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 ...

BACKGROUND: Poultry and poultry products are among the major sources of Salmonella infections for humans. Increasing occurrence of antimicrobial resistance among Salmonellae has become a serious public health concern. The detection of extended spectrum b-lactamase (ESBL) producers among Salmonella spp. has increased in recent years. OBJECTIVES: The purpose of this study was to investigate the a...

background: mycotoxins are a group of structurally diverse substances produced by a wide range of moulds. these fungal secondary metabolites, whose presence in feed is unavoidable, can impose hazards to human and animal health. continuous concern about potential effects of mycotoxins in the human diet has led to an increasing interest in researches about fungi and mycotoxin production. the aim ...

Background: Foodborne outbreaks associated with shiga toxin-producing Escherichia coli (STEC) have been well documented worldwide. STECs are major causative agents of gastroenteritis in humans that may be complicated by hemorrhagic colitis (HC), hemolytic uremic syndrome (HUS), and thrombotic thrombocytopenia purpura (TTP). OBJECTIVES: The aim of this study was to investigate the presence of vi...

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...

Avian pathogenic E. coli (APEC) caused avian colibacillosis is mostly common in poultry industry worldwide. APEC virulence factors lead to pathogenesis and the quorum sensing (QS) system actively involved regulation of these factors. Signaling molecules QS are known as autoinducers (AIs). In QS-1, encodes a single LuxR homolog, i.e., SdiA, but does not express LuxI an acyl-homoserine lactone (A...

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...

Avian pathogenic Escherichia coli (APEC) causes avian colibacillosis or and is a major endemic disease of poultry worldwide, including in Indonesia. It characterized by black proventriculus can damage other organs, leading to pericarditis, perihepatitis, water sacculitis, mesenteritis, omphalitis. The APEC strain one the six main sub-pathotypes extraintestinal E. (ExPEC) pathotype. relationship...
