Abstract: RESUMO.-[Metapneumovirus aviário subtipos A e B brasileiros: infecção experimental em frangos de corte e eϐicácia vacinal.] O Metapneumovírus aviário (aMPV) é um patógeno respiratório associado à síndrome da cabeça inchada (SHS) em galinhas. Apesar de vacinas vivas contra o aMPV serem utilizadas no Brasil, os subtipos A e B (aMPV/A e aMPV/B) são ainda encontrados no país, com (aMPV) is a respiratory pathogen associated with the swollen head syndrome (SHS) in chickens. In Brazil, live aMPV vaccines are current… Show more

“…Furthermore, to enhance the likelihood of detecting aMPV, farms were narrowed down to those with respiratory problems. Due to the relatively short viral shedding time [25,26], respiratory swabs or respiratory organs were collected from chickens showing mild to severe clinical signs from each farm. For blood collection, chickens less than three weeks old were excluded owing to the potential for maternal-derived aMPV-specific antibodies [27].…”

“…The detection rates of aMPV in northern Vietnam (17.2%) demonstrated a similar low prevalence to other countries. Three main possibilities for the low aMPV detection rates were: (i) aMPV poorly replicated in the respiratory tract of chickens compared to turkeys [45,46], (ii) relatively short viral shedding time (within one week post-infection) [25,26], and (iii) low level of viral shedding (the highest was about 10 2.7 TCID 50 /mL) [25]. Additionally, the sensitivity of the RT-PCR assay was known to affect the virus-detection results.…”

“…aMPV-C (consisting of North American and Eurasian lineages) was endemic in turkeys in the North Central USA before a successful eradication program, but it is likely endemic in some wild avian species; aMPV-C has recently been reported in wild mallards in the Netherlands and Italy [ 35 , 36 ]. Sporadic detections of aMPV-C in some avian species of minor economic importance (e.g., Muscovy duck and pheasant) in South Korea, China, and France, and aMPV-D in farmed turkey flocks in France, have also been reported [ 2 , 21 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. In South America, aMPV-A and B viruses are predominantly detected in commercial chicken flocks and wild birds in Brazil.…”
