Four single-strand conformation variants of the bovine tumor necrosis factor alpha gene by analysis of PCR-amplified fragments were identified. The variants are inherited in Mendelian fashion and are informative for linkage mapping. We have mapped the bovine gene to Chromosome (Chr) 23 in a panel...

Human chromosome (Chr) 18(HSA 18) contains approximately 85 million base pains of DNA. Thirty genes and pseudogenes have been mapped to HSA 18 by somatic cell genetics or in situ hybridization. Two bovine genes - Yamaguchi sacroma viral oncogene homology 1 (YESI) and desmocollin type 1 (DSC1) - h...

There is an alarming rate of human African trypanosomiasis recrudescence in many parts of sub-Saharan Africa. Yet, the disease has no successful chemotherapy. Trypanosoma lacks the enzymatic machinery for the de novo synthesis of purine nucleotides, and is critically dependent on salvage mechanis...

Blood samples were collected from parasitaemic cattle in the Ghibe Valley, Ethiopia, frozen in liquid nitrogen and transported to Nairobi, Kenya. Twelve of the stabilates were inoculated into individual Boran (Bos indicus) calves and characterised for their sensitivity, in turn, to diminazene ace...

An average of 840 East African Zebu cattle from nine herds in the Ghibe Valley, southwest Ethiopia were monitored from 1986 to 1990. Each month blood samples were collected from analysis of packed red cell volume and detection of trypanosomes. Animals were found to be parasitaemic and with a PCV ...

GI nematodes are most commonly controlled by chemotherapy. Anthelmintic efficacy is decreasing as drug resistance becomes widespread and other approaches are needed. Knowledge of protective immunity against GI parasites is important for the development of vaccine strategies. Success in this field...
