Virulence gene profiles and intimin subtypes of Shiga toxin-producing Escherichia coli isolated from healthy and diarrhoeic calves
TLDR
The virulence properties of Shiga toxin-producing Escherichia coli (STEC) strains isolated from diarrhoeic and non-diarrhoeic calves were compared and a significant difference was observed in the distribution of Int-θ between two groups.
Occurrence and characterisation of enterohaemorrhagic isolates Escherichia coli from diarrhoeic calves.
TLDR
The results show the possible role of stx1/eae in calf diarrhoea and the particular importance of O26 EHEC in calves and in the transmission of the disease to humans.
Bovine immunodeficiency virus and bovine leukemia virus and their mixed infection in Iranian Holstein cattle.
TLDR
No evidence that infection with one agent predisposed an animal to infection with the other is found, and BIV infection may have a role in decreasing T CD8 counts, but this may depend on the genetics of the cattle and virus strains involved.
Survey of Omp19 immunogenicity against Brucella abortus and Brucella melitensis: influence of nanoparticulation versus traditional immunization
TLDR
Results showed that immunization route has a pivotal role in immune response polarization and protective efficiency of Omp19 antigen, and it was deduced that the higher protection level achieved through oral administration of TMC/Omp19 nanoparticles may be due to the elicited Th17 response.
Cellular immune response of infectious bursal disease and Newcastle disease vaccinations in broilers exposed to monochromatic lights
TLDR
Red light promoted NO (nitrix oxide) production at maximum level in the chickens, while green light suppressed it at minimum level after 37 days, suggesting that green and white lights had strong effects on immunity, especially at the last days of rearing.
Identification of Salmonella isolated from poultry by MPCR technique and evaluation of their hsp groEL gene diversity based on the PCR-RFLP analysis.
TLDR
This study showed that there were differences in the Hae III restriction sites within the groEL gene of strains belonging to serovars S. typhimurium and S. enteritidis but clear discrimination between the serovar of different Salmonella serogroups was not observed.
The genetic architecture of the MHC class II region in British Texel sheep
TLDR
The number and frequency of MHC class II genes in a small flock of Texel sheep is determined to simplify finding disease associations because common haplotypes provide more statistical power but complicate the discrimination of causative mutations from linked marker loci.
