The specimens were examined for the presence of Trichomonas vaginalis using wet mount, Giemsa staining and cultured in Diamond's medium. Sociodemographic characteristics and gynaecological complaints were obtained in private using structured questionnaire applied by one investigator.Results: The median age was 32 years, with an interquartile interval of 9.96. Most of the subjects were Malays(76.9%) and the remaining were Chinese(15.1%), Indians(2.2%)and other ethnic groups(5.8%). One hundred and thirty eight(99.3%) of the women were married and 98.6% had less than 6 children. More than half(75.5%) of the women's last child birth was less than 6 years ago. Forty seven percent of them were involved in supporting administrative work and 64.7% of the women gave a history of previous or current vaginal discharge.Conclusions: The present study reported zero incidence rate of trichomoniasis. The low incidence rate was postulated due to all women who participated in this study were categorized into a low-risk group.展开更多

Methods: A total of 473 stool samples from the aborigines in Temerloh, Pahang, Malaysia were collected during wet(n=256) and dry seasons(n=217). Smear of all the PVA-preserved stool samples were subjected to Trichrome staining and microscopic examination under 1 000 伊magnification(Nikon eclipse E100) for the detection of G. lamblia. Positivity was recorded based on the presence of G. lamblia in trophozoite and/or cyst forms. Results: The prevalence of giardiasis was 12.10% and 8.29% during the wet and dry season, respectively. Age of less or equal to 15 years old and presence of other family members with G. lamblia infection were found to be the significant risk factors to acquire G. lamblia infections during both seasons. Untreated water supply was the significant risk factor of giardiasis during the dry season. This study highlighted the possibility of anthroponotic transmission of G. lamblia during both seasons and waterborne transmission during the dry season in the aboriginal community. Conclusions: This study suggests that seasonal variation plays an important role in the prevalence and risk factor of G. lamblia infection in the aboriginal community. Therefore, close contact with Giardia-infected family members and water-related activities or usage of untreated water must be avoided to reduce the burden of G. lamblia infection in this community.展开更多

Methods:This cross-sectional study was conducted among 253 participants aged between 1 and 85 years. Stool samples were examined using Wheatley's trichrome stain after in-vitro cultivation in Jones' medium to detect the presence of Blastocystis. Information pertaining to the demography,socioeconomic and environment were collected using pre-validated questionnaires. Results:The total prevalence of Blastocystis infection was 40.7%. The multiple logistic regression analysis revealed that age ≥15 years(OR = 2.72; 95%CI = 1.47-5.04) and presence of infected family members(OR = 8.56; 95%CI = 4.47-16.38) were the significant risk factors associated with blastocystosis in these communities. Conclusions:Blastocystosis is revealed through this study to be still prevalent among Orang Asli communities in rural Malaysia. The two main approaches that should be implemented by the public health authority in battling this infection would be the screening of other family members and giving treatment to the infected individuals. Moreover,it is imperative for health education on good personal and food hygiene practices are provided in order to reduce the morbidity and transmission of Blastocystis infection among the Orang Asli in their communities meaningfully.展开更多
