چکیده

Naturally occurring strains of staphylococci which are resistant to chloramphenicol (CM) inactivate this antibiotic. One of the inactivation products of CM showed the chromatographic behavior of 3-acetoxychloramphenicol. Induction of resistance occurred after prior exposure to subinhibitory concentrations of the antibiotic. The resistance of induced populations, as well as CM-inactivation ability, was decreased when they were grown in CM-free medium. The CM-inactivation property was transduced together with CM resistance. Transductional analysis and CM-resistance elimination experiments indicated that CM resistance in naturally occurring strains of staphylococci is mainly accounted for by inactivation of the drug.

Antimicrobial resistance in staphylococci from animals with particular reference to bovine Staphylococcus aureus, porcine Staphylococcus hyicus, and canine Staphylococcus intermedius.

Besides their role as commensals on the skin and mucosal surfaces, staphylococci may be involved in a wide variety of diseases in animals. Staphylococcal infections in animals are mainly treated with antimicrobial agents and as a consequence, staphylococci from animal sources have developed and/or acquired resistance to the respective antimicrobial agents. Resistance statistics obtained from na...

Bacterial Contamination and Antibiotic Resistance of Staphylococcus Aureus Isolated from Automated Teller Machine

Abstract Background and Objective: Automated Teller Machine (ATMs) is likely to be contaminated with various microorganisms specially pathogen germs. This may be due to their exposure to dust and their vast dermal contact with multiple users. This study investigated the bacterial contamination on the keyboard of ATMs and drug resistance of the bacteria isolated from them. Material and M...

Plasmid-mediated transferable chloramphenicol and tetracycline resistance in Salmonella typhi (Vi phage type 25) isolated in Peninsular Malaysia.

In Malaysia, Jegathesan and Khor 20 have reported that four out of 693 strains of S. typhi were resistant to chloramphenicol and other antibiotics. Two of the four strains have been shown to transfer their resistance traits. However, no attempt has been made to demonstrate physically the presence of R plasmids in these strains. In view of this, we chose to study the basis of antibiotic resistan...

Background: Staphylococci as a micro-organism, has the most importance to cause nosocomial infections, particularly in patients with indwelling catheters or other medical devices. Unfortunately 90% of Staphylococci isolated from the nosocomial infections are resistant to methicillin, and methicillin resistance strains are also resistant to a wide range of antimicrobial drugs, therefore detectin...

Antibiotic Resistance of Lactic Acid Bacteria from Canine Faeces

The present study has focused on the occurrence of Enterococcus sp., Lactobacillus sp. and Staphylococcus sp., detected in faeces of healthy dogs, and their resistance to commonly used antibiotics. The average of the total count of enterococci reached 5.9 log10 + 1.2, that of lactobacilli 6.9 log10 + 1.6, and of staphylococci 2.4 log10 + 1.1. Among antibiotics tested, the highest resistance of ...
