...ors involved in the host immunosuppression, although future studies employing in vivo infection models are needed to clearly understand the mechanisms developed by these viruses, in particular PPRV, to interact with the host immune system. A better comprehension of this behaviour could lead the global strategy for the control and eradicaton of PPR, initiated by Food and Agriculture Organization of the United Nations (FAO) and World Organisation for Animal Heal...

...nt patients, decrease in immunosuppression is usually done, however ribavirin therapy has also shown a definitive role. There is upcoming literature on the role of sofosbuvir also in these groups of patients. Since the virus has only one serotype, univalent vaccine can provide protection against all HEV genotypes. Two vaccine candidates have been evaluated in clinical trials. Among these two vaccine candidates, one has been developed by Glaxosmithkline and ano...

T. evansi-infected and non-infected Wester Albino rats immunized against pasteurellosis with two vaccines; one is commercial, and the other is a formalin-killed vaccine (prepared from a local strain), and subsequently challenged virulent P. multocida. The differences in the regulation of IFN-γ, TNF-&alpha...

When the maximum level of ammonia was produced i.e., on day 34, intra-nasal administration of E. coli of strain χ7122 (serotype 078: K80:H9) at pathogenicity amount (9.4 x 105 cfu E. coli per bird) was done and morbidity and mortality rate was also recorded. The significantly minimum ammonia (ppm) was recorded in CRH (30.53±0.77); however, the maximum ammonia (ppm) wa...

A total of 50 tissue samples from backyard chicken flocks presenting suspected symptoms were collected during February 2020 and March 2021 for genetic characterization, followed by phylogentic analysis. A total of 4 isolates were sequenced based on partial VP1 and hyper-variable region of the VP2 genes simultaneously. According to phylogenetic analysis, the study isolates genotype A3B3 were identified as pre...

No sign of immunosuppression in progeny chicks was detected by measuring (NDV) HI antibody titers pre and post lasota vaccination and by vaccination challenge experiment, more over no (CAV) shedding was observed in progeny chicks at early stage of breeding period. In this stage CAV shedding was recorded to be most using CAV VPI PCR assay. These results support the evidence that vaccination of breeders flock with the live attenuated (CAV) va...

In Egypt, the prevalence of IBDV is complicated as multiple strains co-circulating, including classical, variant, and very virulent (vvIBDV). This study aims to investigate the genetic variability and reassortment interactions between co-circulating IBDV strains in Egyptian field, with a particular focus on the VP1(segment B) and VP2 (Segment A) gene sequences.
