Humans are natural reservoir for Staphylococcus aureus and the common site of colonization for Methicillin resistant Staphylococcus aureus (MRSA) is the anterior nares. MRSA strains may be introduced by colonized hospital personnel and...

Tel.: +2348134136233 The objective of this study was to isolate and determine the antibiotic sensitivity patterns of bacteria isolated from Ogbete abattoir effluent in Enugu State to different classes of antibiotics. Sixty bacterial isolates were obtained from 20 abattoir effluent samples at 4 different points of Ogbete abattoir. The isolated bacteria were identified using standard microbiology...

The activity of three aminoglycosides and six beta-lactam antibiotics on strains of Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureus, and enterococci was studied. The minimal inhibitory concentrations (MICs), the minimal bactericidal concentrations (MBCs), and the minimal antibiotic concentrations (MACs) were determined after 5 h of incub...

Antimicrobial resistance of bacteria is a worldwide problem affecting wild life by living with resistant bacteria in the environment. This study presents a discussion of outside factors environment on microflora of feral pigs (Sus scrofa) from Brazilian Pantanal. Animals had samples collected from six different body sites coming from two separated geographic areas, Nhecolandia and Rio Negro reg...

The in vitro activity of rifampin alone and in combination with oxacillin was determined for 75 Staphylococcus aureus strains (64 susceptible and 11 resistant to oxacillin). Minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) were determined by broth microdilution; antibiotic combinations were evaluated by microdilution checkerboard and time-kill studies. The...

Infections caused by Methicillin-resistant Staphylococcus aureus (MRSA) is a growing problem. Medical students are at risk of getting infected by MRSA during their training due to exposure with infected patients and may be a source of transmission for other patients. Therefore it may be important to know nasal carriage of MRSA among medical students going for clinical posting. This prospective ...

A DNA hybridization method with an enzyme-labeled oligonucleotide probe (mecA-ELONP) was developed to detect the methicillin-resistant gene (mecA) in methicillin-resistant Staphylococcus aureus. For rapid identification, bacterial colonies were transferred from agar plates directly onto nylon membranes. Lysis of cells, denaturation of DNA, and hybridization were performed on the membranes. Thes...
