Poultry keeping in India has emerged as one of the fastest growing sector of Indian agriculture. Consequent to intensification, many nonexistent diseases have emerged and some of the existing has appeared in altered form, viz., very virulent infectious bursal disease (vvIBD), hydropericardium syndrome (HPS), chicken infectious anaemia (CIA), egg-drop syndrome 76 (EDS-76), reoviral infections an...
Vaccination is the most effective means for the prevention of influenza, including pandemic strains. An ideal pandemic influenza vaccine should provide effective protection with the fewest number of doses in the shortest amount of time, and among the greatest proportion of the population. The current manufacturing processes required for embryonated chicken-egg-based influenza vaccines are limit...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
After infection of the upper respiratory tract with foot-and-mouth disease (FMD) virus in immunized cattle, a drop in specific serum-neutralizing antibody activity was observed. Vaccinated cattle with high preexposure serum antibody titers had a precipitous drop for the first 4 days after virus exposure, followed by a rise in titer. This drop was also seen in passively immunized cattle with hig...
congenital varicella syndrome encompasses a broad spectrum of malformations present in children of mothers who developed chickenpox during the fi rst 20 weeks of gestation. we report a case of a monochorionic diamniotic twin pregnancy, with maternal exposure to chickenpox during the thirteenth week of gestation, which produced one symptomatic and one healthy child.
BACKGROUND In Bangladesh, nomadic duck flocks are groups of domestic ducks reared for egg production that are moved to access feeding sites beyond their owners' village boundaries and are housed overnight in portable enclosures in scavenging areas. The objectives of this study were to measure the prevalence of influenza A virus RNA and H5-specific antibodies in nomadic ducks and to characterize...
Pathological studies demonstrated that the salivary gland hypertrophy virus of houseflies (MdSGHV) shuts down reproduction in infected females. The mechanism that underlay the disruption of reproduction functioned on several levels. Females infected at the previtellogenic stage did not produce eggs, reflecting a block in the gonadotropic cycle. Sodium dodecyl sulfate-polyacrylamide gel electrop...
In Vietnam, numerous surveillance programs are conducted to monitor the prevalence of avian influenza (AI) viruses. Three serological methods-the agar-gel immunodiffusion test, hemagglutination inhibition (HI) test, and enzyme-linked immunosorbent assay-are well established for detection of AI virus antibodies in poultry sera. Several recent reports have validated egg yolk as an alternative sou...
