Detection of pneumococci in blood cultures by latex agglutination

Detection of pneumococci in blood cultures by latex agglutination.

Latex agglutination by use of the Pneumoslide test on clinical blood cultures detected 22 Streptococcus pneumoniae strains as the etiological agents in 47 streptococcal septic episodes. The other 25 isolates were identified as viridans streptococci or streptococci of groups A, B, D, or G. The test demonstrated 100% sensitivity, 92% specificity, and predictive values for positive and negative re...

agglutination . Detection of rotavirus by latex

I was very interested to read the letter of Dr Waitkins et al on the importance of Streptococcus milleri. We too isolate the organism from cases of empyema from time to time and would agree about the importance of S milleri in this context. Although we welcome this reminder about the pathogenicity of the organism, there is one aspect of the letter that could be misleading: S milleri apparently ...

Simple, rapid latex agglutination test for serotyping of pneumococci (Pneumotest-Latex).

The "gold standard" for epidemiological typing of Streptococcus pneumoniae (pneumococcus) is the capsular reaction test (Neufeld test) with antisera against the 90 pneumococcal polysaccharide capsules, i.e., serotyping. The method is labor intensive and requires a certain level of experience to be performed satisfactory, and thus it has been restricted for use in specialized reference or resear...

Detection of Clostridium difficile enterotoxin in neonates by latex agglutination.

Clostridium difficile enterotoxin (D-1) was detected in 13 symptomatic and nine asymptomatic neonates in the neonatal intensive care unit by latex agglutination test but was not found in 18 healthy neonates in two other newborn nurseries. Environmental contamination in the intensive care unit may have been the cause. An association between the presence of enterotoxin and clinical symptoms is di...
