Antimicrobials have proven to be important for sustainable livestock production by their use as growth promoters and in the control of animal infections. However, injudicious use of antimicrobials could accelerate the emergence and spread of resistant bacterial strains with attendant socioeconomic and public health issues. This work assessed antimicrobial usage in animal production with emphasis on usage and practices by livestock producers in Oyo and Kaduna States of Nigeria. Data on antimicrobial usage were collected through interviews, questionnaire and focus group discussions. Four hundred and fifty-four farmers in 11 communities within 11 Local Government Areas of Oyo and Kaduna States of Nigeria were sampled in a multi-stage sampling procedure. The study showed that antimicrobial agents were widely distributed, readily accessible and commonly used in animal production. Fluoroquinolones and other critically important antimicrobials for human medicine were widely used in animals as prophylactics. Potentially harmful antimicrobials including furazolidones and chloramphenicol already banned for use in humans and animals were freely marketed and used in livestock production. Most of the respondents believed that veterinarians should be responsible for the administration of antimicrobials to animals, but in practice, they buy and administer antimicrobials without consulting veterinary professionals. It was observed that the ready availability of antimicrobial agents promoted the use of antimicrobials in livestock production and may encourage non-adherence to hygienic principles and management laxity in farm operations. The non-involvement of veterinary professionals and laboratory investigations in disease diagnosis prior to antimicrobial use could lead to improper usage that contribute to the development of antimicrobial resistance in bacterial strains. Responsible antimicrobial stewardship and strict regulations are vital to prolonging the benefits derivable from the use of antimicrobials.

Code Number: rh03007 ABSTRACT Eight hundred and ninety six adolescents aged 11-25 years were recruited into this study using a multi-stage random sampling method. Overall, about 33% of them had already had first sexual experience but more males than females reported having experienced first sexual encounter. Only 3.6% of the respondents were married. One half of the sexually experienced adolescents had more than one sexual partner at the time of the study. Majority of the respondents (91.9%) had heard about HIV/AIDS and at least a STD. A wide disparity was found in knowledge and use of the contraceptive methods studied, ranging from 41.9% to 63.8% for knowledge and from 0.7% to 12.5% for use. Knowledge and use of condom was highest. For prevention of HIV/AIDS, more males than females thought condom was useful. More Gwari and Hausa respondents claimed that they did not use any family planning method during their first sexual relationship than Yoruba and Igbo respondents. There is need for reproductive health programmes to intensify efforts towards improving adolescents' attitudes to risky sexual behaviours and motivate them to undertake behaviours that would limit such risks. Les comportements reproductifs, sexuels et contraceptifs des adolescents dans l'Etat de Niger au Nigéria. Huit cent quatre-vingt-seize adolescents âgés de 11-25 ans ont été recrutés pour faire partie de cette étude qui a été effectué à l'aide de la méthode d'échantillonnage à multiples étapes. D'ensemble, environ 33% d'eux avaient déjà eu un premier rapport sexuel, mais il y avaient plus des hommes qui avaient déclaré avoir eu une première expérience du rapport sexuel. Seuls 3,6% des interrogés étaient mariés. La moitié des adolescents qui étaient sexuellement expérimentés avaient plus d'un partenaire sexuel au moment où l'étude a été menée. La majorité des interrogés (91,9%) étaient au courant de l'existence du VIH/SIDA et au moins d'une MST. Il y avait un grand écart entre la connaissance et l'emploi des méthodes contraceptives, qui allait de 41,9% jusqu'à 63,8% pour la connaissance et de 0,7% à 12,5% pour l'emploi. La connaissance et l'emploi du préservatif étaient les plus élevés. Quant à la prévention du VIH/SIDA, il y avait plus des hommes que des femmes qui ont pensé que le préservatif était utile. Plus des interrogés d'origine gwari et haoussa que les interrogés d'origine yorubas et ibo ont déclaré qu'ils n'avaient pas employé la méthode de planification familiale au cours de leurs premiers rapports sexuels. Il faut que les programmes de la santé reproductive intensifient leurs efforts vers l'amélioration des attitudes des adolescents envers les comportements sexuels à risque et de les motiver de façon à ce qu'ils puissent se comporter de manière à réduire de tels risques.

BackgroundThere is a dearth of information on the health of pastoral Fulani children living in southwestern Nigeria. These are fully settled pastoralists whose economy are centred on cattle and farming. In other to monitor and plan appropriate nutritional intervention for their children, a cross-sectional study was carried out to determine the prevalence of malnutrition of pastoral Fulani children.FindingsFulani's children aged 6 months to 15 years, living in 61 settlements in Kwara, Ogun and Oyo States in Southwestern Nigeria participated in the study. Heights and weights of 164 girls and 167 boys were measured. Their anthropometric indices, height-for-age (HA), weight-for-height (WH), and weight-for-age (WA) Z-scores determined. The prevalence of stunting (HAZ < -2), wasting (WHZ < -2) and underweight (WAZ < -2) was 38.7%, 13.6%, and 38.7%, respectively when compared to the reference NCHS/WHO standard used for defining stunting, wasting and underweight. Boys were more malnourished than the girls were, but this was not significant (stunting: χ2 = 0.36; df = 1; P = 0.54); (underweight: χ2 = 1.10; df = 1; P = 0.29); and (wasting: χ2 = 0.00; df = 1; P = 0.98) The mean of Z-scores of Height-for-age, Weight-for-age and Weight-for-height in children were -1.502, -1.634 and -0.931 respectively. The SD was 1.52, 1.09 and 1.20 respectively. Using WHO Malnutrition Classification systems, 38.7% of the children were found to be malnourished.ConclusionThese results indicate high prevalence of malnutrition among settled pastoral Fulani children, possibly due to changes in food habits and lifestyle occasion by the transition from nomadic to sedentary living. We suggest the inclusion of Fulani's settlements in nutritional intervention for these areas.

Bovine brucellosis is endemic in Nigeria; however, limited data exist on nationwide studies and risk factors associated with the disease. Using a cross-sectional sero-epidemiological survey, we determined the prevalence of and risk factors for brucellosis in slaughtered cattle in three geographical regions of Nigeria. Serum samples from randomly selected unvaccinated cattle slaughtered over a period of 3 years (between December 2010 and September 2013) from northern, southern and south-western Nigeria were tested for antibodies to Brucella abortus using the Rose Bengal test. Data associated with risk factors of brucellosis were analysed by Stata Version 12. In all, 8105 cattle were screened. An overall seroprevalence of 3.9% (315/8105) was recorded by the Rose Bengal test, with 3.8%, 3.4% and 4.0% from the northern, southern and south-western regions, respectively. Bivariate analysis showed that cattle screened in northern Nigeria were less likely to be seropositive for antibodies to Brucella spp. than those from south-western Nigeria (odds ratio = 0.94; 95% confidence interval: 0.73–1.22). However, logistic regression analysis revealed that breed ( p = 0.04) and sex ( p £ 0.0001) of cattle were statistically significant for seropositivity to Brucella spp. The study found that brucellosis was endemic at a low prevalence among slaughtered cattle in Nigeria, with sex and breed of cattle being significant risk factors. Considering the public health implications of brucellosis, we advocate coordinated surveillance for the disease among diverse cattle populations in Nigeria, as is carried out in most developed countries.
