Indeed, the draining rack exhibited higher levels of heterotrophic bacteria, pseudomonads, coliforms/Enterobacteriaceae, staphylococci and micrococci. This is surprising as the kitchen sink drain area has been reported in several studies to display one of the highest levels of microbial contamination, including coliforms and faecal coliforms, when several different sites in domestic kitchens were compared (3,7,10,12).
(f) Total culturable staphylococci and micrococci based on sum of all colonies cultured on mannitol salt agar.
In our study, commensals such as diphtheroids, micrococci
, and bacteroides were noted in less number of migraine patients.
 In our study Micrococci
sp was isolated from acute dacryocystitis (3.77%) but not in cases of chronic dacryocystitis, however studies reporting Micrococci
as pathogen in acute dacryocystitis are limited, but repeated isolation confirms their pathogenicity.
To the Editor: Bacteria belonging to the former genus Micrococcus, the so-called micrococci, are usually regarded as contaminants from skin and mucous membranes.
The traditional identification of the micrococci is based on their susceptibility to lysozyme and bacitracin and their resistance to lysostaphin and nitrofurantoin, in contrast to staphylococci, which display the opposite pat tern.
Of the 19 units manifesting growth, 16 yielded only diphtheroids, 1 unit grew coagulase-negative staphylococci, 1 unit grew diphtheroids and micrococci
, and 1 unit grew diphtheroids and coagulase-negative staphylococci.
