...in the genetic nature of circulating FMD virus, samples were collected from suspected outbreaks in Southern Punjab. The virus was primarily detected with RT-PCR with P1/P2 and 1F/1R universal primer pairs directly from field samples including tissues, vesicle and secretion. The direct sequencing and subsequent analysis of amplified PCR products for VP1 gene indicated the circulation of serotype O of FMD in studied areas. Moreover, using serotype-specific prime...

In 2013 sewage contaminated water samples were collected from two sites in Lagos, Nigeria. Samples were concentrated and inoculated into MCF-7 and RD cell lines. Isolates from MCF-7 were passaged in RD and L20B cell lines while isolat...

Numerical method and neutralization test were used to assess the ability of each disinfectant to inactivate the virus. Our results revealed that all the used disinfectants were effective with increasing the contact time more than 15 minutes except with Virkon®S which was...

However, the rapid spread of SAT2 and other exotic FMDV lineages in Libya and Egypt demonstrated the need for a robust surveillance system to detect and respond effectively to exotic infections. Emergence and re-emergence of FMD virus genotypes/lineages has been detected necessitating frequent replacement of the vaccin...

Twelve local isolates of Bangladeshi PPRV were successfully detected from post mortem samples (lymph node, spleen and trachea) of goats and a sheep during the year 2008-2012. The partial N gene of ten isolates and partial F gene of eight isolates were amplified by RT-PCR, and were sequenced. The phylogenetic analysis revealed that PPRVs circulating in Bangladesh belonged to...

On the other hand, the vaccination strategy depending on such vaccines may lead to the emergence of new variants and, consequently, the emergence of a different evolutionary pattern of NDV in Egypt. Therefore, it is necessary to test if genotype II-based vaccines apply unique sel...
