    Prevalence of Gastro- intestinal Parasites of Sheep slaugtered at Keffi Abattoir, Nasarawa Sate, Nigeria
    (Department of Zoology, Nasarawa State University Keffi, 2020-06-11) Mairiga, M.A.; Okaku, M.S.; Tongjura, J.D.C.; Sani, Z.R.
    This study investigated the prevalence of gastrointestinal parasites of sheep slaughtered in Keffi main abattoir conducted from June to July 2019. One hundred and fifty (150) fecal samples comprising of 60 Yankasa, 18 West African dwarf (WAD), 33 Balami and 39 Uda breed were collected from the abattoir. The samples were taken to the Laboratory to examine the intestinal helminthes eggs and protozoan oocysts using sodium chloride floatation and sedimentation techniques. Out of 150 samples examined, 84(56.0%) had gastrointestinal parasites. The Yankasa breed had the highest prevalence of 32(38.1%), while the WAD breed had the lowest prevalence of 12(14.3%). Female had the highest prevalence of 54(64.3) than male which have 30(35.7%). Young sheep had the highest prevalence of 52(61.9%) than adults which had prevalence of 32(38.1%) respectively. The gastrointestinal parasites encountered were Strongyles edentates sp., Coccidian spp., Haemonchus spp., Trichostrongyles spp and Fasciola spp. Trichostrongyles spp., had the highest prevalence of 23(27.3%) while coccidian had the lowest prevalence of 4(4.7%). Chi-square statistical analysis revealed no significant difference (p>0.05) among the breed, age, and sex of the sheep. The result of the study shows that high prevalence of gastrointestinal parasites among the sheep breed, therefore with good management practice, prompt diagnosis, treatment with antihelminthes drugs and mass education of farmers on the importance of hygiene and sanitation will reduce the risk of the disease and increase productivity.

    STUDIES OF CO-INFECTION OF MALARIA AND HEPATITES B AMONG PATIENTS ATTENDING INNOVATIVE BIOTECH KEFFI, NIGERIA
    (Department of Zoology, Nasarawa State University Keffi, 2020-01-11) Mairiga, M.A.; Vincent, J.T.; Tongjura, J.D.C.; Sani Z.R.
    Malaria has been described as entirely preventable and treatable blood-borne mosquitos’ transmittable disease. However, despite continuous global efforts at all levels of health care to achieve global control, it still remains endemic in tropical and subtropical region, though with decreasing trend (WHO, 2012; 2013). Co-infections are becoming common risk factors that may contribute to the increased burden of morbidity in Patience. The aim of this study was to assess co-infections of malaria, hepatitis B (HBV), conducted at innovative Biotech Keffi, Nasarawa State, Nigeria, from June to August 2019. A total of 200 patients were examined for malaria and HBV status. A total prevalence of 25%, 44% and 12.5% for malaria, HBV and co-infection was recorded respectively. For both sexes, age group between30 to 39 had the highest prevalence for malaria, while 20-29 had the highest prevalence for HBV. Similarly, the age group between20 to 29 had the highest prevalence for co-infection of malaria and HBV. No prevalence was recorded in age group ≤ 9 in male for malaria, HBV and co-infection. The results indicated that there was no significant difference between patients in relation to sex (P˃0.05). It was concluded that co-infection of malaria and HBV had effect with varying immunity in relation to age. In view of these findings, further studies involving large samples are recommended

    SURVEY OF THE DISTRIBUTION AND ABUNDANCE OF BENTHIC MACRO-INVERTEBRATES IN NASARAWA STATE UNIVERSITY MAIN STREAM, KEFFI, NIGERIA
    (Department of Zoology, Nasarawa State University Keffi, 2021-01-03) Mairiga, M.A.; Tongjura, J.D.C.
    This study aimed to survey the distribution and abundance of benthic macroinvertebrates conducted at Nasarawa State University Keffi, main stream between January and June 2019. The stream was divided into three sampling points A, B and C at a distance of 50 m apart. Samples were collected from each point using hoe, transferred into a plastic container and transported to the laboratory in a cooler for analysis. A total of 2,365 benthic macroinvertebrates comprising Chiromomid larvae 2015 (85%), Dragon Fly Nymphs 120 (5.1%), May Fly Nymphs 111 (4.7%), Molluscs 89 (3.7%) and Annelidworms 30 (1.2%) were recorded. The highest number of benthos was recorded at point B (30.5%) and the lowest in point C (30.2%).Water parameters was found to have an effect on the abundance and distribution pattern of the benthic macro-invertebrates. ANOVA results did not evidence significant differences on the distribution and abundance of benthic macroinvertebrates between the sampling points at P ˃0.05

    SUSCEPTIBILITY STATUS OF Anopheles MOSQUITO TO PIRIMIPHOSE METHYL AT RIVER UKE, NASARAWA STATE, NIGERIA
    (Department of Zoology, Nasarawa State University Keffi, 2021-01-10) Mairiga, M.A.; Kelechi, T.A.; Tongjura, J.D.C.
    This study was conducted to investigate the susceptibility and resistance status of Anopheles gambiaes.l to Pirimiphose Methyl at River Uke, Nasarawa State, Nigeria from May to July 2019. Anopheles mosquito larvae were collected from the upper and lower locations of the river usually between the hour of 9am to 2pm at the interval of two weeks by dipping and scooping methods. The samples were taken to Entomology Laboratory and Insectary of Nasarawa State University, Keffi and reared to adult stage. A total of three hundred (300) female Anopheles mosquito from each adult cage (Upper and Lower locations) were subjected to 20 μg does of Pirimiphose methyl for susceptibility test at a time interval of 0, 15, 30, 45 and 60 min for 24 h in which 25 mosquitoes were exposed to each of the 4-impregnated CDC bioassay bottles. The result indicate that susceptibility (98-100%) and possible resistance (97-98%) was observed at 60 min exposure time. Data analysis by ANOVA showed no significant difference between the Upper and Lower locations of the study area (p>0.05).
