Resumo: | Ochratoxin A (OTA) is a mycotoxin produced by species of Penicillium and Aspergillus, agricultural product contaminants. Chronic and sub-chronic OTA intoxication by chickens ingesting contaminated feed, leads to health damages due to its hepatotoxic, nephrotoxic, cytotoxic, immunotoxic, gastrotoxic, and possibly carcinogenic effects. As there are few data on acute intoxication, the present study evaluated the effects of a single acute OTA intoxication dose on immunological and hematological parameters in chicks. Sixteen one-day-old chicks were used, separated into two groups (n=8). A single dose of OTA (1400 µg kg-1 body weight) was administered, via gavage, for the OTA group and one dose of sterile PBS for the control group. On the 13th day, blood samples were collected to assess hematological and biochemical parameters, and on the 14th day, euthanasia and collection of lymphoid organs were performed. The animals of the OTA group demonstrated a significant decrease in total circulating leukocytes (p<0.001) with heteropenia (p<0.001) and lymphopenia (p=0.023), decrease hematocrit (p=0.020), hemoglobin (p=0.032), and plasma IgA (p =0.044), and increased plasma uric acid level (p=0.045), in relation to the control group. In addition, the animals intoxicated with OTA showed depletion of lymphoid cells in the bursa of Fabricius (p=0.016), but not in the thymus or spleen (p>0.05), compared to the control. For the other parameters: total plasma proteins, plasma IgY levels, and anti-Newcastle Disease Virus (NDV) vaccine titers from matrices, there were no significant differences between the analyzed groups (p>0.05), although there was a worsening tendency in contaminated animals. In conclusion, even a single acute OTA intoxication at a high dose, leads to the suppression of the systemic immune response, also affecting some hematological or biochemical parameters in chicks. |

Intoxicação crônica e subcrônica por OTA em frangos que ingerem ração contaminada, levam à danos à saúde devido aos seus efeitos hepatotóxicos, nefrotóxicos, citotóxicos, imunotóxicos, gastrotóxicos e possivelmente carcinogênicos. Como há poucos dados sobre intoxicação aguda, o presente estudo avaliou os efeitos de uma dose única de intoxicação aguda por OTA sobre parâmetros imunológicos e hematológicos em pintainhos. Foram utilizados 16 pintainhoss de um dia de idade, separados em dois grupos (n=8). Uma dose única de OTA (1400 µg kg-1 de peso corporal) foi administrada, via gavagem, para o grupo OTA e uma dose de PBS estéril para o grupo controle. No 13º dia foram coletadas amostras de sangue para avaliação dos parâmetros hematológicos e bioquímicos, e no 14º dia foi realizada a eutanásia e coleta de órgãos linfoides. Os animais do grupo OTA demonstraram diminuição significativa do total de leucócitos circulantes (p<0,001) com heteropenia (p<0,001) e linfopenia (p=0,023), diminuição do hematócrito (p=0,020), hemoglobina (p=0,032) e IgA plasmática (p=0,044) e aumento do nível plasmático de ácido úrico (p=0,045), em relação ao grupo controle. Além disso, os animais intoxicados com OTA apresentaram depleção de células linfóides na bolsa de Fabricius (p=0,016), mas não no timo ou baço (p>0,05), em relação ao controle. Para os demais parâmetros: proteínas totais do plasma, níveis plasmáticos de IgY e títulos de vacinas contra o Vírus da Doença de Newcastle (NDV) das matrizes, não houve diferenças significativas entre os grupos analisados (p>0,05), embora tenha havido uma tendência de piora nos animais contaminados. Em conclusão, mesmo uma intoxicação única aguda por OTA em alta dose, leva à supressão da resposta imune sistêmica, afetando também alguns parâmetros hematológicos ou bioquímicos em pintainhos.UEL2022-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4569410.5433/1679-0359.2022v43n6p2453Semina: Ciências Agrárias; Vol. 43 No. 6 (2022); 2453-2448Semina: Ciências Agrárias; v. 43 n. 6 (2022); 2453-24481679-03591676-546Xreponame:Semina.
