Colibacillosis is known as a fatal bacterial disease resulting in a high level of commercial loss worldwide. This study amid to elucidate the sequence, genetic characteristics, and phylogeny of the bor gene in Escherichia coli (E. coli) strain c1378 (O78:K80) isolated from avian colibacillosis in Iran and develop a rapid and optimal polymerase chain reaction (PCR) mol...

colibacillosis is of the most common infectious bacterial diseases of poultry.a total of 170 escherichia coli isolates obtained from broiler and layer flocks implicated with colibacillosis between 2011 and 2014 were subjected to phylogenetic analysis. among 150 e. coli isolates from typical lesions of local and systemic colibacillosis, 54 (31.8%), 37 (21.7%), 36 (21.2%) and 43 (25.3%) isolates ...

It is important for the prevention and treatment of colibacillosis to monitor drug resistance in Escherichia coli. To choose effective drugs to prevent and control avian colibacillosis in North China, we investigated the resistance of 164 E. coli isolates (from Beijing, Tianjin, Inner Mongolia, Shanxi, and Hebei regions of China) to commonly used clinical sulfonamide antibiotics using a drug su...

BACKGROUND: Avian Colibacillosis can lead to important economic losses in the poultry industry. Escherichia coli the causative agent of this disease has acquired resistance to different antibiotics, including tetracycline. OBJECTIVES: This study was carried out to detect the distribution of tetracycline Group І efflux genes genes among E.coli isolates from from avian colibacillosis in Iran by P...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

background: colibacillosis, caused by different serotypes of avian pathogenic escherichia coli (apec), is one of the important diseases in poultry industry. the isolate o78 is the most prevalent serotype of apec in iran. one of the apec virulence factors, increased serum survival (iss) gene, is related to serum resistance. the usual form of colibacillosis in avian is extraintestinal, and serum ...

Avian pathogenic Escherichia coli (APEC) is associated with colibacillosis in poultry. Here, we present the first complete sequence of an APEC strain of the O7:HNT serotype and ST73 sequence type, isolated from a broiler with cellulitis. Complete genomes of APEC with distinct genetic backgrounds may be useful for comparative analysis.

Avian pathogenic Escherichia coli (APEC) are responsible for wide ranges of extra-intestinal diseases in poultry including colibacillosis, cellulitis, coligranuloma and yolk sac infection. Numbers of virulence are considered important in the pathogenicity of these diseases. The aims of the present study were phylogenetic typing and virulence genes detection in Escherichia coli </em...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes and phylogenetic gr...
