Aims: Preterm premature rupture of membrane (PPROM) is usually associated with maternal vaginal colonization of Group B Streptococci (GBS). However, there are reports on isolation of Acinetobacter baumannii in PPROM cases. In order to ascertain A. baumannii's role in PPROM, we determine the colonization of A. baumannii and other common vaginal tract flora, i.e. GBS and Candida albicans, in women with PPROM, and compared them to those with normal labor at term (NLT). The transmissibility of the organisms to their babies was also investigated. Methodology and results: A total of 218 high vaginal swabs from 108 and 100 women with PPROM and NLT respectively were collected. The transmission of these organisms to their 215 babies was determined by swabbing the ears and axillae. These were cultured for isolation of A. baumannii, GBS and C. albicans. Results showed that mothers with PPROM were predominantly colonized with GBS (32.4%), followed by C. albicans (19.4%) and A. baumannii (7.4%), compared to 10.9%, 17.3% and 7.2% respectively, in women with NLT. Between 34 to 50% of the babies of mothers with PPROM acquired the organisms, with GBS being the most significantly (p=0.000) transferred compared to other organisms. Coexistence of A. baumannii with either GBS or C. albicans, or both, did not enhance the occurrence of PPROM. Conclusion, significance and impact of study: Colonization of A. baumannii in vaginal tract of pregnant women does not increase the possibility of PPROM, as compared to GBS.
Background: Hepatitis B virus (HBV) infection remains a worldwide healthcare concern, exceeding tuberculosis and HIV infection especially in developing countries. Endemic countries including Thailand, Indonesia and Philippines recorded of having prevalence rate of HBV infection ranging from 8% to16%. While Malaysia was estimated having 4.7% prevalence rate of HBV infection, yet the rate was mainly contributed by the major ethnics (Malay, Chinese and Indian) population, excluding aborigines (Orang Asli). This is due to lacking of data for HBV infection in this population. Thus, this study aimed to ascertain the epidemiological characteristics with prevalence rate of HBV infection among the Orang Asli, Negrito sub-tribe in Peninsular, Malaysia. The Negrito sub-tribe was chosen as they are the earliest inhabitants and the least population.Methods & Materials: A total of 150 subjects were recruited from five different Negrito settlements. A sociodemographic details and clinical history were taken with physical examination performed in all subjects. Five milliliters of whole blood was collected from all subjects and sera were tested for hepatitis B surface antigen (HBsAg) evaluation using an electrochemiluminescence immunoassay. All the epidemiological characteristics were analyzed using SPSS version 22.Results: Demographic profiles demonstrated 77% of infected subjects were more than 30 years of age, with infected male to female ratio of 2:1. The most possible route of HBV transmission of the infected subjects were mainly vertical or perinatal transmission (n = 13) with tattooing and body piercing (n = 6). Serological evaluation revealed that 13 subjects were reactive towards HBsAg test, which in turn gave the seroprevalence rate of 14.0% (95% CI: 7.0-21.0%). This finding demonstrated that the seroprevalence rate of HBV infection amongst aborigines in Malaysia was almost three times higher than the established rate, in keeping with previous studies performed on indigenous population elsewhere. Conclusion:In conclusion the prevalence rate of HBV infection was high amongst Orang Asli. Hence this epidemiological spectrum serves as preliminary data of HBV infection amongst Orang Asli in Malaysia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
