anthelmintic resistant haemonchus contortus in a giraffe (giraffa camelopardalis) in florida.a young male giraffe (giraffa camelopardalis) recently acquired by the lion country safari in loxahatchee, florida, was diagnosed and successfully treated for haemonchus infection while in quarantine. seven weeks after introduction into a group of resident giraffes, this giraffe presented with diarrhea. fecal evaluation revealed an extremely high count of 16,700 eggs/g, with larval identification of the parasite as haemonchus. a larval development assay showed resistance to the three classes of ...200919368252
morbidity and mortality factors in key deer (odocoileus virginianus clavium).the population health of endangered key deer (odocoileus virginianus clavium) was monitored from 10 february 1986 to 28 september 2000 by necropsy of animals that were killed by vehicles, euthanized because of terminal injuries or disease conditions, or found dead. the predominant mortality factor during the period was collision with motor vehicles; however, several infectious diseases were diagnosed, including infections with arcanobacterium pyogenes, haemonchus contortus, salmonella spp., and ...200212528433

accuracy of the famacha system for on-farm use by sheep and goat producers in the southeastern united states.famacha is a practical on-farm system designed to provide small ruminant producers a tool for improving their management of haemonchus contortus infections. although this system has become very popular and widely accepted by small ruminant producers in many regions of the southern united states, there is very limited data reported on the effectiveness of the famacha system when performed by farmers. the objective of this study was to evaluate the accuracy of the famacha system for on-farm use by ...200717482368
validation of the famacha eye color chart for detecting clinical anemia in sheep and goats on farms in the southern united states.recent studies on sheep and goat farms in the southern united states indicate that multiple-anthelmintic resistance in haemonchus contortus is becoming a severe problem. though many factors are involved in the evolution of resistance, the proportion of the parasite population under drug selection is believed to be the single most important factor influencing how rapidly resistance develops. therefore, where prevention of resistance is an important parallel goal of worm control, it is recommended ...200415265575
