Occurrence of antibodies against hepatitis C virus (HCV) among alcoholics

Studies have shown that hepatitis C virus (HCV)-infected alcoholics have more severe biochemical and histological evidence of liver disease than anti-HCV-negative patients. One possible mechanism for the increased liver damage is that alcohol may have a stimulatory effect on HCV replication. This study was therefore carried out to investigate the seroprevalence of HCV virus among alcoholics. Two-hundred and seventy (270) alcoholics and fifty (50) control subjects at selected locations in Jos South local government area (LGA), of Plateau State were screened for HCV antibodies using grand rapid diagnostic test strip. Structured questionnaire was employed to obtain demographic data of studysubjects. Overall, the prevalence of HCV infection was found to be 45(16.7%) in response to alcoholics while the non-alcoholic (control) subjects recorded 3 (6.0%) positivity, [(x2 = 3.765); P > 0.05]. Genderconsideration showed that females subjects had a higher prevalence of 25 (9.3%) compared to males with 20 (7.4%) among the alcoholic subjects. The 19 – 30 years age group recorded the highestseroprevalence of 14 (5.2%) to the HCV, [(x2 = 4.757); P > 0.05], while no significant difference was observed among positive subjects screened for serum aminotranferase levels in relation to age and gender. Available evidence from this study indicates that alcoholic consumption is a strong determinant of HCV infection. Drastic measures at creating awareness and the need for routine screening among alcoholics should be given due consideration. However, future HCV studies need toquantify concurrent alcoholic consumption to further our understanding of the total burden of illness from alcohol associated HCV in the community.Keywords: Alcoholics, hepatitis c virus, occurrenc

Prevalence of Dermatophytes and other Associated Fungi among School Children

The study investigated the prevalence of dermatophytosis and associated non-dermatophytes among Islamiyya school children of ages 5 – 13 years old in Kano metropolis. A total of 100 samples were collected and 91 (91%) yielded positive to fungal growth from which 66 (72.5%) were identified from males and 25 (27.5%) from females school children respectively. Dermatophytes amounting to 53 (58.2%) in frequency were recorded out of which 39 (73.6%) were isolated from males and 14 (26.4%) on females. Non-dermatophytes were also more in males (27 isolates) than females which had 11. The etiological agents of dermatophycoses recorded in this study in descending order of prevalence are M. ferrugineum (15.4%), M. canis (15.4%), M. audounii (9.9%), T. concentricum (5.5%), T. verrucosum (3.3%), T. rubrum (3.3%), T. mentagrophyte (2.2%), T. tonsorans (1.1%) and T. schoenleini (1.1%). A. flavus (9.9%), A. niger (8.8%), Penicillium sp. (7.7%), Candida albicans (5.5%), Mucor sp. (4.4%), Trichoderma sp. (3.3%) and A. fumigatus (2.2%) constituted the non-dermatophytes associated with these cutaneous infections. Higher frequency of dermatophytosis occurred more in children with greater propensity for play, interaction with domestic animals and who lacked the luxury of school seats during classroom learnin

