background: until now, the comparison of the rk39 strip test (rkt) and direct ag-glutination test (dat) for detection of visceral leishmaniasis (vl) is exclusively based on either positive or negative qualification of the reaction outcome. objective: in this study, we compared the diagnostic performance of rkt and dat for vl both qualitatively and semi-quantitatively. methods: for comparison ba...

background: visceral leishmaniasis (vl) is an endemic disease in some parts of iran. many techniques have been used for diagnosis of vl, among which the urine based la-tex agglutination test (katex) is a promising one. objective: to compare three diag-nostic tests of vl including katex, elisa and direct agglutination test (dat) in vl patients and healthy controls in the south west of iran. meth...

The prevalence of Toxoplasma gondii in free-range chickens from Campos dos Goytacazes, Rio de Janeiro State, Brazil, was examined to evaluate environmental contamination by oocysts. Antibodies against T. gondii were assayed by the modified agglutination test

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...

b a ckground: a two year seroepidemiological study was designed to find out the seroprevalence and risk factors ofcanine visceral leishmaniasis (cvl) among stray and owned dogs in tehran and alborz provinces of iran. me t hods: blood samples of  602 dogs living in  11  counties of  tehran and  alborz  provinces were  taken by venipuncture in 2008–2010. after separation of blood sera, anti-leish...

The lectin slide agglutination test for Neisseria gonorrhoeae has been modified and improved. Results show that wheat germ agglutinin and soybean lectin agglutinate 100% (193 of 193 tested) of clinical isolates of N. gonorrhoeae. Lectin-reactive meningococci can be readily identified by the hydrolysis of gammaglutamyl-3-naphthylamide. Branhamella catarrhalis, Neisseria lactamica, Neisseria sicc...
