Avian strains of Escherichia coli (213) were subjected to in vitro antibiotic sensitivity tests with twenty-four different chemotherapeutic agents. Chlorhexidine, polymyxin B, colistin, and nitrofurazone exhibited the greatest inhibitory activities against these strains. Various potencies of antibiotics were compared. The activity of sulfachloropyridazine on various types of media failed to sho...

The classification of the genus Proteus is still to some extent controversial, although recent investigations have clarified the position considerably. The basis of the modern work was the demonstration by Moltke (1927) that 194 Proteus strains all rapidly hydrolysed urea. For the purposes of this paper, the genus Proteus includes all motile, Gramnegative, straight rods which do not ferment lac...

s: This study was conducted in a tertiary hospital at Bareilly, Uttar Pradesh between Aug 2009 and July 2010 to check the changing pattern of antibiotic sensitivity among uropathogens causing urinary tract infections (UTI). A total of 170 urine culture sensitivity reports were analyzed. The predominant growth of single bacteria was seen in 143 (84.12%) samples. The most common organisms isolate...
