Abstract: This study was designed to ascertain if the rabies virus antigen found among apparently healthy dogs were viable and to which genotype they belong. One hundred and fifty two dog heads were randomly collected from markets and restaurants where dogs are slaughtered and consumed as delicacy in Enugu State, Nigeria. The brain samples from the heads were examined for the presence of rabies virus antigen by direct fluorescent antibody technique, while positive ones were isolated by the mice inoculation test. Viral genotypes of the positive samples were determined by reverse transcriptase polymerase chain reaction and sequencing. Out of the one hundred and fifty two dog brain samples examined, six (4) were positive by direct fluorescent antibody technique and mice inoculation test. All the isolates belong to genotype 1 rabies virus. The result of this study showed that some of the apparently healthy dogs slaughtered for meat in Enugu state have classical rabies virus and possibly shed the virus in their saliva without showing obvious clinical signs. This has a serious public health implication and thus calls for a re-evaluation of rabies endemicity in Nigeria.[...] Read More.

Abstract: Obesity and overweight are considered the most rapidly growing form of malnutrition in Saudi Arabia. The aim of this study was to determine the prevalence and some risk factors of obesity and overweight among Taif university students. A cross-sectional approach was conducted and 1473 male students were selected. A self administered questionnaire included socio-demographic data, different forms of activities, sedentary behaviors, smoking, dietary habits and family history was used for data collection. Body mass index was calculated and categorized according to WHO classification. Prevalence of obesity and overweight were 16.1% and 28.5%, respectively. However, higher prevalence was observed in older students (p=0.00). Higher prevalence was found among students with high family incomemonth (p=0.02), less daily active (p=0.00) and physically inactive students (p=0.03). Moreover, prevalence was more among students consuming non-healthy diet (p=0.00), sleeping less than 8 hoursday (p=0.00) and with family history of obesity (p=0.00). Prevalence was significant among students with highly educated fathers (p=0.01) and low educated mothers (p=0.01). In conclusion, high prevalence of obesity and overweight were recorded among University students. Further studies of large samples representing both sexes as well as health education program on obesity and overweight are highly recommended to the students and their families.[...] Read More.

Abstract: Refractive error is the most common cause of vision impairment among children, and schools with long period of engagement in vision screening were effective in detecting undiagnosed cases. The aim of this study was to assess the prevalence of refractive error among female primary school children. A cross-sectional study was carried out from February to March 2013 using structured questionnaire and visual examination. Visual acuity of 324 students was assessed using the Snellen’s chart. Those with VA 6/12 or less with or without correction in one or both eyes were examined by pinhole test, and an improvement of the VA with pinhole was considered refractive error. The prevalence of RE was 16.4%, and a significant relationship was found between having RE in one side and having a family history of wearing glasses, higher class grades, poor school performance, watching television at a distance less than 3 meters, using internet/ TV daily for more than 3 hours, and indulgence in computer or video games in the other side. The study showed that even in economically advantaged societies, refractive errors can go undetected in children. That is why integration of vision screening for refractive errors into KSA school health programmes is necessary.[...] Read More.

Abstract: This study was carried out to isolate and characterize the causative agent of fowl typhoid in some outbreaks in chickens. Seventy isolates of Salmonella Gallinarum were recovered from culturing visceral organs and cloacal swabs obtained from 30 different outbreaks affecting 29 poultry farms in 8 parts of Kaduna State, Nigeria within two years, February, 2011 – January, 2013. Real-Time Polymerase Chain Reaction was carried out using primers targeting invA gene which confirmed all isolates as Salmonella. Multiplex PCR was carried out to target glgC and speC genes in order to differentiate between biovars Gallinarum and Pullorum. Results showed that all the isolates possessed both genes, confirming that they were biovar Gallinarum. Ten isolates were selected and characterized by XbaI - Pulsed-Field Gel Electrophoresis (PFGE). The selected isolates represented farms in various parts of the three Local Government Areas (LGAs) where outbreaks occurred. Out of these ten isolates, six isolates were chosen from 55 isolates recovered from 22 affected farms in Sabon Gari LGA. Three isolates were chosen from 9 isolates recovered from 5 affected farms in Kaduna North LGA; while 1 isolate was chosen from 5 isolates recovered from the 2 farms affected in Kaduna South LGA. The PFGE profiles showed >78% degree of relatedness among Salmonella isolates. This study provides information that the poultry industry in Kaduna State, Nigeria is still plagued with outbreaks of fowl typhoid caused by closely related Salmonella Gallinarum which were isolated.[...] Read More.

Abstract: Acute Flaccid Paralysis (AFP) surveillance was adopted by World Health Organization (WHO) following the World Health Assembly (WHA) Resolutions in May 1988, to monitor progress towards poliomyelitis eradication in all member countries. It was introduced in Zambia in 1993, but active AFP surveillance started in 1998. Since then, health workers collect AFP surveillance data, but there is no documented evidence of the review of the performance of the system and epidemiological analysis of the data. A retrospective descriptive analysis was conducted on secondary AFP surveillance data for the period 2000-2009, consisting of all children aged[...] Read More.

