Poor efficacy of the most commonly used anthelmintics in sport horse nematodes in Morocco in relation to resistance. Sport and leisure horses in Morocco are treated with several anthelmintics, organophosphates (dichlorvos), benzimidazoles (mostly thiabendazole) or tetrahydropyrimidines (mostly pyrantel pamoate) against nematodes. We studied three horse stables in Rabat, one in Meknes and one in Bouznika. Two of the Rabat and Bouznika stables had introduced a large number of horses from countries (Argentina or Europe) where resistance to benzimidazoles is frequent, whereas the Meknes stud farm remained without foreign introduction. The number of treatments was not very frequent (twice a year in adult horses) ...

A conservative domain shared by HIV gp120 and EIAV gp90: implications for HIV vaccine design. Both HIV and EIAV belong to the retroviridae family and lentivirus genus. Two variable regions (V3 and V4) of equine infectious anemia virus (EIAV) gp90 and two variable regions (V1 and V2) of HIV gp120 possibly adopt the same topology. We have studied the N-glycosylation properties and B cell linear epitope distribution profile of these two regions. Our results indicated that V3 and V4 of EIAV gp90 are very similar to V1 and V2 of HIV gp120. The differences between EIAV virulent and vaccine strains are mainly located at these two regions. Vaccine strains lose two N-glycosylation sites at thes...

Hendra and Nipah viruses: pathogenesis and therapeutics. Within the past decade a number of new zoonotic paramyxoviruses emerged from flying foxes to cause serious disease outbreaks in man and livestock. Hendra virus was the cause of fatal infections of horses and man in Australia in 1994, 1999 and 2004. Nipah virus caused encephalitis in humans both in Malaysia in 1998/99, following silent spread of the virus in the pig population, and in Bangladesh from 2001 to 2004 probably as a result of direct bat to human transmission and spread within the human population. Hendra and Nipah viruses are highly pathogenic in humans with case fatality rates of 40...
