Anthelmintic Resistant Heamonchus 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 anthelmintics currently used to treat Haemonchus contortus: the benzimidazoles, imidazothiazoles, and macrocyclic

Tooth wear in captive giraffes (Giraffa camelopardalis): Mesowear analysis classifies free-ranging specimens as browsers but captive ones as grazers

Captive giraffe (Giraffa camelopardalis) mostly do not attain the longevity possible for this species and frequently have problems associated with low energy intake and fat storage mobilization. Abnormal tooth wear has been among the causes suggested as an underlying problem. This study utilizes a tooth wear scoring method (“mesowear”) primarily used in paleobiology. This scoring method was applied to museum specimens of free-ranging ( n=20) and captive (n=41) giraffes. The scoring system allows for the differentiation between attrition- (typical for

Conservation of large mammals in the Republic of Mali

Populations of large wild mammals exist in one national park and several reserves and protected forest areas in Mali. In addition some wildlife survives in areas, in the south where onchocerciasis and trypanosomiasis, and in the north lack of available water, prevent human settlement. The area of present-day Mali has been populated by a succession of relatively advanced African states during the past 1500 years, who have influenced the vegetation and wildlife. An account of the present status of large

Carbohydrate in Pancreatic Ribonucleases

A survey of the presence and compositions of carbohydrate chains attached to pancreatic ribonucleases is given. Carbohydrate chains may occur at asparagine residues in Asn-X-Ser/Thr sequences at four exposed sites of the molecule (positions 21, 34, 62, and 76). These sites form part of highly variant sequences in pancreatic ribonucleases with the consequence that the enzymes from very closely related species may differ in the presence or absence of carbohydrate. In a number of ribonucleases Asn-X-Ser/Thr sequences occur which carry

Seasonal chemical composition of the diet of Transvaal lowveld giraffe

Rumen contents of giraffe (Giraffa camelopardalis) were collected over a 1-year period in the eastern Transvaal lowveld and crude protein, ether extract (fat), crude fibre, ash and gross energy content were determined. Variations in crude protein, ash and gross energy content of the diet could be related to changes in the composition of the diet of the giraffe and to seasonal phonological changes of the vegetation. There was no evident correlation for crude fibre or fat, but this could have

Reproduction in the giraffe in relation to some environmental factors

Environmental influences on reproduction in female giraffe were investigated by calculating conception dates for 123 calves and twenty foetal giraffe from the eastern Transvaal, South Africa. Of these, 60% occurred during the 4 months December to March. This period is the peak of the austral summer when plant leaf production is at a maximum, the preferred food species of the giraffe are abundant and the protein and energy content of these are high. Rainfall is also highest at this time.
