Assessment of the Microbial Quality of Air in Some Science Laboratories of Bayero University Kano Old Campus-Nigeria

Abba Mas’ud Alfanda1*, Murjanatu Mas’ud2, Fatima Mas’ud3

Science laboratories are dynamic environments affected by both microbial load and indoor airquality from the occupants’ activities. Management atBayero university Kano faces a challenge when it comesto maintaining satisfactory air quality in thelaboratories. Regular monitoring is, therefore, necessary to evaluate air control effectiveness and to detect the irregular introduction of airbornemicroorganisms via occupants, and orthe transmission through equipment and laboratory materials. The principal aim of thisstudy is to assess the microbial quality of the air in someselected laboratories at the oldcampus of Bayero university Kano by measuring indoor bacterial and fungal loads. Samples were collected from eight selected laboratories by setting exposed plates for 10 minutes. Bacteria were then incubated at 37°C for 24 hours, and fungi at 28°C for 1-5 days. Based on the results, it is evident that penicilium (20.9%) and Streptococcus pneumoniae (34.1%) were the most prevalent species in all the case study laboratories. Due to this, pneumonia related diseases have a high risk ofspreading. There were high to very high levels of bacterial and fungal contamination in all eight laboratories. A good personnel hygiene practice can be utilized to reduce the microbial burden within laboratory environments
