Objective: A study on indoor air play important roles in human health by polluted indoor labrotory and causes some diseases such as infections skin, eyes, respiratory system , allergy and biotoxicity. Air is made up of enormous of microorganisms mainly bacteria. Their estimation is important as an indication of cleanliness of any particular environment. The presence both bacteria and fungi in indoor air is problem of health protection due to a long time period that workers and students stay indoors. Determination of level microbial pollution indoors is necessary to assess the health hazard for indoor air quality control. This study provides information on microbial contamination level of indoor air of biological labrotary was estimated. Material and Methods: Collected air samples from seven bio-laboratories and low, up corridors locations during April-June 2019. Air samples were taken three months : in the in the afternoon. Results: The higher of percentage of isolated airborne bacteria Staphylococcus aureus and Staphylococcus epidermis, it was 58.57% and 26.84% for all biological laboratories respectively at study location, while the lowest percentage were Klebsiella sp. and Protus sp., it was 11.98% and 4.29% for all biological laboratories, respectively. Conclusion: It is concluded from the current study that is advisable that estimate to check microorganisms loads in Laboratories and prevent their increase and spread

In Malaysia, Entada spiralis Ridl. from Leguminoceae family grows wildly and the scientific study of it has not been explored deeply. Entada spiralis Ridl. is a liana or woody climber plant which is locally known as "akarbeluru" or "Sintok". This study is performed to evaluate the antibacterial activity of Sintok extract from the stem bark of Entada spiralis against skin bacteria infections by the disc diffusion method. Two types of skin bacteria known as Staphylococcus aureus and Streptococcus pyogenes were selected and tested against the water extracted Sintok. Sintok concentration of 1600mg/ml gave the highest inhibition zone diameter against Streptococcus pyogene rather than Staphylococcus aureus with a diameter of 25.5 mm and 18. mm, respectively. This study indicates clear evidence supporting the traditional use of Entada spiralis in treating skin infections related to bacteria
