    Abstract: Examination of the gastrointestinal tract of 96 cattle slaughtered at the Yola Modern abattoir during the period April 2008 to March 2009 indicated a prevalence of 75% for naturally acquired infections with <I>Trichostrongylus</I> sp. (42%; <I>Cooperia</I> sp. (31%), <I>Strongyloides</I> sp. (24%), <I>Oesuphagostomum</I> sp. (44%), <I>Bunostomum</I> sp. (11%), <I>Oestertagia</I> sp. (3%), <I>Syngamus</I> sp. (2%) and <I>Toxoplasma</I> sp. (4%), respectively. There were no significant differences (p&gt;0.05) in prevalence between sexes and age groups. Out of the 72 infected cattle, 59 or 88% had burdens of &lt;500 worms while burdens of 500-1000 and &gt;1000 were encountered in 6 or 8% and 7 or 10% of the cattle, respectively. A significantly (p&lt;0.05) greater number of cattle harbored &lt;500 worms. Although, most of the parasites occurred throughout the study period, higher worm counts were generally encountered during the rainy season than in the dry season.
