We report a case of exclusive involvement of lymph node in leishmaniasis presenting as generalized lymphadenopathy. The diagnosis of lymphatic leishmaniasis was confirmed by the presence of Leishmania donovani body in fine needle aspiration cytology, positive direct agglutination test and anti-rK39 antibodies. The bone marrow aspiration was negative for Leishmania donovani body. This is the fir...

The penicillin binding protein 2a (PBP2a) latex agglutination test using a blood culture pellet was compared to the oxacillin screen agar method using isolated colonies. For blood cultures positive for Staphylococcus aureus (n = 70), the direct PBP2a test was 18% sensitive and 100% specific. The PBP2a test shows poor sensitivity when used directly with positive blood cultures.

Leptospirosis is one of the zoonotic diseases caused by different serovars of the species Leptospira interrogans.  The source of infection in humans is usually either direct or indirect contact with the urine of infected animals.  In this study, 400 human blood samples collected from tribal areas of Farsan and Koohrang cities in West Centeral Iran.  The serum samples were analyzed employing Mic...

background: dogs have been previously reported to be reservoirs of leishmania infantum as the etiological agent of human visceral leishmaniasis in iran. we report a case of canine visceral leishmaniasis (vl) caused by l. tropica from the north- west of iran where human visceral leishmaniasis is endemic. methods: the canine vl was initially screened by dipstick rk39 and direct agglutination test...

a 5-month old puppy with muco-cutaneous lesions in the chin, around lips and eyes was exam­ined physically and microscopically for leishmaniasis. muco-cutaneous lesions containing a large num­ber of amastigotes of leishmania spp. were observed . amastigotes were also detected in liver and spleen of the puppy. the animal was positive with dipstick rk39 kit and high level of anti- leishmania anti...

The ability of a rapid, latex agglutination test to diagnose rubella infection and to measure immune status was evaluated by comparison with the hemagglutination-inhibition (HAI) test, enzyme-linked immunosorbent assay (ELISA), and the neutralization (NT) test. The latex agglutination test accurately detected serological conversions in 74 pairs of sera representing 21 natural infections and 53 ...

Aims-To investigate the pathology in patients presenting with sudden onset neurological illnesses associated with Mycoplasma pneumoniae infection.Methods-M pneumoniae infection was diagnosed by a highly rigorous interpretation of serological markers initially using complement fixation, agglutination and IgM antibodies. Confirmation of the serological diagnosis was achieved using indirect immuno...

The prevalence of antibodies against Leishmania donovani in selected domestic and wild animal species in 2 villages in Sudan with active L. donovani transmission in humans was investigated. Screening of domestic animals (donkeys, cows, sheep, goats, camels and dogs) with the direct agglutination test (DAT) detected reaction rates above the cut-off titres in donkeys (68.7%), cows (21.4%) and goa...
