Infecção pelo vírus influenza A em suínos no sul de Moçambique

Abstract: RESUMO: A influenza suína (IS) é uma doença aguda e altamente contagiosa do trato respiratório de suínos, causada pelo vírus influenza A (VIA). A doença provoca perdas econômicas na suinocultura e também, tem importância na saúde pública devido ao seu potencial zoonótico. O objetivo deste trabalho foi relatar a infecção pelo VIA em suínos de Moçambique e realizar a caracterização anatomopatológica e imuno-histoquímica (IHQ) das lesões pulmonares associadas. Pulmões de 457 suínos abatidos foram avaliados e cole… Show more

“…The high concordance of 67.3% (101/150) between qPCR positivity and histologic lesions suggestive of M. hyopneumoniae was expected, once BALT hyperplasia is a characteristic finding of fully developed mycoplasma pneumonia (Blanchard et al 1992, Caswell & Williams 2016. However, in 16% (24/150) of the samples there was a disagreement between the presence of BALT hyperplasia and the lack of M. hyopneumoniae qPCR detection which could be due to the fact that BALT hyperplasia is not a pathognomonic histopathologic lesion for M. hyopneumoniae, and can be seen in cases of pneumonic lesions caused by other agents as IAV (Laisse et al 2018). In addition, a total of 12% (18/150) of the samples were M. hyopneumoniae positive by qPCR without presenting BALT hyperplasia.…”

“…Seus principais subtipos que infectam suínos são H1N1, H1N2 e H3N2. Contudo, os suínos também podem se infectar com outros subtipos do VIA, originários de humanos e aves, o que os torna um hospedeiro importante na epidemiologia da infecção pelo vírus (LAISSE et al, 2018).…”
