Background & Aims: Duo to clinical use of antibiotics, pseudomonas aeruginosa strains with multiple drugs resistance have significantly increased throughout the world. Betalactamase production is one of the Mechanisms involved in resistance to pseudomonas aeruginosa resulting in many problems in the treatment of infections caused by this bacterium. The aim of this study was molecular analysis o...

Background and Purpose: Candida albicans is the most common Candida species (spp.) isolated from fungal infections. Azole resistance in Candida species has been considerably increased in the last decades. Given the toxicity of the antimicrobial drugs, resistance to antifungal agents, and drug interactions, the identification of new antifungal agents seems essential. In this study, we assessed t...

Backgrounds and Aims: Mastitis is a mammalian disease which is considered important due to its potential economic damages. Trueperella pyogenesis is one of the important opportunistic pathogens of the mammary glands of cattle. This bacterium can produce acute mastitis infection in dairy cattle. In fact, this bacterium has several virulence genes which contribute to its pathogenicity. Therefore,...

Antibiotic resistance occurs in the endogenous flora of exposed population in addition to pathogenic bacteria. This study was conducted to evaluate the distribution of antibiotic resistance genes among 63 isolates of Escherichia coli of Escherichia coli (E. coli) in diarrheic calves and poultry. According to the results, B1 and B2 were the most prevalent phylogroups of E. coli in calves and pou...

background and objectives: septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph s. tritici) is currently the most serious disease of wheat worldwide. this study was established to determine the function of resistant genes of m. graminicola to find out the number of genes corresponding in resistant reaction and also to estimate the genetic parameters of resistance. mater...

conclusions a high prevalence of multiple β-lactamase production was observed among the ampc producers (60%), of which the majority co-produced ampc and mbl. the current study results showed correlation between β-lactamase production and the presence of antibiotic resistance genes in the isolates. results all isolates were multidrug resistant. ampc, esbl and mbl production were observed in 35 (...

results fifty-three (53%) isolates were simultaneously resistant to erythromycin, azithromycin and clarithromycin (cross-resistance); while 8 (8%) isolates had variable macrolide susceptibility pattern. among the s. aureus isolates, the difference in prevalence of resistance to erythromycin between males and females was significant (p = 0.011). the frequency of erma, ermb, ermc, and msra genes ...

Background and Aim: Nosocomial infections caused by gram-negative bacteria are among the most important health-threatening challenges of the current century, particularly following the emergence and spreading of antibiotic-resistance strains. Extended-spectrum beta-lactamase (ESBL), one of the most important antibiotic resistance mechanisms, is spreading worldwide. Surveillance and gathering da...
