Background and Objective: Klebsiella pneumoniae is one of the three pathogens that has become a global disease control and treatment problem due to its resistance to common antibiotics. For this reason, it is crucial to study the genes that cause antibiotic resistance in it. Therefore, the aim of this study was to investigate the phenotypic and genotypic frequency of tetracycline resistance in ...

Background: In the present study two hundred milk samples were collected from cows and buffaloes with no history of clinical mastitis in ongoing lactation, Sirohi district Southern Rajasthan. Methods: The pooled sample (collected each quarter) examined for status subclinical by Modified California test Somatic cell count respectively. Positive further investigated isolation identification major...

BENCHMARKS Controlled gene expression is important for elucidating gene functions and developing safer methods of gene therapy (1,2). Historically, early inducible expression systems were mainly based on responses of endogenous elements to exogenous signals or stresses such as heat shock, hormones, or metal ions. However, these systems lacked specificity due to the inducer's pleiotropic effects...

Broiler breeder farms could be a reservoir of Escherichia coli, disseminating antimicrobial resistance and virulence factors. We investigated the E. coli from nine broiler characterised their genes. A total 256 showed high level to tetracycline, nalidixic acid, ampicillin, cephalothin, followed by trimethoprim–sulfamethoxazole chloramphenicol. The trimethoprim–sulfamethoxazole, chloramphenicol ...

The aim of this study was to determine antibiotic resistance genes, phylogenetic groups and anti-microbial resistance patterns of Escherichia coli isolates from fecal samples of healthy pet cats in Kerman city. Ninety E. coli isolates were recovered from obtained rectal swabs. Antibiotic resistance pattern of the isolates against seven selected antibiotic was determined using ...

conclusion these data show that the identified gene encoded tet resistance gene as mfs–type multi-substrate efflux transporter, which contributes to intrinsic resistance on range of structurally unrelated compounds in salmonella species. background tetracyclines (tcs) are a type of broad-spectrum bacteriostatic antibiotics used for treatment of a wide variety of infections. these antibiotics ev...

El estudio tuvo como objetivo la detección de los genes resistencia a antibióticos en aislados Escherichia coli obtenidos cerdos con cuadros diarreicos granjas tecnificadas Lima Metropolitana desde 2017 hasta 2020. Se evaluaron 119 E. coli. Los fueron reactivados para extraer el ADN y detectar principales mayor importancia industria porcina, tales las tetraciclinas (tetA, tetB tetC), sulfonamid...
