Poult Enteritis and Mortality Syndrome in Turkey Poults: Causes, Diagnosis and Preventive Measures

Abstract

Poult enteritis and mortality syndrome (PEMS) is one of the most significant problem affecting turkeys and continues to cause severe economic losses worldwide. Although the specific causes of PEMS remains unknown, this syndrome might involve an interaction between several causative agents such as enteropathogenic viruses (coronaviruses, rotavirus, astroviruses and adenoviruses) and bacteria and protozoa. Non-infectious causes such as feed and management are also interconnected factors. However, it is difficult to determine the specific cause of enteric disorders under field conditions. Additionally, similarities of clinical signs and lesions hamper the accurate diagnosis. The purpose of the present review is to discuss in detail the main viral possible causative agents of PEMS and challenges in diagnosis and control.

Metagenomic Identification of Novel Eukaryotic Viruses with Small DNA Genomes in Pheasants

“…In pheasants, viral intestinal problems have been linked to rotaviruses and caliciviruses [4]. However, viral enteric diseases (e.g., poultry enteritis and mortality syndrome or PEMS) in other galliform birds have been shown to be multi-etiological health problems [5], suggesting that similar syndromes in game birds can be more complex than currently recognized. Metagenomic characterization of viruses from pheasants with intestinal disease is an obvious option to help elucidate the viral spectrum associated with gut infection in this avian species.…”

“…Dentre as enfermidades que induzem a perdas econômicas no setor de avicultura estão justamente as rotaviroses (DHAMA et al, 2015;DEOL et al, 2017;SHEHATA et al, 2021). A doença no contexto da avicultura industrial é causada pelos rotavírus dos sorogrupos A, D, F e G, que conforme dito anteriormente são os sorogrupos descritos nessa espécie (DHAMA et al, 2015;.…”

“…A doença no contexto da avicultura industrial é causada pelos rotavírus dos sorogrupos A, D, F e G, que conforme dito anteriormente são os sorogrupos descritos nessa espécie (DHAMA et al, 2015;. Assim como nos outros hospedeiros, a doença se manifesta através de sinais clínicos relacionados ao sistema gastrintestinal, como diarreia, alterações no apetite, no ganho de peso e no crescimento (DEOL et al, 2017;CADDY et al, 2020;SHEHATA et al, 2021). A principal via de transmissão do rotavírus aqui também é a fecal-oral (DHAMA et al, 2015), e em ambientes de produção, nos quais as aves permanecem confinadas essa transmissão pode se dar ainda mais facilmente.…”
