To study the occurrence of the experimental struvite urolithiasis in goats in a semi-arid region of the Canary Islands, where urolithiasis is relatively common, 18 one-year old Canary female goats were divided into three equal groups: Group A received a concentrate ration of 3 parts corn to 1 part cottonseed meal; Group V received the same diet with wheat straw added ad libitum and Group C received a balanced diet for 10 weeks. Crystaluria was observed in all groups, but was more evident in Group A Goats belonging to this group showed a progressive calcium/phosphorus disbalance. Epithelial cells and bilirubin crystals were also more evident in the Group A. It is concluded that high grain diet resulted in struvite urolithiasis in goats.

Trypanosoma evansi was diagnosed for the first time in the Canary Islands (Spain) in 1998 in a dromedary camel. Seroprevalences of 4.8% up to 9% have been observed using different diagnostic methods. Affected animals have been treated but the dissemination of the disease is unknown. This article presents an outbreak of abortions and high neonatal mortality attributable to T. evansi infection in camels as well as the clinical assessment of the affected animals. The patients were diagnosed by routine checking (three pregnant animals), after abortion (five dams), or after delivered premature or weak calves (eight dams). At clinical examination, 2 out of 16 affected animals showed moderate signs of chronic form, particularly hyporexia and intolerance to exercise. The aborted fetuses were aged 6-8 months of gestation, approximately. The main laboratorial findings were regenerative anemia (haemolytic anemia), lymphocytic and monocytic leukocytosis, hyperproteinemia, hyperglobulinemia, hypoglycaemia, serum urea increased and serum iron decreased. Treatment using trypanocidal drug (Cymelarsan) resulted highly effective. Massive treatment would be recommended in the entire camel population in the Canary Islands (less than 2000 animals), as therapeutic or preventive measure, in order to control and to achieve an eventual eradication of the disease.

DEAE (anion exchanger diethylaminoethyl)-cellulose and mini Anion Exchange Centrifugation Technique (mAECT) allow salivarian trypanosomes to be separated from the blood of affected animals. The purpose of this study was to assess the mAECT in goats infected with T evansi. Five adult Canary goats were inoculated intravenously with at least 1 X 105 T. evansi isolated from a dromedary camel in the Canary Islands. The goats were monitored for specific antibodies and parasite detection. The inoculated goats became infected and the parasitemia remained very low but was persistent. For mAECT columns, the DEAE gel was equilibrated with phosphate-buffered saline glucose. T evansi was detected by its mobility with a microscope at low magnification (10 X 10). The mAECT proved to be more sensitive than blood smear and buffy coat but less sensitive than mouse inoculation. We conclude that in cases of very low parasitemia in goats, mAECT can be used when other parasite-detection tests have failed.

In 1998, two cases of silica urolithiasis occurred in castrated male dromedaries on an intensive camel farm in the Canary Islands. The immediate attributable cause was the ingestion of large amounts of silica in the feed, estimated as 84.44 g/day. An associated cause was the low level of salt in the diet. Daily ingestion of salt from feed and water was estimated to be 21.8 g (8.6 g of sodium). Seventy-six castrated males from the same farm were divided into four groups: group A received 30 g of salt daily; group B received 40 g; group C received 60 g; and group D received no added salt in the diet (control). The animals were maintained on these dietary regimes for 2 years. No animals from groups A, B or C suffered overt urinary retention. One animal from group D had an obstructive urinary retention 10 months after the study commenced. Thus, 52 g of salt daily appears to be sufficient to prevent urinary retention in dromedaries raised in a subtropical climate.

A 16-year-old, male, Hanoverian horse had a three-month history of weight loss, hirsutism and polyuria/polydypsia. Examinations revealed neutrophilia, lymphopenia, hyper glycaemia and abnormalities in hepatic function. A tentative diagnosis of hyperadrenocorticism was made. The results of thyroid-releasing hormone and combined dexamethasone suppression and ACTH stimulation tests suggested the presence of a pituitary adenoma. The horse was treated with pergolide and benefical clinical and biochemical responses were observed within one to six months.
