A carAB mutant of avian pathogenic Escherichia coli serogroup O2 is attenuated and effective as a live oral vaccine against colibacillosis in turkeys

Bacterial ghost of avian pathogenic E. coli (APEC) serotype O78:K80 as a homologous vaccine against avian colibacillosis

Avian Colibacillosis is among the major causes of economic loss in the poultry industry worldwide, with a more vivid impact on developing countries. The involvement of several bacteria has made it challenging to develop effective vaccines for this disease, particularly because it is notoriously difficult to make a vaccine that contains all the contributing pathogenic bacteria. Here, we report t...

A review of prophylactic measure against brucellosis in human with a live attenuated vaccine

Pathogenic Avian Influenza Candidates against H5N1 Highly Containing NS1 Truncations as Vaccine Live Attenuated Influenza Viruses

Construction of an iss deleted mutant strain from a native avian pathogenic Escherichia coli O78: K80 and in vitro serum resistance evaluation of mutant

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 ...

Phylogenetic typing and molecular detection of virulence factors of avian pathogenic Escherichia coli isolated from colibacillosis cases in Japanese quail

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 a...