Global Economic Recession: The Place of Biotechnology

Human cytomegalovirus (CMV) is a leading cause of congenital infections worldwide Women infected for the first time during pregnancy are especially likely to transmit CMV to their fetuses and has been proposed as a risk factor for preterm birth. The seroprevalence of CMV in adults and the incidence of congenital CMV infection are highest in developing countries (1 to 5% of births) 90% of infected infants are asymptomatic at birth and are not recognized as at risk for CMV-associated infection. This study was carried out to determine the prevalence rate of CMV infection among pregnant women attending an antenatal clinic. In this study, Two-hundred and eighty eight (288) pregnant women were enrolled. Questionnaires were issued to volunteer subjects after due consent was sought, to determine demographic and other relevant data. 5mls of blood was collected by venous puncture from the antecubital fossa and dispensed into plain containers; sera were collected after centrifugation of the blood. Sera obtained were screened for the presence of CMV (IgM) antibodies using ELISA technique (Clinotec Laboratories Canada).Result showed that out of the 288 women tested, 54 (18.8%) were positive for CMV antibodies while 234 (81.2%) tested negative. With regards to age group distribution, women within 15 – 20 years had a prevalence rate of 4.5%, 21 – 30 years both had 3.5%, 31 – 35 had 3.1%, 36 – 40 years had 1.3% while 41 – 45 years had a prevalence rate of 2.8%, all the age groups had no statistical significant (P>0.05) result. With regards to trimester of the volunteer subjects screened, 1st, 2nd and 3rd trimester subjects recorded a prevalence rate of 3.1%, 9.4% and 6.2% respectively which was statistically significant (P0.05).Occupational status of subjects studied recorded no statistical significant (P0.05) result obtained showed that unemployed subjects recorded a prevalence of 5.6% compared to the self-employed with 4.9%, farmers recorded 3.8%, while students had a prevalence of 1.7% however subjects who are civil servants recorded a prevalence of 2.8%. Location of volunteer subjects studied showed that pregnant in rural areas had a prevalence rate of 12.2% while those living in urban areas recorded 6.6% prevalence without any statistical significant (P0.05).Records from this study indicates the of presence of CMV (Igm) antibodies amongst the subjects screened. Hence the need for early detection of the virus in pregnant women

Seroprevalence of Hepatitis B Surface Antigen (HBsAg) among Children of Primary School Age in a Community, North-Central, Nigeria

Globally, Hepatitis B Virus has been identified as one of the most common infectious diseases and a major public health problem.This study was therefore carried out to assess the prevalence of Hepatitis B virus infection among primary school children attending LGE primary school, Sabon Pegi, Kuru, Nigeria. Three hundred and sixty (360) blood samples were collected from the pupils and sera separated and analyzed for HBsAg using one step Hepatitis B surface antigen test strip. Of the 360 samples screened, 35 (9.7%) were sero-positive. Pupils within the age 7-9 years had the highest prevalence of 3.9%. Male subjects recorded a prevalence of 6.1% compared to 3.6% for females. Risk factors such as blood transfusion recorded 1.6%. Furthermore, family history of HBV infection accounted for 3.6%, while male subjects that had traditional method of circumcision recorded a high prevalence of 3.3%. Unfortunately, the prevalence of this ravaging infectious agent appears to be high amongst the subjects studied. It is strongly suggested that public awareness be accorded urgent attention while socioeconomic development in these areas be given priority as a measure to preventing further spread of this virus amongst children, particularly the school age group. Key words: Children, HBsAg, Primary school, Seroprevalenc

Delivery of thermostable Newcastle disease (ND) vaccine to chickens with broken millet grains as the vehicle

The efficacy of treated broken millet grains as a carrier for delivery of thermostable Newcastle disease (ND) vaccine HRV4 to free-range chickens in three locations was assessed by haemagglutinationinhibition (HI) test and challenge experiment. Out of 256 birds fed with first dose of the vaccine, 130 (50.8%) produced detectable HI antibody but only 16 (6.3%) attained serum antibody level of log2 3.0adjudged protective. From the locations, Igumale (74 birds), Kuru (88 birds) Riyom (94 birds), only 1 (1.4%), 8 (9.1%) and 7 (7.4%) attained log2 titre 3.0, respectively. A booster vaccine dose 2 weeks lateron 236 of the birds led to 126 (53.4%) attaining HI (log2) titre 3.0 [Igumale (63 birds), Kuru (86 birds) Riyom (87 birds) had 33 (53.5%), 46 (53.5%) and 42 (48.3%) respectively attaining log2 titres of 3.0]. Out of a total of 70 buy-back chickens challenged, 49 (70.0%) survived. The break down showed that from Igumale (20 birds), Kuru (25 birds) Riyom (25 birds), the survivors were 13 (65.0%), 19 (76.0%) and 17 (68.0%), respectively. Out of 28 unvaccinated control birds challenged, only 4 survived. The overall results showed that millet, if properly treated, could be a good vaccine carrier and that the method of vaccination was relatively efficacious.

