Points of collection are shown in Figure 1.

Sudanese dwarf goats Only two nematode species were found in significant numbers. Mao of Mali showing major rivers and collection sites. Prior to anthelminthic treatment, animals were divided into five diferent treatment groups and all were immunised against cestodfs, anthrax, black leg and peste des petite ruminants PPR. Long-legged sheep and goats are found in the Sahelian regions, and the dwarf breed are found in the Sudanese region of Mali.

Therefore, the author concluded that starting cestoddes June-July-August, a new population of adult worms developed.

To obtain data on seasonal variations in parasite populations and biology, attempts were made to make a minimum of four collections at most sites. Goats are often the main supply of daily meat in rural areas.

Sohael A S and Umo I. No significant change was noted on liveweight between the treated groups and the control in adult sheep ewes and rams. However, conflicting results have been reported elsewhere in Africa McCulloch et al, and in Europe Le Riche et al, with aduptes types of management. Nematodes Haemonchus contortus Heavy infections coincided with the rainy season, then progressively declined during the dry season.

Results and discussion Our findings demonstrated that lambs were more heavily infected by trichostrongyles because they were more lds. Parasitological findings Nematodes Sahelian sheep The following parasites species were recorded from Sahelian sheep in order of predominance: One hundred and fifty goats and 70 sheep aged from birth to 24 months were grouped at random into different cesyodes categories prior to anthelminthic treatment.

Due to a limited sample size, the results of this investigation concerning the dwarf sheep may not reflect the overall field situation. Fifty sheep out of 70 from the starting of the experiment were analysed for live weight changes.

Prevalence figures are given in Table 1. The dynamics of the host-parasite relationship.

The following nematodes were found in goats in order of predominance: Introduction Sheep and goats, although representing an important source of animal protein adults semi-arid countries such as Mali, seem to have benefited little from veterinary care and production improvement.

However, ewes remained infected all year-round thus serving as the source of contamination for the lambs.

Galgeria pachyscells Since the first report on the occurrence of the hookworm Gaigeria pachyscelis in sheep and goats in South Africa Orlepp,a wide distribution of the parasite has been reported in tropical Africa. A helminth survey of sheep and goats in Cyprus, Part I. Both sheep and aadultes were found to be infested with identical nematode species, however, with different levels of infestation. In Mali, it appears from this study that nodular form of the infection is of greater economic importance with a prevalence rate of 25 to William Heineman Medical Books Ltd.


Both animal breeds were owned by small individual households.

Studies of parasitic helminths of sheep and goats in Ghana. A quantitative evaluation of strongyle eggs was performed using the modified McMaster method. The anthelminthic treatments were as follows: Bulletin of Animal Health and Production in Africa Four trematodes Fasciola gigantica, Dicrocoelium nospes, Paramphistomum spp and Carmyerius sppone larval Cysticercus tenuicollis and three adult cestodes Monezia, Stilesia, and Avitellina were identified.

Furthermore, the study showed that from January onwards, as the hypobiotic larvae started to mature, these new adults gradually replaced the older population and seeded the pasture with eggs. 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. Parasite profiles of sheep and goats from different geographic areas of Mali. Sudanese dwarf goats No Fasciola was recovered in these goats in the course of this investigation.

Postmortem examination showed the following prevalence:
