Streptococcal pharyngitis--rapid diagnosis by Gram stain.
Group A beta-haemolytic streptococci were isolated from 51 (9.8%) of 519 patients with pharyngitis. Throat culture results showed the mean sensitivity, specificity and predictive value of a positive Gram-stained smear of pharyngeal secretions as 70%, 89% and 69%. The data suggest that Gram staining of a smear directly from the swab is as accurate as and more speedy than a culture from the phary...

متن کاملCoagglutination test for rapid noncultural diagnosis of human Campylobacteriosis.
Forty diarrhoeic stool samples of domestic animal handlers in a rural area of India were cultured and screened for detection of Campylobacter jejuni by Co-agglutination technique (CoA). Seven C. jejuni strains were isolated by culture and 6 faecal samples gave positive CoA test. The specificity and sensitivity for negative and positive culture were 96.9% and 85.7% respectively. This is first re...
متن کامل[Diagnosis and treatment of streptococcal pharyngitis].
Common signs and symptoms of streptococcal pharyngitis include sore throat, temperature greater than 100.4 degrees F (38 degrees C), tonsillar exudates, and cervical adenopathy. Cough, coryza, and diarrhea are more common with viral pharyngitis. Available diagnostic tests include throat culture and rapid antigen detection testing. Throat culture is considered the diagnostic standard, although t...
متن کاملSerogrouping single colonies of beta-hemolytic streptococci from primary throat culture plates with nitrous acid extraction and Phadebact streptococcal reagents.
The serogrouping of isolated beta-hemolytic streptococcal colonies from throat cultures by a micronitrous acid extraction method employing Phadebact Streptotoccus Test reagents was compared with results obtained with the direct-plate Phadebact procedure and the autoclave and Streptomyces albus enzyme-lysozyme extraction methods. These data were compared with those from the Lancefield grouping o...