Analysis of The Relationship Between Income Inequality snd Poverty Prevalence in Selected North Central States of Nigeria: 1991 – 2013

Poverty in Nigeria has been described as pervasive owing to the fact that the nation has witnessed a persistent increase in poverty level over the years despite various poverty alleviation programs. More so, it has been argued that income inequality is a manifestation as well as strong cause of poverty. The study therefore analyses the empirical relationship between income inequality and poverty prevalence among households in selected North Central States in Nigeria. This study employed survey method supported by time series data using regression analysis A representative sample of 600 respondents was planned for the survey in order to have at least 462 households responding. The result shows that dependency ratio, level of calorie intake, poverty per head counts are important factor influencing the level of poverty prevalence. Hence the study observes a substantial correlation between income inequality and poverty prevalence in the studied North Central Nigeria. The study therefore recommends a deliberate policy of reducing income inequality through equitable distribution of income and acceptable revenue sharing formula, need to campaign against large family size, providing subsidy and credit facilities for farmers and artisans true co-operatives, overhauling existing poverty alleviation programme and finally instituting good governance in every sphere of government activity which is a sine-qua-non for poverty reduction

Antibacterial and Phytochemical Potentials of Ficus capensis Leaf Extracts Against Some Pathogenic Bacteria

Natural products represent an alternative source of potent antimicrobial to combat the increasing antimicrobial resistance (AMR) to synthetic drugs. Plants in particular contain metabolites which have been widely employed in traditional settings to treat ailment. However, there is a need for scientific knowledge on their bioactivity. This study is aimed at elucidating the phytochemicals, and antibacterial activity of Fiscus capensis. The leaves of F. capensis were pulverized and extracted successively using n-hexane, acetone, methanol and distilled water. The plant extracts were evaluated for their antibacterial activity against selected Gram-positive and Gram-negative bacteria (Salmonella Typhi, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis, Escherichia coli, and Klebsiella sp.) using the agar-well diffusion technique. The minimum inhibitory concentrations (MIC) of the plant extracts were established using the microbroth dilution technique. The phytochemical analysis showed the presence of alkaloids in all extracts. Saponins, phenols, terpenoids and tannins were present in all extracts except n-hexane extract. The antimicrobial studies showed varying levels of activity, with acetone extract having the highest activity against S. aureus and S. Typhi with MIC of 6.25 mg/mL. Methanol had an MIC activity of 12.5 mg/mL against E.coli. While some prior studies reported no activity of methanol extract against S. Typhi, our finding showed that methanol extract of F. capensis exhibited antimicrobial activity against S. Typhi due to the extraction process. Our study concludes that the overall antimicrobial activity of the crude extract of F. capensis leaf provided evidence that future antimicrobial agents could be isolated from this plant leaf

Studies on the Serological Markers of Hepatitis B Virus Infection among Children in Riyom LGA, North Central Nigeria

