A wild-type strain of Micrococcus radiodurans and its nonpigmented mutant W(1) were tested for sensitivity to 10 antibiotics selected from the standpoint of their mechanism of action. Representatives of groups of antibiotics inhibiting deoxyribonucleic acid (DNA) synthesis, DNA-dependent ribonucleic acid synthesis, protein synthesis, and cell wall synthesis were selected. M. radiodurans and its...

BACKGROUND Nosocomial urinary tract infections (NUTIs) are by definition not present at admission of a patient and are acquired during hospitalisation. The objective of this study was to study the uropathogens and their antibiotic sensitivity patterns in hospital acquired urinary tract infections presenting in a teaching hospital. METHODOLOGY It was a retrospective descriptive study carried o...

Thirty-seven per cent of 126 strains of Staphylococcus aureus, when tested on sheep blood-agar with sensitivity discs containing cephalothin, carbenicillin, oxacillin, penicillin, and cycloserine, produced rings of beta-hemolysis surrounding zones of inhibition of bacterial growth. Each strain capable of producing a ring of beta-hemolysis did so with at least two of the mentioned antibiotics. N...

BACKGROUND Neonatal sepsis is characterised by bacteraemia and clinical symptoms caused by microorganisms and their toxic products. Gram negative bacteria are the commonest causes of neonatal Sepsis. The resistance to the commonly used antibiotics is alarmingly high. The major reason for emerging resistance against antibiotics is that doctors often do not take blood cultures before starting ant...

CONTEXT Head and neck space infections source, age, gender, tooth involved, fascial spaces involved, microbiological study of aerobic flora, and antibiotic susceptibilities. AIMS The aim of the present study is to identify causative aerobic microorganisms responsible for deep fascial spaces of head and neck infections and evaluate the resistance of antibiotics used in the treatment of such. ...
