A test depending on the production of ethanol by Escherichia coli from lactose and dimethyl disulfide by Proteus spp. from methionine in the early exponential phase of growth and the detection of these products by head-space gas-liquid chromatography has been applied to 75 specimens of urine selected to provide the most stringent trial of the test. The test was found to be rapid and reliable fo...

Polyclonal antisera raised against Plasmodium knowlesi reacted with NADP-specific glutamate dehydrogenase (GLDH) of P. knowlesi, GLDH of P. falciparum and GLDH of Proteus spp. The antisera did not react with NAD(P) GLDH from bovine liver. Polyclonal antisera raised against the GLDH of Proteus spp. cross-reacted with GLDH from P. falciparum. Monoclonal antibodies (McAbs) obtained from mice immun...

A simple, rapid, semiquantitative slide catalase test useful for differentiating members of the family Enterobacteriaceae is described. Judging by the time required for appearance of oxygen bubbles in 3% hydrogen peroxide, the immediate catalase reactors were Yersinia, Serratia, Proteus, Morganella, Providencia, Cedecea, and Hafnia spp. The delayed catalase reactors were Escherichia, Shigella, ...

To analyse the occurrence and prevalence of plasmid-mediated quinolone resistance (PMQR) genes in the tribe Proteeae, 81 isolates (65 Proteus spp., 12 Morganella morganii and 4 Providencia stuartii) consecutively collected in 66 hospitals belonging to the WHONET-Argentina Resistance Surveillance Network were studied. Of the 81 isolates, 50 (62%) were susceptible to quinolones [43/65 (66%) Prote...

The in vitro activity of R-3746, an iminomethoxy aminothiazolyl cephalosporin with a CH2OCH3 moiety at position 3, was compared with those of other antibiotics. R-3746 inhibited the majority of hemolytic streptococci (groups A, B, C, F, and G) and Streptococcus pneumoniae at less than 0.06 micrograms/ml, which was comparable to the activity of amoxicillin, 2- to 8-fold more active than cefixime...

This study was conducted to generate microorganisms isolated from cultures of ears taken from the patients diagnosed to have chronic otitis media and determine and compare the in vitro effects of different antibiotics on these microorganisms. Between June 2009 and October 2010, 127 ear cultures were taken from 100 patients who applied to the Department of Otolaryngology of Ataturk University Fa...

OBJECTIVE To study the in-vitro antimicrobial activity of Cefpirome: A new fourth generation Cephalosporin in comparison with other agents against clinically significant Gram-negative and Gram-positive bacteria. SETTING A multi-center in-vitro study was conducted in 13 centers. MATERIALS AND METHODS Bacterial isolates--A total of 1300 isolates were collected from different clinical laborato...

OBJECTIVE We undertook a microbiological study of purulent specimens from women with symptomatic breast abscesses. METHODS Fifty-one purulent samples were collected in 2 periods (December 1991-April 1992 and January 1994-June 1994) from nonpuerperal breast abscesses in 44 patients attending our hospital. RESULTS One of the most frequently isolated microorganisms was Proteus mirabilis (9 pat...

CSOM is mostly caused by bacteria, but fungi and virus can also be a cause of CSOM. The aerobic microorganisms most frequently isolated in CSOM are Pseudomonas aeruginosa, Staphylococcus aureus, Gram-negative organisms such as Proteus spp., Klebsiella spp., and Escherichia spp., Citrobacter species, Haemophilus influenzae, and Moraxella catarrhalis (Gül et al., 2006; Verhoeff et al., 2006; de M...
