| Summary: | Cattle production accounts for over sixty percent of meat requirement in Cameroon but helminthosis greatly hinders its productivity. A study on worm burdens in digestive and pulmonary organs of cattle was done between February 2018 and January 2019 at a Research Centre in Cameroon with fourteen apparently healthy adult cattle that were necropsied. Recovered worms were adequately processed and identified with standard keys. Data were subjected to descriptive statistic and worm burdens recorded according to sex of worms, as well as breeds and sex of cattle. Analysis of variance (ANOVA) in general linear model on raw values was summarized as arithmetic means with standard errors of means. Mixed-model ANOVA verified relationship of worm burdens with cattle breed and sex. Nine Nematodes (Haemonchus contortus, Cooperia species, Trichostrongylus axei, Trichuris globulosa, Oesophagostomum radiatum, Nematodirus species, Ostertagia ostertagi, Dictyocaulus viviparus, Setaria labiatopapillosa ), two Trematodes (Calicophoron microbothrium and Fasciola gigantica), and one Cestode (Echinococcus granulosus Hydatid cysts) were recovered at necropsy. Total worm burden was 42252; commonest infections being Haemonchus contortus (40.9%) , Cooperia species (38.2%) , and Trichostrongylus axei (9.5%) . Female worms 28503(67.5%) established more than males 13644(32.3%). Hermaphrodites were only 105(0.3%) of total worm burden. Worm burden/cattle was 3018 (2966/bull and 3027/cow) but for cattle breeds, burdens were 3331/Namchi (600/Namchi bull and 4696/Namchi cow) and 2933/Gudali (5331/Gudali bull and 2693/Gudali cow). Gudali breed showed more parasitic infections than Namchi, but the difference being statistically non-significant (P > 0.05). Worm burden/cattle was 3018 with an average of 2966/bull and 3027/cow but for cattle breeds, burdens were 3331/Namchi with and average of 600/Namchi bull and 4696/Namchi cow and 2933/Gudali with an average of 5331/Gudali bull and 2693/Gudali cow. Sex wise females recorded higher infection rates than males but the difference being statistically non-significant (P > 0.05). Hypobiotic larvae were not found in the digestas. Morphological identification of helminths has provided basis for further moléculaire identification to ensure sustainable helminthosis management intervention. Meanwhile strategic anti-helminth treatments will usefully control infections and re-infections in cattle in the area.
