Distribution of Chloramphenicol in the Bovine Genital Tract and Pharmacokinetic Studies of Florfenicol in Cattle
… selected aspects of the distribution of chloramphenicol (CAP) in the bovine genital tract and to conduct preliminary pharmacologic studies with florfenicol (FLO), a fluorinated analogue of thiamphenicol, in cattle.

Human Estrogen Receptor(alpha) Activity on Estrogen Responsive, Integrated Chloramphenicol Acetyltransferase (Cat) Reporter Constructs in Chinese Hamster Ovary (Cho) Cells
The estrogen receptors endogenous to CHO cells did not induce transcription of chromosomal copies of the more complex 2ERETKCAT promoter. In transient transfections hER$\alpha$ regulated transcription of the three 2ERETKCAT cell lines. We found that an ER mutant containing only AF1 elicited a dose …

Bacteriostatic and bactericidal effects of antibiotics on Bacteroides
… of metronidazole, clindamycin, tetracycline, chloramphenicol, cefoxitin and penicillin were determined against sixteen Bacteroides fragilis strains and six B. thetaiotaomicron strains. Drugs were considered bactericidal when minimal bactericidal concentration (MBC) to minimal inhibitory …

Avaliação do sinergismo entre os componentes da pasta ctz e o citronelol frente ao enterococcus faecalis
… interaction between components of CTZ paste (chloramphenicol, tetracycline, zinc oxide and eugenol) and citronellol phytochemical against Enterococcus faecalis (ATCC 29212). The checkerboard test was performed to verify the interaction between substances, through the Fractional Inhibitory …

The location, expression and regulation of three antibiotic resistance genes in acinetobacter
… antibiotics, including the aminoglycosides and chloramphenicol. Yet very little is known about this resistance at the molecular level. A strain of Acinetobacter baumannii (strain SAK) was isolated from a tracheal aspirate; it is resistant to gentamicin, tobramycin, netilmicin, streptomycin, …

Collateral sensitivity and the evolution of drug resistance in Escherichia coli
… resistant strains showed susceptibility to chloramphenicol. It was therefore expected that growth in sub-MIC concentrations of chloramphenicol would reduce mutation rate to ceftazidime resistance, however, an increase in mutation rate was observed. There are two likely hypotheses, the first …

An assessment of antibiotic resistant bacteria in biosolid used as garden fertilizer
… ampicillin, streptomycin, kanamycin and chloramphenicol. Tetracycline resistant bacteria were isolated on MacConkey's agar supplemented with tetracycline and their resistance to ampicillin, streptomycin, chloramphenicol and kanamycin were also determined. A total of 48 isolates cultivated …

Development of techniques for the recovery and enumeration of two mosquito pathogens
… contained 100 µg/ml of polymyxin with 1.0 µg/ml chloramphenicol (NYPC), and the other contained 500 µg/ml of polymyxin alone. The use of the higher level of polymyxin with chloramphenicol reduced the number of viable B. thuringiensis serovar. israelensis. NYPC was used to recover B. thuringiensis …

Development of genetic systems for Clostridia spp. by utilization of extrachromosomal DNA elements
… pKA201 is 8 kb and codes for resistance to chloramphenicol in E. coli and C. perfringens. Plasmid pAK201 was transformed into E. coli and C. perfringens using electroporation. The transformation frequencies were 10$\sp6$ and 10$\sp4$ transformants/ug DNA in E. coli and C. perfringens.

Assessment of human exposure to toxic elements and veterinary drug residues from seafood consumption in Bangladesh
… mercury) and banned veterinary drug residues (chloramphenicol and nitrofuran metabolites) due to seafood consumption as well as to assess changes in exposure between the years 2010-11 and 2015-16. Also, to evaluate whether the consumption of seafood is a health concern due to presence of these …

Molecular typing of virulence genes in enterotoxigenic Bacillus cereus
… cells were subjected to subinhibitory levels of chloramphenicol as a stressor. B. cereus demonstrated consistently high levels of nheA expression at 15 hours when grown in TSB containing subinhibitory concentration (SIC) chloramphenicol (15.625 mg/ml). Relative levels of nheA expression differed …

A Study of the Coccoid Bodies of Prolinoboborus fasciculus (Aquaspirillum fasciculus)
… rod form to a nonculturable coccoid form. Chloramphenicol did not prevent the conversion. Attempts to obtain variants that would not convert to the coccoid form were unsuccessful. Although the coccoid form fluoresced with acridine orange, agarose gel electrophoresis revealed extensive …

CRABS & ‘CROBES: THE TRIPARTITE RELATIONSHIP OF A HOST, PARASITE, AND THEIR RESPECTIVE MICROBIOMES
… Three broad spectrum antibiotics (ampicillin, chloramphenicol, and gentamicin) and their combinations (total of seven antibiotics and combinations) were tested across four concentrations against all four biological groups. Chloramphenicol, at 2mg/mL, was found to be the most effective …

Toxicological studies in yeast species : production of cytochrome P450 and evaluation of carbon tetrachloride toxicity
… revealed that the compound induced mutations to chloramphenicol resistance at concentrations which were toxic to the cells. Carbon tetrachloride also induced forward mutations in Sch. pombe ade6. Genetic analysis of chloramphenicol resistant mutants indicated non-Mendelian inheritance. The …
