The investigation was conducted with an objective to study the microflora of the air in the operation theatres and effectiveness of formaldehyde fumigation. Fumigation with formaldehyde (1:1 dilution with water) was done in each operation theatre for 30 min and the samples were taken from small animl and large animal operation theatres. Micrococcus sp. predominated the air microflora in both operation theatres followed by Bacillus sp., Corynebacterium sp. and Gram negative bacteria. With the above method of fumigation, there was significant reduction in bacterial load of air. In large animal operation theatre, the reduction was 37.4–43.4%, whereas the reduction in small animal operation theatre was 66.6–66.9%.
