OBJECTIVE To evaluate the performance of serological tests using dried blood on filter-papers (micro-card agglutination test for trypanosomiasis (micro-CATT)) performed under field and laboratory conditions and using whole blood ((CATT/T.b. gambiense) (wb-CATT) and latex agglutination (LATEX/T.b. gambiense) (wb-LATEX)) for the serodiagnosis and surveillance of human African trypanosomiasis in W...
Evaluation of the oxoid dryspot streptococcal grouping kit for grouping beta-hemolytic streptococci.
The latex agglutination kits that are widely used for grouping of beta-hemolytic streptococci in clinical laboratories use liquid latex suspensions. The Oxoid Dryspot kit (Oxoid Ltd., Basingstoke, Hampshire, United Kingdom) uses predispensed latex dried onto reaction cards or cardboard strips. All streptococci of groups A (85 strains), B (87 strains), C (30 strains), D (38 strains), F (23 strai...
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...
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 ...
Titers in a direct agglutination test using Formalin-fixed toxoplasma tachyzoites were significantly higher in patients with acquired immunodeficiency syndrome with toxoplasmic encephalitis (TE) than in those without TE. In contrast, when fresh (not fixed) tachyzoites were used, the titers did not differ from those in patients without TE. The direct agglutination test using Formalin-fixed tachy...
The value of the latex agglutination test in meningitis was assessed. This was positive in 60% cases of Streptococcus pneumoniae, 93% of Haemophilus influenzae type b, and 39% of Neisseria meningitidis infections. We cannot support the view that this test was more valuable than Gram staining in partially treated meningitis and cannot recommend its routine use. It may, however, be valuable if Gr...
Methods Between January 1 2014 – July 15 2014, 5038 throat swabs were sampled from patients hospitalized in INBI Matei Balş according to standard methods. All beta-hemolytic streptococci suspected colonies were tested with bacitracin (0.04%) disks and we used the latex agglutination kit Omega Latex Diagnostic Avipath Strep. Erythromycin resistance testing was performed by disc 2μg Oxoid and cli...
A rapid slide test for the detection of degradation products of fibrinogen/fibrin (FDP) using a new antibody-coated latex particle is described. The latex particle has been specifically coated with antibody to fragments D and E. The latex agglutination test (Thrombo-Wellcotest) has been compared with the tanned red cell haemagglutination inhibition immunoassay (TRCHII) in 143 patients with a va...
Rheumatoid Arthritis (RA) is a systemic autoimmune disease. Production of Rheumatoid Factor(RF) is a characteristic feature of the majority RA patients. Previous studies showed there are differences between seropositive-RA(SP-RA) and seronegative-RA(SN-RA), regarding clinical manifestations. In this study the level of CRP was measured in serum and synovial fluid of 45 RA patients by latex a...
