(Elsevier Science B.V., 1996-10) Muhairwa, A.P; Chibunda, R.T; Kambarage, D.M; Mtambo, M.M.A; Kusiluka, L.J.M; Kazwala, R.R
Coccidial oocysts were detected in 35% of 445 cattle in four medium-scale and 20 small-scale dairy farms in Morogoro municipality, Tanzania. The highest prevalence (56%) was observed in animals aged between 5 and 18 months, whereas lower prevalences were observed in calves (29%) aged between 12 days and 4 months and adults (30%). No coccidial oocysts were detected in calves less than 12 days old. The oocyst output was high in calves, followed by weaners; adults had the lowest oocyst output. The number of oocysts per gram of faeces was significantly higher (P < 0.001) in diarrhoeic animals than in non-diarrhoeic animals, and more so in young calves. Eimeria species infecting the animals included Eimeria bovis (68%) and Eimeria zuemii (57%), Eimeria ellipsoidalis (25%), Eimeria cylindrica (23%), Eimeria aubumensis (22%), Eimeria alabamensis (12%) and Eimeria subspherica (5%). Mixed infections involving two or three species were common. Our findings indicate that eimeriosis is common in cattle in Morogoro municipality. Published by Elsevier Science B.V.
Helminthosis in local and cross-bred pigs in the Morogoro region of Tanzania
(Elsevier, 1997-01) Muhairwa, A.P; Mtambo, M.M.A; Kambarage, D.M; Elsrony, K; Kusiluka, L. J. M
We investigated the prevalence, burden and types of gastro-intestinal helminths in 424 local and cross-bred pigs kept under different management systems in two climatic zones in the Morogoro region of Tanzania. Coprological examination revealed that 53% of the pigs excreted hehninth eggs in their faeces. The median eggs per gram of faeces (EPG) was 500 (range 100-22000). Local breeds in the Mgeta location with tropical highland climate showed signifi- cantly higher prevalence (P < 0.001) and median EPG values ( P < 0.001) than the cross-bred animals in the semi-arid area. There was no significant difference in the prevalence (P = 0.90) of helminth infection and egg outputs (P = 0.78) in cross-bred pigs raised under the small-scale and semi-mtensive management systems in the semi-arid zone. Piglets showed significantly lower prevalence of helminthosis (P < 0.001) than the weaners, growers and adults in both local and cross-bred animals. Median EPGs of growers and adult animals were significantly higher than those of piglets and weaners (P = 0.006). The prevalences of various hehninth species were Oesophagostomum sp. (40%), Ascaris suum (12%), Strongy loides ransomi (9% ) and Trichuris suis (St% ). 0 1997 Elsevier Science B.V.
Preliminary Observation on accessibility and utilization of water in selected villages in Dodoma rural and Bagamoyo districts, Tanzania

Studies on mastitis, milk quality and health risks associated with consumption of milk from pastoral herds in Dodoma and Morogoro regions, Tanzania
(2005) Karimuribo, E.D; Kusiluka, L.J; Mdegela, R. H.; Kapag, A.M; Sindato, C; Kambarage, D.M
The prevalence of mastitis, milk quality and health risks associated with milk consumption were investigated on 96 randomly selected traditional herds in Dodoma rural and Mvomero districts of Tanzania. Mastitis was investigated based on clinical signs, microbiology and California mastitis test (CMT), while milk quality was evaluated using total viable count (TVC) and total coliform count (TCC). Animals were tested for tuberculosis using a single comparative intradermal tuberculin test. The prevalence of subclinical mastitis based on CMT was low (8.3%). The major isolates were Staphylococcus aureus (35.3%), other staphylococci (20.8%), coliforms (27.7%), microcci (5.8%) and streptococci (9.8%). The average TVC of milk in Dodoma rural district (1.0 × 107± 3.4 × 107) was significantly higher than that in Mvomero district (8.9 × 105± 3.5 × 106) (p < 0.001) and the proportion of TCC-positive samples in Dodoma (70.7%) were significantly higher (p < 0.001) than that of Mvomero samples (20.8%). Whereas no tuberculin reactor animal was detected in the study animals, atypical mycobacteria were isolated from milk and one sample from Dodoma had Mycobacterium tuberculosis. Knowledge on health risks associated with milk consumption was low (20.8%). It is concluded that lack of awareness on health risks associated with milk consumption amongst rural communities needs to be addressed in order to safeguard their health.
