Many serological techniques have been developed to aid in the discrimination of significant candidiasis from other clinical states. Serum anti-candida precipitin and agglutinin quantification by counterimmunoelectrophoresis and latex agglutination were statistically evaluated as to their respective ability to accomplish this discrimination. Forty-five serum specimens from 16 patients with docum...

Razzak: [email protected]). 3Department of Microbiology, College of Veterinary Medicine, University of Duhok, Duhok, Iraq. ABSTRACT To identify the true contribution of toxoplasmosis to fetal loss and bad obstetric history, we tested 310 women, 77.4...

Five gentamicin assay procedures (a bioassay, an enzyme immunoassay, a latex agglutination inhibition test, a fluorescence immunoassay, and a radioimmunoassay) were evaluated to determine which was optimal for our laboratory. The evaluation was based on recovery and precision studies and results of analyses of patient samples, as well as technical assay performance factors. The latex agglutinat...

The penicillin binding protein 2a (PBP2a) latex agglutination test using a blood culture pellet was compared to the oxacillin screen agar method using isolated colonies. For blood cultures positive for Staphylococcus aureus (n = 70), the direct PBP2a test was 18% sensitive and 100% specific. The PBP2a test shows poor sensitivity when used directly with positive blood cultures.

Sputum specimens from 480 patients were examined for the presence of pneumococci by Gram film and culture and for pneumococcal antigen by counterimmunoelectrophoresis, coagglutination, and latex agglutination. Ninety six positive specimens were detected. Gram film and culture provided the most reliable techniques in well taken specimens collected early in the illness before antibiotic treatment...

BACKGROUND Cryptococcus neoformans is frequently present as an opportunistic pathogen mainly affecting immunocompromised populations. Disseminated C. neoformans infection in immunocompetent population is rare and usually involves lung and central nerve system. Cryptococcus from biologic samples can easily grow on routine fungal and bacterial culture media. Besides, cryptococcal latex agglutinat...

Fatal toxoplasmosis was diagnosed in a Blanford's fox (Vulpes cana) from the United Arab Emirates. Toxoplasma gondii-like tachyzoites were found associated with necrosis in intestine, spleen, liver, kidneys, lungs, skeletal muscle, brain and heart. Protozoal tachyzoites reacted positively with T. gondii-specific polyclonal antibodies. Antibodies to T. gondii were detected in 10 of 12 V. cana as...