Background: Globally, hepatitis B virus (HBV) infection has been identified as one of the most common infectious diseases of major health concern. This study was conducted to assess the prevalence of Hepatitis B virus infection among Children in selected communities at Riyom L.G.A. of Plateau State Nigeria. Methodology: Two hundred (200) sera samples were collected from Pupils attending Primary Schools at three locations of study and analyzed using the HBs Ag Monolisa ELISA kit and the HBV-5 panel test for the qualitative assessment of the markers of hepatitis B virus infection in human serum, plasma and whole blood. Result: Overall result from the total samples assayed showed that, 58(29.0%) were seropositive, [{P value of 0.020}: P 0.05]. Gender consideration of subjects screened showed that male subjects had a prevalence of 19.0% compared to 10.0% for Females [{P value of 0.0435}: P 0.05]. while subjects with traditional method of circumcision recorded a higher prevalence of 9.5% [{P value of 0.3120}:P< 0.05].Considering markers for HBV infection, findings showed that the highest rate of positivity recorded with the HBsAg showed 25% among children screened, HBeAg recorded 4.0%. Anti-HBs which indicate antibody to the HBsAg showed 35(17.5%) positivity while, Anti-HBe positivity recorded 15.0%.Similarly, Anti-HBc Positivity showed a record of 13.5% positivity. Conclusion: The result obtained from this study showed a higher prevalence of the Hepatitis B Virus at our locations of study compared to similar studies conducted earlier within our location of study. It is strongly suggested that accurate diagnosis with effective screening of pregnant mothers be intensified, while the need for timely vaccination of children at risk be promptly embarked upon

In vitro antimicrobial appraisal of the potentials of Morinda lucida against some selected bacteria

The bioactive compounds from plant extract represent a potent alternative to combating the increasing antimicrobial resistance (AMR) to synthetic drugs. This study aimed to investigate the phytochemical, and antibacterial activities of Morinda lucida. Leaves of M. lucida was extracted successively using n-hexane, acetone, methanol and distilled water. The crude plant extracts were evaluated for their antibacterial activity against pathogens found in food and other sources such as Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella enterica serovar Typhi, Escherichia coli, and Klebsiella spp. using the agar well diffusion technique. Minimum inhibitory concentration (MIC) was carried out using the microbroth dilution technique. The phytochemical analysis showed the presence of alkaloids and sterols in all extracts. Flavonoid was only present in the n-Hexane extract. The result showed that n-Hexane extract had the widest zone of inhibition against P. aeruginosa - 13.67 mm (12.5 mg/mL MIC), B. subtilis - 15 mm (12.5 mg/mL MIC), while acetone extract was most active against S. enterica ser. Typhi - 24.67 mm (6.25 mg/mL MIC), S. aureus - 24.83 mm (3.13 mg/mL MIC), E. coli - 13.33 mm (1.56 mg/mL MIC) and Klebsiella spp. - 18.33 mm (12.5 mg/mL MIC). These findings indicated that n-Hexane and acetone extract of M. lucida exhibited significant antimicrobial activity. Therefore, further research should be carried out to isolate the bioactive compounds with potentials in developing new drug leads against drug-resistant microbial strains

Detection of Hepatitis C Virus (HCV) antibodies among HIV Seropositive women attending a Rehabilitation centre.

Co-infection with human immunodeficiency Virus HIV and (HCV) is becoming a major global problem, leading to increased morbidity and mortality in both developed and developing countries. This research hence examines the risk factors and transmission of HIV and HCV co-infection. Two hundred and ninety (290) subjects were screened, with HCV global immunochromatographic test kit. Possible risk factors to co-infectious status of subject were determined using a well-structured questionnaire. Out of the 290 sera tested, 25 (8.6%) were positive for HCV antibodies. Considering Age of subjects screened, females aged 11-20 years recorded a high positivity of 3.1 %,( X2 = 2.755, P-value = 0.839; P>0.05).Marital status of subjects showed that single subjects recorded 13(4.5%), (X2 = 0.679,P-value = 0.712 ; P > 0.05)positivity compared to married subjects with 4.1%. There were no significant correlations between HCV infection with Age and Marital Status; P - values = 0.839 and 0.712 respectively (i.e P > 0.05). Significant correlation was found between HCV antibodies and educational status, (Value x2 = 7.957,P-value = 0.047; P < 0.05).However, Volunteers with secondary school level of education recorded 10(3.4%) positivity. The result obtained showed that Seroprevalence to HCV antibodies in this study was high, hence the need for its early diagnosis among HIV patients is strongly advocated to reduce the risk of further complications among these subjects
