Staphylococcus aureus (S. aureus) is one of the earliest pathogens involved in human infections, responsible for a large variety of pathologies. Methicillin was the first antibiotic used to treat infections due to S. aureus but infections due to Methicillin resistant Staphylococcus aureus (MRSA) originated from hospital settings. Later, severe infections due to MRSA without any contact with the hospital environment or health care workers arose. Prevalence of MRSA has shown an alarming increase worldover including Cameroon. This Cross-sectional study was designed to evaluate the occurrence of MRSA infections in five different, most frequented Hospitals in northern Cameroon. Socio demographic data was recorded through questionnaire and different clinical specimens were collected for bacterial isolation. Identification of S. aureus was confirmed via 16s rRNA amplification using S. aureus specific primers. Molecular characterisation was performed through mecA gene, Luk PV gene screening and SCCmec typing. A total of 380 S. aureus clinical isolates were obtained of which 202 (53.2%) were nonduplicate multidrug resistant isolates containing, 45.5% MRSA. Higher number of MRSA was isolated from pus (30.4%) followed by blood culture (18.5%), and urine (17.4%). Patients aged 15 to 30 years presented high prevalence of MRSA (30.4%). Majority isolates (97.8%) carried the mecA gene, PVL toxin screening indicated 53.3% isolates carried the lukPV gene. Based on PVL detection and clinical history, CA-MRSA represented 53.3% of isolates. SCCmec typing showed that the Type IV was most prevalent (29.3%), followed by type I (23.9%). Amongst MRSA isolates high resistance to penicillin (91.1%), cotrimoxazole (86.7%), tetracycline (72.2%), and ofloxacin (70.0%) was detected. Meanwhile, rifampicin, fusidic acid, lincomycin and minocycline presented high efficacy in bacterial control. This study revealed a high prevalence of MRSA among infections due to S. aureus in Northern Cameroon. All MRSA recorded were multidrug resistant and the prevalence of CA MRSA are subsequently increasing, among population.
ObjectiveThis study was performed in order to fill the gap of knowledge regarding sero-epidemiology of hepatitis B virus (HBV) amongst Human Immunodeficiency virus (HIV)-infected patients and to assess the risk factors associated with HBV co-infection in a rural locality of Cameroon. A retrospective and cross-sectional study was carried out from January 2008 to April 2014 within the Mfou District Hospital. Naive HIV-infected patients were enrolled in the study and tested for hepatitis B surface antigen (HBsAg). Preliminary pre-therapeutic data essential for follow-up was collected from the participants.ResultsOverall, the sample size was constituted of 712 HIV-infected patients. The prevalence of HBsAg was 8.99%. A significant difference was observed in the proportion of HBsAg positive subjects with respect to the year of inclusion; higher proportions were observed between 2011 and 2014 (P-value = 0.007). Majority of HBV co-infected participants had severe immuno-suppression with CD4 counts lower than 100 cells/µL as compared to HIV mono-infected population but the difference was not statistically significant. Our results confirm the high prevalence for HBV infection among HIV-infected patients in the Mfou District Hospital. These findings will enable stake holders to be better armed in the elimination of viral hepatitis as a public health problem.
IntroductionLes infections sexuellement transmissibles sévissent toujours dans les pays en voie de développement et particulièrement au Cameroun. Le but de notre étude est de déterminer la distribution des infections sexuellement transmissibles suivantes: l’hépatite virale B, le Chlamydia trachomatis et de la syphilis dans une population de femmes venant consulter spontanément à l’Hôpital de District de Nkoldongo à Yaoundé, d’évaluer d’éventuelles coïnfections entre ces trois affections et de ressortir les connaissances de ces femmes sur leur mode de transmission sexuelle.MéthodesNotre étude prospective et descriptive a porté sur 182 femmes dont l’âge variait entre 18 et 48 ans. Les femmes ont été testées sérologiquement pour le Chlamydia trachomatis par une méthode ELISA (kit des laboratoires General Biological Corp). L’hépatite virale B a été dépistée par une méthode immunochromatographique (kit des laboratoires Human) et la syphilis par une méthode d’agglutination en ce qui concerne le RPR (Kit des laboratoires Biocentric) et le TPHA (kit des laboratoires Human).RésultatsNos résultats ont montré que: la distribution du Chlamydia trachomatis, de l’hépatite virale B et la syphilis a été respectivement de 22,52%, 4,39%, 0,54%.De plus, nous avons observé une coinfection Chlamydia trachomatis hépatite virale B avec un taux de 2,74%. Par ailleurs la réinfection au Chlamydia trachomatis a été rencontrée dans 4,94% de cas. S’agissant du mode de transmission de ces affections 67,57% et 70,87% de femmes ne connaissaient pas la voie de transmission sexuelle pour le Chlamydia trachomatis et pour l’hépatite virale B respectivement, tandis que 91,2 % des femmes connaissaient la voie de transmission sexuelle pour la syphilis.ConclusionLe diagnostic d’une infection à Chlamydia trachomatis chez une patiente doit susciter le dépistage de l’hépatite virale B.IntroductionSexually transmitted infections are still frequent in developing countries and particularly in Cameroon. The aim of this study was to determine the distribution of the following sexually transmitted infections: viral hepatitis B, Chlamydia trachomatis and syphilis in a population of women spontaneously visiting the Nkoldongo District Hospital in Yaoundé as well as to evaluate possible co-infections among these three conditions and to bring out women’s prior knowledge of how sexual transmission occurs.MethodsWe conducted a prospective and descriptive study including 182 women aged between 18 and 48 years. These women underwent serologic testing for Chlamydia trachomatis with ELISA (General Biological Corp laboratory test kit. Hepatitis B virus was detected using immunochromatographic method (Human laboratory kit) while syphilis was detected using RPR agglutination (Biocentric Laboratories kit )and TPHA agglutination (Human laboratory kit) method.ResultsOur results showed that the distribution of Chlamydia trachomatis, viral hepatitis B and syphilis was 22.52%, 4.39%, 0.54% respectively. Moreover, we reported a Chlamydia trachomatis and Viral hepatitis B coinfectio...
