An anthelmintic programme employed by the Society for the Protection of Animals Abroad (SPANA) in Morocco was assessed by obtaining faecal egg counts and conditions scores for 158 working equines (donkeys, mules and horses) from souks (markets) routinely visited by the charity and compared with a souk not previously visited. Results showed the current programme to be ineffective in reducing the...

Trypanosoma evansi, the agent of surra, is a salivarian trypanosome, originating from Africa. Surra is a major disease in camels, equines and dogs, in which it can often be fatal in the absence of treatment. Animals exhibit nonspecific clinical signs (anaemia, loss of weight and abortion). In the present survey, a blood sample was collected in Sousse (Central Tunisia) from a dog that presented ...

In Brazil, A. cajennense is the main vector of Rickettsia rickettsii, the etiological agent of «Rocky Mountain Spotted Fever». Besides the intense blood exploitation, the parasitism can affect the animal production capacity and usually determine leather depreciation, leading to secondary infections and myiasis. Although the adult stages have the equines as their preferable hosts, some authors [...

After the 1999 outbreak of West Nile (WN) encephalitis in New York horses, a case definition was developed that specified the clinical signs, coupled with laboratory test results, required to classify cases of WN encephalitis in equines as either probable or confirmed. In 2000, 60 horses from seven states met the criteria for a confirmed case. The cumulative experience from clinical observation...

Serum samples collected from 167 equines of 12 districts in Albania were tested for West Nile virus-specific antibodies by enzyme-linked immunosorbent assay and virus neutralization assay, using WNV lineage 1 and 2. In addition, 95 bird serum samples from Albania and 29 horse samples from Kosovo were tested in ELISA. An overall seroprevalence rate of 22% was found in horses from Albania, wherea...

An artificial feeding system was used where citrated bovine blood was offered to male and female Amblyomma cajennense. Vestiges of blood, sweat, hair and exfoliated skin were used as phago-stimulants placed on the surface of the silicone membrane. The ticks were collected, as engorged nymphs, from naturally infested equines, with the ecdysis occurring in the laboratory. Four hundred ticks were ...
