A survey of soil transmitted helminthes (STH) in different markets of Benin City was carried out using the test-tube floatation method. A total of three hundred (300) samples from different sections of the markets were examined and 82 (27.33%) samples had various geohelminth eggs. The parasite prevalence rates were Ascaris lumbricoides (30.99%), Necator americanus (20.25%), Trichuris trichuria (16.12%), Strongyloides stercoralis (10.33%). The prevalence of these helminth eggs is attributed to indiscriminate disposal of faeces and refuse in and around the markets.

Enzyme-Linked Immunosorbent Assay (ELISA) for the diagnosis of fascioliasis due to F. gigantica was found to be more sensitive for the diagnosis of fascioliasis when compared with Faecal Egg Examination (FEE). An average monthly prevalence of 79.3% was observed for ELISA while FEE gave a prevalence of 28%. This indicates that parasitological methods of diagnosis underestimates parasite prevalence. There is therefore need to use conventional method of diagnosis in association with serological diagnosis.

Microbiological qualities of 32 samples of smoked fish belonging to 4 species of fish namely: Clarias gariepinus, Oreochromis niloticus, Citharinus citharus and Synodontis membranaceous; from four (4) local markets (Monday Market, Sabo Market, Malale Market, Awuru Market) were studied. In most samples, moisture contents were high, 53.12% of the fish samples have moisture content above 30% level. The smoked samples were dominated by gram-positive bacteria however, potential pathogens, coagulase positive staphylococci, and Escherichia coli were isolated from some of the samples.

The presence of Gallstones in the gallbladder is known to cause irritation of the gallbladder wall thereby resulting in the thickening of the gallbladder wall. On the other hand, an inflamed gallbladder, with its thickened wall, has been postulated to encourage super-saturation of gallbladder bile and subsequent gallstone formation. This study was therefore designed to determine the relationship between the presence of Gallstones and Gallbladder wall thickness.

Upper gastrointestinal tract endoscopy is a visual examination of the upper intestinal tract using a lighted, flexible fibreoptic or videoscope. Common reasons for upper gastrointestinal tract endoscopy include ulcers (benign and malignant), intestinal bleeding, oesophagitis and heartburn, gastritis etc. This study is therefore to examine the common indications for upper gastrointestinal tract endoscopy at ECWA hospital, Egbe. Kogi state.

A total of eighteen fishes belonging to two families Claridae and Chichlidae were encountered in this study. Out of the eighteen fishes, nine (50%) were found to harbour mostly parasites of the class Nematoda

The anticoccidial efficacy of the aqueous neem leaf extract in comparison to amprolium showed that the aqueous extract dose of 800mg/kg compared favourably with 10mg/litre of amprolium in treating the disease, both showed 100% survival rates for infected and treated chickens with zero oocyst per gram at day 4 post treatment. Also, the mean weight (grams) of infected and treated chickens improved significantly (P<0.05) at day 7-post treatment.

A total of 250 cattle claughtered at Maiduguri abattoir were examined, random sampling to ascertain the rate and level of meat condemnation due to fascioliasis, hydatidosis and cysticercosis. 202 (80.8%) of the cattle examined were confirmed positive for infection. Data on estimated losses in Naira equivalent and condemnation in weight (kg) showed that fascioliasis had 539.41kg, hydatidosis, 268.0kg and cysticercosis 483.19kg with an estimated economic value of N188, 804, N93, 800 and N169, 116 for fascioliasis, hydatidosis and cycticercosis respectively.

The land mollusc fauna in a single square kilometer of undisturbed tropical rainforest in Okomu National Park, Edo State, Nigeria was surveyed by sampling thirty 20-m2 plots. Sampling methods were similar to those used in the rainforests in Cameroon and Sabah. Samples were collected by sieving leaf litter, topsoil and by hand picking within the forest floor or vegetation. A total of 1442 individual molluscs belonging to 46 species in 11 molluscan families were collected.

120 fingerlings of Clarias gariepinus were fed five different experimental 35% isoproteic diets, a control (0% water hyacinth) and four diets containing different levels of water hyacinth (10%, 20%, 30% and 40%) in place of fish meal as protein source at %% of the body weight for 70 days under laboratory condition. The study revealed a decrease in the growth performance indices as the level of water hyacinth increases.
