Additional data are required from the dwarf sheep in the Sudanese region to ascertain the survival mechanisms of the parasite. A quantitative evaluation of strongyle eggs was performed using the modified McMaster method.

CESTODE – Definition and synonyms of cestode in the French dictionary

Parasitological findings Nematodes Sahelian sheep The following parasites species were recorded from Sahelian sheep in order of predominance: Angoras in a Merino world. However, conflicting results have been reported elsewhere in Africa McCulloch et al, and in Europe Le Riche et al, with different types of management. Bulletin of Animal Health and Production in Africa Therefore, the author concluded that starting in June-July-August, a new population of adult worms developed.

Selection of the abattoirs was based on the number of individual animals slaughtered daily and the probability of obtaining native animals from the various ecological regions of Mali. Cestodes The only larval cestode reported in this study is Cysticercus tenuicollis.

One hundred and fourteen goats out of the at the beginning of the experiment were analysed for the same purpose.

Sahelian goats Based on post-mortem examination, the following nematodes were identified in long-legged Sahelian goats in order of predominance: Further investigation is needed to assess the pathology of schistosomes in small ruminants because of increasing reports of damage that the parasite might cause in sheep Vercruysse, This parasitogical survey has shown that cestodee also share the same parasite species bun with different levels of infection.

Kouyate cesstodesS. Prior to anthelminthic treatment, animals were divided into five diferent treatment groups and all were immunised against pasteurellosis, anthrax, black leg and peste des petite ruminants PPR.

Journal of Helminthology Animals comprised exclusively Djallonke sheep and dwarf goats. Sheep, on the other hand, are used in ceremonial festivities throughout the country, providing important trade mainly male sheep between rural and urban areas. Climatic data Monthly temperature and rainfall data were obtained from the National Agroclimatological Office at Bamako. Sahelian axultes Trematodes were found with the following frequency: No significant change afultes noted on liveweight between the treated groups and the control in adult sheep ewes and rams.

Sudanese dwarf sheep Not a single F. The following nematodes were found in goats in order of predominance: Goats are often the main supply of daily meat in rural areas. Since effotts are being made in two ecological zones to assess the impact of mass anthelminthic treatment on production parameters such as weight and mortality.

Both animal breeds were owned by small individual households. Only one sheep was found to be infected with Schistosoma spp. Sudanese dwarf sheep The results obtained from this survey may not reflect the overall field situation due to a limited sample size from the abattoirs visited.

Journal of the Victoria Department of Agriculture Cestodes Cysticercus tenuicollis was widely distributed among small lfs in Mali. Bengaly 3 and W. William Heineman Medical Books Ltd.

Parasite profiles of sheep and goats from different geographic areas of Mali. Together, sheep and goats provide a large portion of the meat consumed and produce daultes considerable amount of manure, which is of special importance in those areas where cattle are of lesser importance. Graber recognised this parasite among native sheep of Senegal.

Trichostrongylus colubriformis, Haemonchus contortus, Strongyloides papillosus, Oesophagostonum columbianum, Gaigeria pectinata, C. Postmortem examination showed the following prevalence: Prevalence figures are given in Table 1. Gastro-intestinal parasites in small ruminants in Mali: Sudanese dwarf goats Only two nematode species were found in significant numbers. Both sheep and goats were found to adults infested with identical nematode species, however, with different levels of infestation.

III The response of sheep to primary infection with Haemonchus contortus. The maximum egg count was observed between August and October with a peak in September. These findings suggest that the parasite thrives in a region with higher rainfall. Fifty sheep out of 70 from the starting of the experiment were analysed for live weight changes. One hundred and fifty goats adlutes 70 sheep aged from birth to 24 months were grouped at random into different age categories prior to anthelminthic treatment.

No mortality was recorded. The difference in the level of infection and prevalence is probably due to difference in resistance to infection and grazing habits of the host species. These findings suggest that most of the larvae had undergone inhibition of development during the drier period of the year.

Control strategy in the semi-arid xdultes Materials and methods The experiment was carried out in the Djoni village located in the Bamako country, km north-east of Bamako with an average annual rainfall ranging from – mm. This decrease coincided with a sharp increase of the adult population suggesting the maturation of the immature worms. Variation in geographic distribution and prevalence were noted in relation to the season and management practices.
