From this study, hematological and serum biochemical values were comparable to and not different from those reported for dogs in available literature, but the upper and lower reference limits (minimum and maximum values) were different for most parameters. Sex-related significant difference (p < 0.05) occurred only in WBC and total protein while age-related significant difference occurred only in total protein and urea level. Breed affected the MCHC and total bilirubin level which was evident in higher MCHC level in Neapolitan mastiff than Alsatian breed while total bilirubin was higher in Alsatian breed than Bull mastiff (p < 0.05). The present study has presented preliminary information on the range of hematological and serum biochemistry profile of exotic breed of dogs in Jos, Plateau state, Nigeria which may be useful to biomedical researchers and veterinary clinicians.展开更多

These naturally available materials are affected by the residual presence of pesticides. The concentration of pesticides in honey comb then reflects the leftover after degradation. In this study, samples of honey were collected from five different farms in Plateau State and analyzed for pesticide residues (atrazine, cypermethrin) and heavy metals (Pb, Cd, Cr, Fe and Mn) using GC-MS and AAS techniques. Results of the analysis indicated that atrazine and cypermethrin were found in the range (0.01 - 0.36 and 0.11 - 0.26) mg/kg, respectively in all the samples. Mn and Fe were found across the samples while Cd was detected only in the sample obtained from Maraban Jos (0.0013 mg/kg). Except Bokkos and Maraban Jos, Pb was detected in other samples. This study revealed that all samples contained the selected pesticide residues above the maximum residue limits recommended by European Union, while concentration of heavy metals in all the samples except Mn was below the maximum concentration limits recommended by Food and Agriculture Organization. The high concentration of pesticide residues in the samples indicates contaminated environment in which the bees fed;therefore intermittent monitoring of the quality of honeys produced would be necessary as this calls for urgent attention.</span> </div>展开更多

Women of reproductive age are mostly affected and infected with the HIV disease. Methodology: A cross-sectional study of 216 randomly selected women that booked for antenatal care at the Faith Alive Foundation and PMTCT centre Jos between 1st July to 31st December, 2014 was carried out. Information regarding age, parity, gestational age at booking, educational status and HIV sero-status of the clients was analysed. Screening test was conducted in a serial two step approval using determine and UNIGOLD as the confirmatory test, while STAT-PAK was the tie-beaker with discordant result as per the national algorithm. Positive samples were confirmed by western blot method. Result: A total of 18 women out of the 216 women studied were positive giving a sero-prevalence rate of 8.3%. The highest sero-prevalent rate was amongst 25 - 29 years age group (31.5%). Women of parity 1 - 4 constituted the highest group of 62.9%. Majority of the women 65.7% booked in the second trimester while 26.9% booked in the 3rd trimester. Most of the women 47.2% had secondary school education while only 5.6% of them had no form of education. Conclusion: HIV infection prevalence rate among antenatal attendants at Faith Alive Foundation and PMTCT centre Jos is still high. Multisectorial approach and intervention strategies should be further scaled up for the prevention of vertical transmission of the virus. However, it is worth noting that it is mainly an HIV/AIDS hospital which should have affected the outcome.展开更多
