A total of 318 Escherichia coli isolates obtained from different food-producing animals affected with colibacillosis between 2001 and 2006 were subjected to phylogenetic analysis: 72 bovine isolates, 89 poultry isolates and 157 porcine isolates. Overall, the phylogenetic group A was predominant in isolates from cattle (36/72, 50%) and pigs (101/157, 64.3%) whereas groups A (44/89, 49.4%) and D ...

conclusions more than behalf of the wound isolates were esbl positive, and the presence of blaveb-1 was determined in less than half of these isolates. fortunately, resistance to imipenem and meropenem was low. results the majority of the wound isolates were resistant to augmentin (90%, n = 80) and cefpodoxime (87.6%, n = 78). however, the majority was susceptible to imipenem and meropenem. fif...

Candida kefyr is an increasingly reported pathogen in patients with hematologic malignancies. We studied a series of bloodstream isolates that exhibited reduced echinocandin susceptibilities (RES). Clinical and surveillance isolates were tested for susceptibilities to all three echinocandins, and those isolates displaying RES to one or more echinocandins were selected for molecular and biochemi...

This study was performed to investigate the prevalence of Salmonella spp. in 100 free freshwater common carp samples using the classic culture technique. For the confirmation of the isolates at molecular levels, the invA gene was detected. Serotyping of the isolates was also detected. The presence of invA, class 1 (Cls1) integrons, and integrase (Int1) genes was demonstrated by PCR assay; and th...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

Here, we report the draft genome sequences of six Candida glabrata isolates. The isolates were taken from blood samples from patients after recurrent C. glabrata infection. Two isolates were taken from each of three patients a minimum 3 months apart.

Background & Aims: Organisms producing TEM-β-lactamase are emerging around the world as a source of resistance to β-lactam antibiotics such as three generation cephalosporins. In this study, we used a polymerase chain reaction (PCR) to identify genes TEM for Extended-spectrum β-lactamase (ESBLs) producing clinical isolates of Klebsiella pneumonia from hospitals of Boro...

conclusions molecular epidemiology studies of infectious diseases have been useful when bacterial isolates have been clustered in a period of time and in different geographical regions with variable antibiotic resistance patterns. in spite of high geographical differences and different antibiotic resistant patterns, low genetic diversity among the studied tb isolates may refer to the low rate o...

Tomato black ring virus (TBRV) and beet ringspot (BRSV) are closely related but distinct members of subgroup B the genus Nepovirus. Both viruses have broad host ranges transmitted by seed, pollen, ectoparasitic nematodes. Although 13 TBRV 3 BRSV genome sequences were already available, no attempt has been made to link sequence data from these recent with those historical isolates studied in pre...
