    Epidemiology of intestinal helminth parasites of dogs in Ibadan, Nigeria
    (Journal of Helminthology, 2008-03) Sowemimo, O.A.; Asaolu, S.O.
    An epidemiological study of gastrointestinal helminths of dogs (Canis familiaris) in two veterinary clinics in Ibadan, Nigeria, was conducted between January 2001 and December 2002. Faecal samples collected from 959 dogs were processed by modified Kato–Katz technique and then examined for helminth eggs. The results of the study showed that 237 (24.7%) of the dogs examined were infected with different types of helminths. The prevalences for the various helminth eggs observed were: Toxocara canis 9.0%, Ancylostoma spp. 17.9%, Toxascaris leonina 0.6%, Trichuris vulpis 0.5%, Uncinaria stenocephala 0.4% and Dipylidium caninum 0.2%. The faecal egg intensities, determined as mean egg count/gram of faeces (^SEM), were: T. canis 462.0 ^ 100.5, Ancylostoma spp. 54.1 ^ 8.6, T. leonina 0.8 ^ 0.4, T. vulpis 0.1 ^ 0.0, U. stenocephala 1.0 ^ 0.7 and D. caninum 0.2 ^ 0.1. Host age was found to be a significant factor with respect to the prevalence and intensity of T. canis and Ancylostoma spp. There was no significant difference in the prevalence of intestinal helminth parasites between male (27.0%) and female (22.5%) dogs (P . 0.05). The prevalence of helminth parasites was significantly higher (P , 0.05) in the local breed (African shepherd) (41.2%) than in Alsatian dogs (16.2%) or in other exotic breeds (21.0%). Single parasite infections (85.7%) were more common than mixed infections (3.5%).

    SEASONAL TESTICULAR HISTOLOGY AND REPRODUCTIVE CYCLE OF THE RAINBOW LIZARD, Agama agama agama , L, (AGAMIDAE, REPTILIA) IN ILE-IFE, SOUTH WESTERN NIGERIA
    (Animal Research International, 2008-05) EJERE, Vincent Chikwendu; ADEGOKE, Joseph Adeleke
    Seasonal histological features of the t e stis an d e p i d idym is were stud ied in male A. aga m a agama r om Jul y l 990 t o June, 1 9 92 at Il e-If e, Ni g e ri a. Test s w e ig ht s show ed no si gni c ant di f e rence (P > 0. 05) i n t h e d r y and rai n y seasons, but w e re ge nerally low f r om August to January. Whereas seminiferous tubule diam eter and epithelia heights showed no se asonal variation (p > 0.05), t h e epidi d ymal t u bule diamet er and epith e lia height s varied seasonally (P < 0 001 ). Although males in full breedin g condition we re caught all through the months, such were more prevalent from April to July. Female s with egg s or enlarged ovarian fo llicles were caught all through the study period. Cases o f mul tiple clutch es were predo m inant fro m February to J u ly. Ho wever vitello gen c activitie s decreased fr o m August to January thus co inciding with the observed decre a se in sperm a togenic activity in th e male. We propose that indivi dual m a le Agama li zards mainta in pecu liar b r eedin g patterns and that re prod uction in A g ama seems t o be influenc ed by food a vailability as well as microclimatic conditions at oviposition sites

    Analysis of Pesticide Raid® in Feed of Wistar Rat by High-Pressure Liquid Chromatography (HPLC)
    (Albert C. Achudume, 2011-12-31) Achudume, Albert C.
    The distribution of pesticide by-product in tissues of wistar rats were analyzed using high pressure liquid chromatography. The limit of detection of the HPLC was 0.1 µg. Results show bioaccumulation factor of pesticide “Raid®” in lipid, up to three times that of the feed at the first concentration and gradually decreased as the concentration increased in the muscle > (0.7), brain > (0.5) and liver > (0.3) as indicated in the text. At higher concentration of 961 µg/g, bioaccumulation factor decreased in the lipid to 1.2 and 0.6 in the muscle, 0.03 in the brain and 0.08 in the liver respectively. High Pressure Liquid Chromatography (HPLC) analysis of raid extract suggests the presence of micprothrin and palethrin. The implications are numerous, but simply put that accidental ingestion of chlorinated hydrocarbon as in “Raid®” may involve convulsions, collapse and coma after only brief excitation and ataxia at the onset.

    Assessment of the water quality parameters in relation to fish community of Osinmo reservoir, Ejigbo, Osun State, Nigeria
    (2014-10-14) KOMOLAFE, O.O; ADEDEJI, A.A; FADAIRO, B
    Physicochemical indices of water body changed seasonally and this necessitated an investigation to assess the water quality parameters of Osinmo reservoir in relation to its fish species. The water quality parameters were measured using standard methods. Results obtained show that the reservoir is alkaline in nature with dissolved oxygen concentration (1.8-7.2 mgl-1) and alkalinity (64 CaCO3 mgl-1-108 CaCO3 mgl-1) which were within the optimum range for growth and survival of fish. Four families of fish comprising eight species were encountered. The sex-ratio of five species which were statistically different (P<0.05) indicated reproductive efficiency populations while other fish species whose sex-ratio differed insignificantly (P>0.05) revealed a growing population. The well-being of the fish species was adequate as observed in the least mean condition factor of 0.666±0.057 in C. gariepinus and the highest mean of 2.000±0.242 in S. galilaeus. The productivity of the reservoir can be improved through proper management of the water body
