Colibacillosis, a disease caused by avian pathogenic Escherichia coli (APEC), is one of the main causes of economic losses in the poultry industry worldwide. This study was carried out in order to determine the APEC-associated virulence genes contained by E. coli isolates causing colibacillosis in chickens. A total of 45 E. coli isolates were obtained from the diagnostics and research branch of...

Colibacillosis accounts for significant losses to the poultry industry, and control efforts are hampered by limited understanding of the mechanisms used by avian pathogenic Escherichia coli (APEC) to cause disease. We have found that the presence of the increased serum survival gene (iss) is strongly associated with APEC but not with commensal E. coli, making iss, and the protein it encodes (Is...

Aim: To identify the changes in clinical findings before and after treatment associated with enteric colibacillosis in lambs under different managemental setup. Materials and Methods: Clinical trial was designed on thirty lambs showing the following signs: scanty fecal volume to profuse watery to whitish diarrhoea, varying degree of dehydration, respiration and heart rate, pale mucous membrane ...

Intestinal infection with enterotoxigenic Escherichia coli (ETEC) is an important disease in swine resulting in significant economic losses. Knowledge about the epidemiology, the diagnostic approach and methods of control are of fundamental importance to tackle the disease. The ETEC causing neonatal colibacillosis mostly carry the fimbriae F4 (k88), F5 (k99), F6 (987P) or F41, while the ETEC of...

Colibacillosis results from infection with avian pathogenic Escherichia coli bacteria. Healthy broilers are resistant to inhaled E. coli, but previous infection with vaccine or virulent strains of Infectious Bronchitis Virus (IBV) predisposes birds for severe colibacillosis. The aim of this study was to investigate how IBV affects the course of events upon infection with E. coli. Broilers were ...

Avian colibacillosis is a high-prevalence chicken farm disease caused by avian pathogen-ic Escherichia coli (APEC). It necessary to identify and look up the bacterial activity stave off decline in performance. This study aimed determine pathogenetic of APEC within broiler chickens on duodenum, jejunum, ileum histopathology comparison. The samples were collected from total 40 broilers, obtained ...

Severe enteric colibacillosis, characterized by profuse watery diarrhea, dehydration, apathy, hypothermia, and inability to stand, was produced in seven of eight newborn, colostrum-fed calves from nonvaccinated dams after oral challenge of calves with 10(11) viable cells of Escherichia coli strain B44. Twenty-nine of 32 calves from dams vaccinated with various preparations of E. coli strain B44...

Aim: The present study was designed to study antibiotic resistance profile of E. coli isolates from colibacillosis in layers in and around Pantnagar. Materials and Methods: A total of 20 isolates of E. coli were recovered from 35 cases of colibacillosis in layers during necropsy. Antibiogram was studied via disc diffusion method against 12 antibiotics. Results: Results showed multiple drug resi...

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...
