To avoid fatal acute hemolytic reactions in subsequent blood transfusions, it is important to recognize blood groups and to blood type both the donor and the recipient. Prevalence of dog blood groups varies geographically and between breeds. Our aim was to determine DEA 1 prevalence in a canine population in Luanda (Angola) and to assess alloimmunization risk after a mismatched blood transfusion. Blood samples were typed using an immunochromatographic strip technique. Of the 112 dogs tested (59 males; 53 females), 52.68% were DEA 1 positive and 47.32% DEA 1 negative. Females tended to be DEA 1 positive, and males DEA 1 negative (p = 0.0085). In a first-time mismatched blood transfusion, the calculated probability of a dog becoming sensitized was 24.9% and the probability of an acute hemolytic reaction following a second incompatible blood transfusion was 6.21%. DEA 1 prevalence obtained was similar to that reported worldwide, but differs from other African countries. The risk of alloimmunization and acute hemolytic transfusion reactions in mismatched blood transfusions is higher than that in other African regions. Blood typing is recommended prior to transfusion.<\/jats:p>","DOI":"10.3390\/vetsci11090449","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T08:54:17Z","timestamp":1727168057000},"page":"449","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Dog Blood Type DEA 1 in Two Municipalities of Luanda Province of Angola (Sub-Saharan Africa)"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7114-6918","authenticated-orcid":false,"given":"Ana C.","family":"Silvestre-Ferreira","sequence":"first","affiliation":[{"name":"Department of Veterinary Sciences, University of Tr\u00e1s-Os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Animal and Veterinary Research Centre (CECAV), University of Tr\u00e1s-Os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Science\u2014AL4AnimalS, 5000-801 Vila Real, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3976-1619","authenticated-orcid":false,"given":"Hugo","family":"Vilhena","sequence":"additional","affiliation":[{"name":"Animal and Veterinary Research Centre (CECAV), University of Tr\u00e1s-Os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Science\u2014AL4AnimalS, 5000-801 Vila Real, Portugal"},{"name":"Center for Investigation Vasco da Gama (CIVG), Department of Veterinary Sciences, Escola Universit\u00e1ria Vasco da Gama (EUVG), 3020-210 Coimbra, Portugal"},{"name":"Onevetgroup University Veterinary Hospital of Coimbra (HVUC), 3020-210 Coimbra, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana C.","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Casa dos Animais Veterinary Clinic, Luanda, Angola"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 R.","family":"Mendoza","sequence":"additional","affiliation":[{"name":"Casa dos Animais Veterinary Clinic, Luanda, Angola"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Garcia","family":"Aura","sequence":"additional","affiliation":[{"name":"Casa dos Animais Veterinary Clinic, Luanda, Angola"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josep","family":"Pastor","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, Universitat Aut\u00f2noma de Barcelona (UAB), Bellaterra, 08193 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1323","DOI":"10.1016\/S0195-5616(95)50157-3","article-title":"Canine blood groups and their importance in veterinary transfusion medicine","volume":"25","author":"Hale","year":"1995","journal-title":"Vet Clin.
