Abstract
Serologic tests are important for the detection of specific antibodies against infectious agents. Commercial indirect ELISA are costly and usually as effective as in-house ELISAs. In the present work, it was prepared a batch of Anaplasma marginale crude antigen from infected blood, and tested it against official positive and negative serum controls and compared with an old batch of antigen. The new antigen batch showed an efficiency similar to the old batch. The sensitivity of the test was comparable between the new and old batches. Both, new and old antigen lots are being used at an excess. The new antigen lot is large enough to run thousands of tests at a more affordable price than commercial kits.
期刊介绍：
The MEXICAN MAGAZINE OF SCIENCES PECUARIAS is an organ of scientific and technical diffusion of the livestock sector. Its periodicity is quarterly and arbitrated by pairs in the double-blind mode. Its objective is to make known the results of the research carried out by any scientific institution, in Mexico and in any part of the world, related to the livestock sciences, particularly those that refer to the different disciplines of Veterinary Medicine and Animal Science. The Journal is bilingual, publishes the complete articles in Spanish or English and is included in various indexing services and international dissemination platforms, such as the Index of Mexican Journals of Scientific and Technological Research of the National Council of Science and Technology (CONACYT); In the EBSCO Host database; In the Network of Scientific Journals of Latin America and the Caribbean, Spain and Portugal (RedALyC); In the Ibero-American Network of Scientific Journals of Free Access Veterinary Medicine. Indexed in the ISI Journal Citation Report Science Edition; And Elsevier''s SCOPUS and EMBASE indices.
