Canine heartworm and heat treatment: An evaluation using a well based enzyme-linked immunosorbent assay (ELISA) and canine sera with confirmed heartworm infection status

Canine Heartworm Disease

Immunologic protection against canine heartworm infection.

This study was conducted to evaluate protective efficiency of three different protocols for vaccination in canine heartworm infection. To evaluate the three protocols of immunization, dogs were separately immunized with living larvae; 1) immunization with gamma-attenuated infective larvae, 2) with 50 micrograms/kg ivermectin-abbreviation, and 3) with chemical abbreviation plus Freund's complete...

Focus on Canine Heartworm Disease

The ingested microfilariae develop into the infective third-stage larvae (L3) after several molts. These L3 migrate to the mosquito head and mouthparts where they are deposited in hemolymph onto mammalian skin during subsequent blood meals. After the deposited L3 enter the host through the mosquito bite wound, they molt to fourth-stage larvae (L4). The L4 then migrate through the tissues toward...

Immunodiagnosis of Haemonchus contortus infection in sheep by indirect enzyme linked immunosorbent assay (ELISA)

Indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of H. contortus. Plate ELISA was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. Indirect plate ELISA was able to demonstrate...

DEVELOPMENT OF A SIMPLE AND SENSITIVE ENZYME- LINKED IMMUNOSORBENT ASSAY (ELISA) FOR CLINICAL MEASUREMENT OF TESTOSTERONE USING PENICILLINASE AS LABEL

An enzyme-linked immunosorbent assay using a homologous combination of antiserum raised against testosterone-3-0-carboxymethyloxime-bovine serum albumin (T-3-0-CMO-BSA ) and penicillinase-labelled T-3-0-CMO was developed. This assay was utilized to measure testosterone in serum samples of male and female subjects. The sensitivity of the assay is 50pg/well and the antibody developed crossrea...
