This study was conducted to determine the prevalence of bacterial vaginosis among women of age 20 to 59 years at Sarawak General Hospital by examining the conventional Pap smear. The prevalence of this infection was studied among the five main ethnic groups comprising the Iban, Chinese, Malay, Bidayuh and Orang Ulu. Microscopic screening of 300 conventional Pap smears which had been processed and stained with the Papanicolaou staining method was conducted. Based on the information provided in the Pap smear screening form, the clinical manifestations were observed which may provide some indications on the type of infection. The details of the clinical manifestations were very important because in an infection or inflammation, Pap smears would usually demonstrate changes on the cyto-morphology of the epithelial cells. The age factor among the different ethnics also played important role in the assessment of the infection frequency. Bacterial vaginosis was detected in 79.7% (239/300) of cases. The infection occurred in all ethnic groups and the infections were more frequently seen among the 20 to 39 years age group. Majority of the cases (93.9%) presented with clinical signs and symptoms. The results of this study revealed the importance of undergoing a Pap smear screening for bacterial vaginosis detection besides screening for the early detection of cervical cancer

This study was conducted to determine the prevalence of candidiasis among women of 20 to 59 years of age at Sarawak General Hospital by examining the conventional Pap smear. The prevalence of this infection was studied among the five main ethnic groups comprising of Iban, Chinese, Malay, Bidayuh and Orang Ulu. Microscopic screening of 300 conventional Pap smears which had been processed and stained with the Papanicolaou staining method was conducted. Based on the information provided in the Pap smear screening form, the clinical manifestations were observed which may provide some indications on the type of infection. The details of the clinical manifestations were very important because in an infection or inflammation, Pap smears would usually demonstrate the cyto-morphological changes of the epithelial cells. The age factor among the different ethnics also plays important role in the assessment of the infection frequency. Candida sp. was detected in 12.7% of the specimens. The infection occurred in all ethnic groups as well as in all age groups. All cases presented with clinical signs and symptoms. The results of this study revealed the importance of undergoing Pap smear screening for candidiasis detection besides screening for the early detection of cervical cancer

A study on the isolation and identification of bacterial flora from hot spring was carried out using water from Bentong hot spring in Pahang. In general most of the bacteria identified from the hot springs were from Bacillus sp. This was due to its ability to adapt to high temperature mainly by forming endospore. The objective of this study was to identify bacteria other than Bacillus that were able to survive in hot springs. Three hot spring pools were identified (A,B and C) with temperatures ranging from 36°C to 52°C and pH values between 7.88-8.65. This study has succesfully isolated two species of Gram positive cocci and three species of Gram negative bacilli. The two Gram positives were Streptococcus sp. and Staphylococcus sp. The three species of Gram negative rods were unidentified and were denoted as X, XI and XII.

The two Gram positives wereStreptococcus sp. and Staphylococcus sp. The three species of Gram negative rods were identified as Pseudomonas sp.,Klebsiella sp. and Proteus sp. In conclusion, non-sporulating species of bacteria other than Bacillus sp. have adaptedto survive in hot spring

Pesticides and chemical fertilizers are widely used in agriculture to increase crop productivity among farmers.However, exposure to pesticides will give potential risk to human health. The aim of this study was to analyze thefrequency of micronucleus (MN) and binucleus (BNu) formation in buccal cells from farmers who were exposedto pesticides using the MN assay. Buccal swabs were collected from the farmers in Tanjung Karang (n = 32) andKelantan (n = 43) using wooden tongue depressor. A structured questionnaire was used to obtain demographic dataof the farmers. Cytogenetic analysis was carried out by Acridin Orange (AO) staining 0.0025% (w/v). The frequencyof MN and BNu as the biomarkers for cytogenetic damage was observed by using a fluorescence microscope.Comparison of frequency of MN and BNu is conducted in two areas namely Tanjung Karang, Selangor and Kelantanbecause of the agricultural activity and the type of pesticides used are different. Results showed that the frequencies of bothMN and BNu among farmers in Tanjung Karang were significantly higher (p < 0.05) compared to farmers in Kelantan.Meanwhile, for the socio-demographic factors (age, smoking status, working period), MN and BNu frequencies amongfarmers in Tanjung Karang were also significantly higher (p < 0.05) as compared to farmers in Kelantan. While in theaspect of pesticide exposure, the frequencies of MN and BNu showed no significant difference between the frequency ofpesticide spraying (p > 0.05) and the practices of PPE (Personal Protective Equipment) (p > 0.05). This may suggeststhat cytogenetic changes were not influenced by these factors. In addition, correlation study shows positive correlationbetween the frequency of MN with the pesticide exposure of farmers in Tanjung Karang (p > 0.05, r = 0.015) and Kelantan(p > 0.05, r = 0.0158). Besides, the frequency of BNu also has a positive correlation with the pesticide exposure amongfarmers in Tanjung Karang (p > 0.05, r = 0.036) and farmers in Kelantan (p > 0.05, r = 0.013). Hence, this present study demonstrated that exposure to pesticides increasedthe formation of MN and BNu among farmers and theprolonged use of pesticides may induce genotoxicity andDNA damage to human.
