The group A rotavirus staphylococcal co-agglutination test was evaluated and its sensitivity and specificity compared with an in-house enzyme-linked immunosorbent assay (ELISA) and a commercial latex agglutination test (Rotalex). In addition, the storage stability of the staphylococcal reagents was ascertained. Examination of 136 clarified suspensions of diarrhoeal faeces by the staphylococcal ...

A total of 163 stool specimens were tested for detection of Clostridium difficile and its toxin by cytotoxicity assay with tissue culture, latex agglutination test, and isolation of the organism. From 33 specimens which were positive for toxin by cytotoxicity, 30 were positive by the latex agglutination test; the organism was isolated from 21. The total number of samples which were positive wit...

different examination have shown that rheumatoid factor is not responsible for false positive reaction (f.p.r.) in cr. neoformanse’s free capsular antigen latex agglutination test, whereas high levels of iron in sera of patients with rheumatoid arthritis as well as other sera was responsible not only for this f.p.r. , but also had an important role in the production of f.p.r. in many slide late...

b ackground: mediterranean type of visceral leishmaniasis (vl) is present in different parts of iran. several studies have identified dogs as the main reservoirs of the vl caused by leishmania infantum in iran and other mediterranean regions. this study aimed to determine the seroprevalence of canine visceral leishmaniasis as animal reservoir host for human visceral leishmaniasis in boyer ahmad...

background : visceral leishmaniasis (kala-azar) is an endemic disease in some areas of iran. a cross- sectional study was conducted for sero-epidemiological survey of visceral leishmaniasis (vl) in baft district from kerman province, southeast of iran. methods: blood samples  were  collected  from children  up to 12 years old and 10% of adult population from baft villages with a multi-stage ran...

rheumatoid factors (rf) are autoantibodies with specificity for the fc portion of human igg. production of rf is a characteristic feature of rheumatoid arthritis (ra) and is detectable in high titer in about 90% of these patients. in this study, we measured total igm, iga, igmrf and igarf in serum and synovial fluid of 45 ra patients by elisa and the results were compared with those obtained by...

background and objectives : 300 pseudomonas aeruginosa strains were isolated from hospitalized patients in iran. using international antigenic typing system (iats) antibodies, all strains were classified into 16 serotypes while serotype 14 was not identified among the 17 known serotypes. to evaluate the rate of cross-reactivity between o- antigenic determinants, monospecific polyclonal antibodi...

Cryptococcal antigen titers of 70 cerebrospinal fluid and 57 serum specimens from patients suspected of having cryptococcosis were determined both before and after treatment with pronase. Median titers of cerebrospinal fluid specimens before and after treatment were 128 and 128, respectively; mean geometric titers of these specimens before and after treatment were 102 and 204, respectively. Med...

background: visceral leishmaniasis (vl) or kala-azar is a parasitic disease caused by the species of leishmania donovani complex. mediterranean type of the disease is endemic in some parts of iran and more than 95% of cases were reported in children up to 12 years of age. this study was performed to determine the seroprevalence of vl in the rural areas of dashti district from bushehr province. ...

background: this study aimed to determine the seroprevalence of canine visceral leishmaniasis in meshkin-shahr district as endemic areas of human visceral leishmaniasis (hvl) for presenting control program of hvl to health authorities.  methods: a seroepidemiological study to determine seroprevalence of canine visceral leishmaniasis (cvl) among owner­ship dogs using direct agglutination tests (...
