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 ...

The study was conducted to evaluate the impact of feeding multistrain probiotic on breast muscle characteristics of avian pathogenic Escherichia coli (APEC) infected broilers. Three hundred and thirty six Lohmann MB-202 day-old-chicks were divided to four treatment groups, including CNTRL (chicks receiving basal diet and not infected), APEC (chicks receiving basal diet and infected with APEC), ...

The purpose of this study was to compare avian pathogenic Escherichia coli (APEC) isolates to fecal isolates of apparently healthy poultry (avian fecal E. coli or AFEC) by their possession of various traits in order to ascertain whether APEC and AFEC are distinct and if the APEC strains constitute a distinct pathotype. Four hundred and fifty-one APEC and one hundred and four AFEC isolates were ...
Escherichia coli strains that cause disease outside the intestine are known as extraintestinal pathogenic E. coli (ExPEC) and include human uropathogenic E. coli (UPEC) and avian pathogenic E. coli (APEC). Regardless of host of origin, ExPEC strains share many traits. It has been suggested that these commonalities may enable APEC to cause disease in humans. Here, we begin to test the hypothesis...
Background: The Asia-Pacific Economic Cooperation (APEC) meeting was held from 5 November to 11 November 2014 in Beijing, and comprehensive emission control measures were implemented. The efficiency of these measures on particulate matter-related health impacts and economic cost need to be evaluated. Methods: The influences of emission control measures during APEC on particulate matter were eva...
P or Pap fimbriae of avian pathogenic Escherichia coli (APEC) have previously been shown to be important in the pathogenesis of colibacillosis. However, no study has been done to ascertain the effects of deletion of the genes responsible for P fimbrial biogenesis on APEC's in vitro and/or in vivo characteristics. In the present study, all 11 genes of the pap gene cluster were deleted from APEC ...
Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is a leading cause of economic loss to the poultry industry worldwide. The ability of APEC to cause disease is determined by certain virulence markers, some of which are located on pathogenicity islands (PAls). We recently described one such PAI in an APEC O1:K1 strain (APEC-O1). This PAI, termed PAI I(APEC-O1), carries the genes...
Colibacillosis in chickens caused by avian pathogenic Escherichia coli (APEC) is known to be aggravated preceding infections with infectious bronchitis virus (IBV), Newcastle disease (NDV) and metapneumovirus (aMPV). The mechanism behind these virus-induced predispositions for secondary bacterial poorly understood. Here we set out investigate the immunopathogenesis of enhanced respiratory colib...
