[Ticks and hemoparasitic diseases in cattle in Senegal. IV. The southern Sudan area].

The authors report on the results of an investigation on ticks and hemoparasitoses of cattle, sheep and goats in the South Sudanian area of Senegal. Systematic routine dipping against ticks of cattle, 40 sheep and 40 goats was set during 15 months, with a view to determine the population dynamics together with an acurate localization of the different species concerned. The following parasites were collected from these ruminants: Amblyomma variegatum, Boophilus geigyi, Hyalomma truncatum, H. m. rufipes, Rhipicephalus lunulatus, Rh. sulcatus, Rh. e. evertsi, Rh. senegalensis. At the same time joint research was conducted on hemoparasitoses by mean of blood smears and of splenectomy. In cattle were found Theileria velifera, Th. mutans, Anaplasma marginale, Babesia bigemina, Ehrlichia bovis, and microfilaria of Setaria labiatopapillosa. Anaplasma ovis, Theileria ovis, Ehrlichia ovina, Trypanosoma vivax, T. congolense are involved in infections detected in goats and sheep. Among grown up and found apparently healthy animals, the hematocrite values have been studied as well as the seasonal variations of the haematological parameter.

[Seroepidemiologic studies of the agent of respiratory diseases in cattle].

In a period of three years epidemiological studies were carried out in Styria concerning the occurrence of antibodies against BRSV (Bovine Respiratory Syncytial Virus), Adeno I Species 3-Virus, Adeno II Species 8-Virus, PI-III (Parainfluenza 3-Virus), IBR/IPV-Virus and Chlamydia. A total of 1376 serum samples were examined and showed different titers of specific antibodies against respiratory pathogens. 449 blood samples were submitted to serological examinations in the year 1984, 525 in 1985 and 402 in 1986. Antibodies against BRSV could be found in 17.4% of the sera or in 55.9% of the herds. Specific antibodies against Adeno I Species 3 occurred in 33.9% of the sera resp. in 74.2% of the units. 35.2% of the cows or 80.1% of the herds showed positive SN-titres against Adeno II Species 8. IBR/IPV-specific antibodies were detected in 2.3% of the sera resp. 3.8% of the herds. Antibodies against Chlamydia could be found in 8.8% of the cows or in 22.6% of the units. In the years mentioned above significant differences of antibodies against BRSV, Adeno I Species 3, Adeno II Species 8 and Chlamydia could be observed, but not against PI-III and IBR/IPV as well. By means of the Chi-Square-Test significant differences between Simmentaler, Austrian Brown Cattle and Holstein Friesian regarding antibodies against IBR/IPV and Adeno II Species 8 could be found. No significant differences between the serological results of herds, which contained on of the three breeds could be observed.

The relationship of Oxytropis sericea (green and dry) and Astragalus lentiginosus with high mountain disease in cattle.

All calves fed locoweed (green and dry Oxytropis sericea Nutt and dry Astragalus lentiginosus Dougl) at high elevation developed clinical signs, gross and microscopic lesions of congestive right heart failure. Clinical signs and microscopic lesions of locoweed intoxication were also evident. Control calves did not develop the clinical signs, gross or microscopic lesions demonstrated in the locoweed fed calves.
