Prevalence of Β- Lactamase Producing Staphylococcus Aureus in Slaughtered

Abstract

Fifty liver and lung samples (25 for each) were examend for the presence of Staphylococcus aureus. The rate of S. aureus isolates were 60 and 56% in livers and lungs respectively. Identification of S. aureus isolates were performed by studying, it's cultural characteristics on mannitol salt agar and testing their pathogenicity factors (Coagulase, haemolysis and B-lactmase production), 72.4% of isolates were coagulase positive, 58.6% were βlactamase producer, 62.1% were β-haemolytic and 37.9% were α-haemolytic. There was a difference in the ablity of S. aureus isolates to produce B-lactamase concerning the time of decolourization when iodometric assay was used.

Prevalence of β-lactamase enzymes and molecular detection of the AmpC gene in Pseudomonas aeruginosa isolated from various clinical infections

“…7. Electrophoresis of the of the DNA PCR using AmpC on agarose gel at a concentration of 1.5% M: 100 bp; WO: isolates of wounds (1)(2)(3)(4)(5), BU: isolates of burns (6)(7)(8)(9)(10), UTIs: isolates of urinary tract infections (11)(12)(13)(14), EI: isolates of ear infections (15)(16)(17)(18), RSI: isolates of respiratory infections (19)(20)(21)(22) resistance to commonly used penicillin antibiotics. In response to the resistance of P. aeruginosa, it is imperative to explore alternative solutions, such as using safe nanoparticles, to overcome this challenge effectively.…”
