. mirabilis in both the CAT' and CAT- states ; were separately ligated with pAT153 which had been cut by PstI and treated with alkaline phosphatase. After transformation, the CAT-containing cells, which were likely to harbor recombinant plasmids selected on 10 , ug chloramphenicol per ml ; , were then screened 7 ; for insert DNA with positive results in each case for an insert of approximately 8.5 kilobases kb ; . Plasmids from one each of the resulting transformants designated pIC100 for the recombinant produced from DNA in the CAT' state and pIC101 for the recombinant produced from DNA in the CAT- state ; were used for large-scale plasmid preparations. Identification and localization of the cat genes in plasmids pIC100 and pIC101. The synthetic 20-mer cat active site consensus probe was used to locate the cat gene within the.

Chloramphenicol otic contraindications A novel type of mutation to chloramphenicol resistance occurs in many strains of the Proteus-ProvidenciaMorganella group which do not appear to harbor plasmids. Proteus mirabilis PM13 has been the subject of detailed studies of the phenomenon 8 ; . Spontaneous chloramphenicol-resistant CAT + ; mutants were isolated at a frequency of lo-4 to 10-5 per cell per generation by selection on complex agar medium containing chloramphenicol 8 ; . The appearance of the resistance phenotype is associated with 1, 000-fold-increased expression of a chloramphenicol acetyltransferase gene cat ; , and there is no coincident increase in the level of resistance to any other antibiotic. During subsequent growth in the absence of chloramphenicol, the phenotype reverts within 150 generations to one of chloramphenicol sensitivity and low-level cat expression. The gene responsible for resistance cat ; has been cloned and shown by Southern blot hybridization to be present at near unit copy in cells of strain PM13, regardless of whether the DNA source was chloramphenicol resistant or not 8 ; . Neither cat amplification nor gene rearrangement within the 8.5 kilobases of cloned DNA ; have been detected; it was proposed that i ; the enhancement of resistance may be a consequence of a trans-acting effector operating at the level of transcription, and ii ; the putative effector is itself controlled by a genetic rearrangement at a locus removed from the site of cat. We present data here which are compatible with a model involving transcriptional control of the cat gene to produce the enhanced chloramphenicol resistance phenotype. Nucleotide sequence comparison of the P. mirabilis cat with the type I Tn9 ; cat variant has shown a high degree of sequence conservation between both structural genes, but little or no evidence of homology in the flanking regions. A model is proposed for the regulation of P. mirabilis cat based on previous expression studies 8 ; and an unanticipated sequence homology with the 5' flanking regions of the Salmonella typhimurium phase variation genes Hi and H2.

From 8 Brazilian states.A total of 2, 085 clinical isolates consecutively collected between December 1995 and March 1996 were susceptibility tested using the Etest and following the NCCLS procedures. Meropenem inhibited more than 90 percent of isolates of Enterobacteriaceae at 0.5g ml, except for Citrobacter sp. 1g ml ; . Generally, meropenem was slightly more active than imipenem against Gramnegative organisms and its spectrum of antimicrobial activity was broader than those of all other drugs tested. Against Pseudomonas aeruginosa, meropenem MIC50, 0.38g ml ; was approximately 8fold more active than imipenem MIN 50, 3g ml ; . Imipenem was twoto eightfold more active than meropenem against some Grampositive specees oxacillin, including Enterococcus faecalis MIC 50 of 0.75g ml and 2g ml respectively ; , oxacillinsusceptible Staphylococcus aureus MIC 50 of 0.47g ml and 0.094g ml ; , oxacillinsusceptible Staphylococcus epidermidis MIC 50 of 0.064g ml and 0.5mg ml ; .Against Streptococcus sp. meropenem was slightly more active than imipenem MIC 50, 0.016g ml ; . The results of this study may be used to guide empiric therapy in Brazil and indicates that meropenem may have an important role in the treatment of infections caused by multiresistant strains of bacteria. AU . Gallardo F. et al. Campylobacter jejuni as a cause of traveler's diarrhea: clinical features and antimicrobial susceptibility. J Travel Med. 1998; 5 1 ; : 236.p Abstract: Traveler's diarrhea is the most common health problem of international travelers. Although enterotoxigenic Escherichia coli seems to be the most frequent cause of traveler's diarrhea, many other microorganisms, such as Campylobacter jejuni, may cause this infectious disease. Campylobacter jejuni is recognized as a leading cause of enteritis in humans both in developing and in developed countries. However, a few reports on the incidence and antimicrobial resistance of Campylobacter spp. as a cause of traveler's diarrhea have been published.The limited data on the treatment of C. jejuni infections suggest that ciprofloxacin may shorten the duration of symptoms. However, treatment failure associated with the emergence of quinolone-resistant strains of C. jejuni has been documented.The purpose of this study was to determine the prevalence of C. jejuni associated with traveler's diarrhea and to analyze the geographic distribution as well as the clinical features and susceptibility to antibiotics. Gallardo F. et al. Increase in incidence of resistance to ampicillin, chloramphenicol and trimethoprim in clinical isolates of Salmonella serotype Typhimurium with investigation of molecular epidemiology and mechanisms of resistance. J Med Microbiol. 1999; 48 4 ; : 367-74.p Abstract: Antimicrobial resistance patterns of Salmonella serotype Typhimurium isolates obtained during the period 1987-1994 were examined and the molecular epidemiology and the mechanisms of resistance to ampicillin, chloramphenicol and trimethoprim were investigated in 24 strains isolated during 1994. Resistance to ampicillin increased from 18% to 78%, to chloramphenicol from 15% to 78%, to tetracycline from 53% to 89% and to co-trimoxazole from 3% to 37%, whereas resistance to norfloxacin remained at 0%. Of Salmonella serotype Typhimurium strains isolated during 1994, all ampicillin-resistant strains had an MIC 256 mg L, except one strain in which the MIC was 64 mg L.Twelve strains 52% ; had a TEM-type beta-lactamase, nine 39% ; a CARB-type beta-lactamase and two strains 8% ; had an OXA-type beta-lactamase. Chlorapmhenicol acetyltransferase activity was detected in only nine 47% ; of 19 chloramphenicol resistant strains, whereas all eight trimethoprim-resistant strains produced a dihydrofolate reductase type Ia enzyme.Three different epidemiological groups were defined by either low-frequency restriction analysis of chromosomal DNA and pulsed-field gel electrophoresis or repetitive extragenic palindromic-PCR.The latter technique provided an alternative, rapid and powerful genotyping method for S. Typhimurium. Although quinolones provide a good therapeutic alternative, the multiresistance of S. Typhimurium is of public health concern and it is important to continue surveillance of resistance levels and their mechanisms.
