A Direct Agglutination Test for Leishmaniasis
The American Journal of Tropical Medicine and Hygiene, 1975Antigen suspensions of enzyme-treated, formalin-fixed promastigotes of three species of Leishmania (L. donovani, L. tropica, and L. braziliensis) were evaluated by using the direct agglutination test with serum samples from healthy individuals and patients with confirmed cases of visceral and cutaneous leishmaniasis.

Validation of a direct agglutination test prototype kit for the diagnosis of visceral leishmaniasis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 2013A freeze-dried antigen was developed with Leishmania (L.) infantum and used for the production of a prototype direct agglutination test kit for the laboratory diagnosis of visceral leishmaniasis (VL), called DAT-LPC. On this study the diagnosis validity of this prototype was performed.To evaluate the sensitivity and specificity 103 samples from ...

Laboratory diagnosis of visceral leishmaniasis (VL) is usually based on the detection of Leishmania amastigotes in samples of bone marrow or splenic aspirate obtained by invasive procedures. Serological tests serve as a useful adjunct and are especially valuable in early or highly immune cases where amastigotes may be too scanty to be seen easily.

Direct agglutination test for serologic diagnosis of Neospora caninum infection
Parasitology Research, 1997A direct agglutination test was evaluated for the detection and quantitation of IgG antibodies to Neospora caninum in both experimental and natural infections in various animal species. As compared with results obtained by the indirect fluorescent antibody test, the direct agglutination test appeared reliable for the serologic diagnosis of neosporosis ...

Operational validation of the direct agglutination test for diagnosis of visceral leishmaniasis.
The American journal of tropical medicine and hygiene, 1999The validity of the direct agglutination test (DAT) for visceral leishmaniasis (VL) was studied with a standardized field kit on 148 clinically suspected persons and 176 healthy controls recruited between 1993 and 1994 from an endemic area in Gedaref State, Sudan.

In this study, the direct agglutination test (DAT), using 2-mercaptoethanol (2-ME), kaolin or N-acetylcysteine (NAC) as sample diluents, was used to assay 89 samples from visceral leishmaniasis (VL) patients and 130 samples from patients with other diseases and healthy individuals. Maintaining a cut-off of 1:100, the DAT assays with 2-ME, kaolin or NAC

Parasitology Research, 2022
This study aimed to characterize agglutinating antibodies detected by the direct agglutination test (DAT-LPC) for the diagnosis of visceral leishmaniasis (VL). The DAT-LPC antigen/antibodies complex was recovered, washed, and used as antigenic substrate in a modified enzyme-linked immunosorbent assay (modified ELISA), revealed with anti-human IgM, IgG,

Direct agglutination test for Encephalitozoon cuniculi
Veterinary Parasitology, 2006Encephalitozoon cuniculi is a small protozoan parasite in the phylum Microspora. It has been shown to naturally infect several host species, including humans. Infection with microsporidia is usually asymptomatic, except in young or immunocompromised hosts.
