En Colombia son limitados los reportes sobre frecuencias o prevalencias de parasitismo gastrointestinal en equinos, principalmente aquellos destinados a tracción. Los establecidos previamente por diversos autores describen que la identificación parásitos Strongylus sp, Strongyloides sp y protozoarios es común nivel siendo estos importancia clínica su potencial patológico. Por lo tanto, este est...

The article by Wu and colleagues in this issue describes an interesting case of asthma secondary to exposure to bloodworms in a laboratory setting. The use of bloodworms as a fish food has led to a number of differing manifestations dependent on the route of exposure. These include anaphylaxis, asthma, and urticaria/angioedema secondary to contact. A person who worked in an office setting in ou...

The faeces of 82 donkeys irrespective of sex and age were collected and examined for any parasitic ova. The faecal sample of68 donkeys were infected with: Strongylus sp. (54.87%), Parascaris sp. (29.26%), Strongyloides sp. (24.39%), Trichonema sp. (15.85%), Oxyuris sp. (8.53%), Gastrodiscus sp. (8.53%), Entamoeba sp. (8.53%), Dictyocaulus sp. (3.65%), and Triodontophorus sp. (2.43%).

UNLABELLED Little is known about the presence/absence and prevalence of Rickettsia spp, Bartonella spp. and Yersinia pestis in domestic and urban flea populations in tropical and subtropical African countries. METHODOLOGY/PRINCIPAL FINDINGS Fleas collected in Benin, the United Republic of Tanzania and the Democratic Republic of the Congo were investigated for the presence and identity of Rick...

Suppressive anthelmintic treatment strategies originally designed to control Strongylus vulgaris in horses were extremely successful in reducing morbidity and mortality from parasitic disease. Unfortunately, this strategy has inadvertently resulted in the selection of drug-resistant cyathostomes (Cyathostominea), which are now considered the principal parasitic pathogens of horses. Resistance i...