Abstract: Live bird markets (LBMs) are essential for marketing of poultry, but can be a hub for the rapid spread of diseases including avian influenza (AI). We assessed the status of biosecurity in 108 LBMs in 37 districts of Uganda. In all LBMs, carcasses were disposed of in the open and birds were introduced in the markets without initial quarantine. A high proportion of markets lacked a dedicated site for unloading of birds (86.1%) and a programme for disinfection (99.1%), had dirty feed/water troughs (93.5%), were accessed by stray animals (97.2%), and had sick and healthy birds (96.3%) or different bird species (86.1%) sold together. Differences in practices occurred among geographical regions and market location. Birds were more likely to be slaughtered in the open in urban compared to rural LBMs (OR=14.6, 95% CI: 1.50 - 142), while selling of un-caged birds was less likely in central compared to western region (OR=0.2, 95% CI: 0.04 - 0.17). Different poultry species confined in the same cage were more likely to be sold in urban (OR=22, 95% CI: 1.14 - 435) compared to rural markets. We conclude that LBMs in Uganda are a potential risk for spread of AI to poultry and humans.[...] Read More.

Abstract: There is need to continually monitor and document the trends of overweight and underweight in the public health context of developing nations so as to suitably adjust public health strategies and disease management approaches. This study reported the BMI trends of 2 different youth populations in southeast Nigeria. 2732 secondary school students were selected through a multi-stage sampling technique and their body mass indices obtained. The prevalence of overweight, obesity and underweight were determined using Body Mass Index (BMI). The findings were compared with the data of a cohort of medical school undergraduates (n=131). Approximately 75% and 66% respectively of secondary and tertiary students were underweight. The prevalence of overweight was 3% in secondary and 19% in tertiary student populations. Obesity was less than 1% in both groups. Only 21.99% and 14.52% respectively of the younger and older youth populations had normal BMI. The current mean prevalence of obesity among Nigeria youth populations was[...] Read More.

Abstract: A study was conducted to determine the occurrence of vancomycin resistant S. aureus (VRSA) in milk in Nigeria. Fourty seven S. aureus were isolated from the 372 milk samples examined, out of which 20 (5.4%) were vancomycin-resistant. Fifteen (4%) of the VRSA were isolated from raw milk, 4 (1.1%) from bulk milk and 1 (0.3%) from pasteurized milk. No significant difference (P > 0.05) between the occurrence among the study variables was observed, . No VRSA occurred in the yogurt and ‘kindirmo’ samples examined. The decrease in the occurrence of the pathogen from  raw milk to pasteurized milk and its absence in yogurt and ‘kidirmo’ suggest that pasteurization and fermentation may have eliminated most of the organisms. The resistance profiles of the VRSA isolates to other antibiotics showed high resistance to penicillin (100%), tetracycline (85%), amoxicillin (65%), methicillin (40%) and oxacillin (40%), but low to amikacin (5%) and sulphamethoxazole/trimethoprim (10%). None of the isolates were resistant to chloramphenicol and ciprofloxacin. The multiple antibiotic resistance index result revealed that 80% of the VRSA were resistant to 3 or more antibiotics. The presence of VRSA coupled with the multple resistance patterns of these isolates are of great concern and also of public health significance. Therefore more studies on the epidemiology of this pathogen in foods are required.[...] Read More.

Abstract: Alcohol has a strong effect on people and can cause major health problems, including liver cirrhosis and injuries in consumer’s bodies. In Cameroon, data on alcohol consumption levels as well as its influences on youth psychology and education are currently non-existing. The aim of this survey was to determine beer consumption patterns amongst students in higher institutions of learning in Buea, Cameroon, in relations to students’ lifestyles, health history and academic performances. Structured questionnaires were randomly administered to some 280 students. A total of 200 responses (males: 56.5%; females: 43.5%) were obtained from students who consume beer. Beer consumption practices were directly associated with students monthly pocket allowances. Averagely, students who drank beer consumed 1.7 L/day. This may partly justify the observed alcohol intoxication related symptoms including nausea, memory loss, accidents as revealed by survey findings. Generally, beer intake correlated negatively with student’s attitude toward their studies and positively with violence as well as nasty practices such as unconscious sexual behaviours; pointing at risk of HIV infections.  This preliminary survey has for the first time in Cameroon provided data on beer intake and its effects on student’s health, behaviours and attitude towards their education.[...] Read More.

Abstract: Young persons are disproportionately affected by the impact of HIV in Nigeria. This paper presents findings from an evaluation of a national youth HIV prevention program designed to determine the effects of HIV prevention intervention (HPI) on Youths on Compulsory National Service (YoCNS) and Adolescents in Secondary Schools (AiSS). Data were collected from 229 YoCNS who received training on HIV prevention and 231 of their counterparts who did not. Among AiSS, data were collected from 909 respondents who were trained as peer educators and among 1005 students who were not. Data were collected in six states namely Akwa-Ibom, Enugu, Gombe, Kaduna, Plateau and Osun using a questionnaire that explored knowledge on HIV and sexual behavior and supplemented by focus group discussions and in-depth interviews. Results show that both youths and students who received HPI reported superior knowledge on HIV/AIDS than their counterparts who did not. Students in the intervention sites also reported fewer numbers of multiple sexual partners (9.7%) compared to those in the comparison sites (15.4%). The qualitative data shows that the project had positive effects on both youths and students who received the intervention. Given these positive outcomes, it is recommended that the project should not only be sustained but expanded to reach adolescents who are out of school.[...] Read More.
