Prevalence of aerobactin and adhesin genes Prevalence of aerobactin and adhesin genes in in Escherichia coli Escherichia coli isolates from blood of bacteremic severely ill neonatal calves isolates from blood of bacteremic severely ill neonatal calves. Vet. ABSTRACT Escherichia coli isolates are one of the most prevalent bacteria in the blood of bacteremic(More)
AIM The aims of this study were to investigate the phenotypic and genotypic of extended-spectrum β-lactamase (ESBL) and metallo-β-lactamases (MBLs) and determine phylogenetic background E. coli isolates from fecal samples of patients with diarrhea in Kerman, southeast of Iran. BACKGROUND The emergence of ESBLs and MBLs-producing E. coli caused problems in(More)
BACKGROUND AND OBJECTIVES Diarrheagenic Escherichia coli (DEC) strains are a major cause of intestinal syndromes in the developing countries. The aim of this study was to determine the prevalence of enterotoxigenic E. coli (ETEC) and enteroinvasive E. coli (EIEC) in relation to phylogenetic background from patients with diarrhea. MATERIALS AND METHODS A(More)
BACKGROUND Ehrlichiosis is an emerging tick-borne zoonotic disease caused by the family of Anaplasmatacea. Recently, outbreak of human monocytic ehrlichiosis was reported in northern part of Iran. Besides, serological evidence of canine monocytic ehrlichiosis caused by Ehrlichia canis was reported from southeastern of Iran but the epidemiology of this(More)
This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and(More)
BACKGROUND At present, the use of ventilator support is an important part of treatment in ICU patients. However, aside from its well-known advantages, the use of these devices is also associated with complications, the most important of which is pulmonary infection (PI). PI has a high rate of morbidity and mortality. OBJECTIVES This study aimed to(More)
F17 fimbriae are produced by pathogenic Escherichia coli involved in diarrhea and septicemia outbreaks in calves and lambs. These proteins result from the expression of four different clustered genes, namely f17A, f17D, f17C and f17G, encoding a pilin protein, a periplasmic protein, an anchor protein and an adhesin protein, respectively. Several variants of(More)
The objectives of this study were to determine the presence and prevalence of non-O157 shiga toxin-producing Escherichia coli (STEC) isolates from faeces of healthy fat-tailed sheep and detection of phylogenetic background and antibiotic resistance profile of isolates. One hundred ninety-two E. coli isolates were recovered from obtained rectal swabs and(More)
Shiga toxin-producing Escherichia coli (STEC) strains are responsible for outbreaks of human intestinal diseases worldwide. Pigeons are distributed in public areas and are potential reservoirs for pathogenic bacteria. One hundred fifty-four fresh fecal samples were obtained from trapped pigeons in southeast of Iran and were cultured for isolation of E.(More)
Avian cellulitis has been induced by virulent strains of E. coli. The purpose of this study was to determine P (F11) and F1 fimbriae of 90 E. coli isolates of avian cellulitis. Isolates were subjected to six consecutive passages on solid and static broth for expression of fimbriae. Five (5.5%) isolates from O1 serogroup, showed a mannose-resistant(More)
