Serological testing for infection in animals and man: Current status and opportunities for advancements.

Serological tests are widely used for the detection of spp. infections in animals and humans. Despite some limitations, (such as low sensitivity in the early period after infection) ELISA and western blot testing have demonstrated good performance when excretory/secretory products from muscle larvae are used as antigens in agreement with the International Commission on Trichinellosis. Over recent decades, considerable progress has been made in the characterization of -derived molecules in the hope of improving diagnosis, mainly during the early days post infection. Despite these efforts, validated tests using characterized antigens for early diagnosis are still not available. However, combining currently available sero-diagnostic tools with clinical and epidemiological data provides valuable information on infections in humans and animals as shown in this review.
