CVI988 (Rispens), an avirulent strain of Marek's disease virus, is the most widely used vaccine against Marek's disease. The kinetics of replication of CVI988 was examined in tissues of chickens vaccinated at either 1 day or 14 days of age and sampled regularly up to 28 days post-vaccination. Age at vaccination had no significant effect on the kinetics of CVI988 virus replication. During the cy...
conclusions post-vaccination encephalomyelitis is a very rare side effect of mencevax acwy. introduction post-vaccination encephalomyelitis is an inflammatory disorder of the central nervous system. it is triggered by certain vaccines. the diagnosis of post-vaccination encephalomyelitis depends on the close temporal relationship between vaccination and clinical presentation. case presentation w...
This paper briefly reviews the advantages and limitations of the different vaccines available for use against Newcastle disease in village chickens. Inactivated vaccines give very good immunity without vaccinal reactions and have been widely used, but are relatively expensive and require training to apply. Live vaccines are easy to apply and relatively inexpensive, and give moderately good immu...
گسترش فعالیتهای صنعتی، ازدیاد جمعیت و دخالت بشر در محیط زیست میزان ورود فاضلابهای صنعتی، شهری و کشاورزی را به اکوسیستم های دریایی افزایش داده است. این فاضلابها حاوی آلاینده هایی از قبیل سموم کشاورزی، ازت، فسفر و فلزات سنگین می باشند. فلزات سنگین به علت پایداری و تجزیه ناپذیر بودن، قابلیت ورود به زنجیره های غذایی و تجمع زیستی در آبزیان از مهمترین آلاینده های دریایی محسوب می شوند. راهکارهای بسیار...
Human rhinoviruses (HRVs) and enteroviruses (HEVs) belong to the Enterovirus genus and are the most frequent cause of infection worldwide, but data on their molecular epidemiology in Africa are scarce. To understand HRV and HEV molecular epidemiology in this setting, we enrolled febrile pediatric patients participating in a large prospective cohort assessing the causes of fever in Tanzanian chi...
Lipoprotein LppQ, a predominant 48-kDa antigen, and its corresponding gene, lppQ, were characterized in Mycoplasma mycoides subsp. mycoides SC, the etiological agent of contagious bovine pleuropneumonia. The lppQ gene is specific to M. mycoides subsp. mycoides SC and was found in the type strain and in field strains isolated in Europe, Africa, and Australia, as well as in vaccinal strains. LppQ...
