Parasitic profiling of Japanese quails (Coturnix japonica) on two farms with conventional production system in the Amazon region

Abstract

The health monitoring and management systems of coturniculture can be deemed to be in a developmental phase when compared to the poultry industry. Studies regarding taxonomy and parasitic biology in quails (Coturnix japonica) has not been well conducted in Brazil. Most of the information is available from the autopsy case reports, in many ways the parasitic fauna of quails is still unknown. The aim of this study was to conduct a parasitological research in quails in order to contribute to ameliorate this situation. 31 quails, which were 12 months old, were used for the study. Their carcasses and viscera were sent to the Laboratory of Entomology and Tropical Diseases, INPA, Manaus/AM. The circulatory, nervous, respiratory, digestive and reproductive systems of these were studied separately. No blood parasites were found, however, nine species of endoparasites were registered which were distributed among the classes Cestoda, Nematoda and Protozoa. The helminths were distributed in the duodenum, jejunum, ileum, cecum and oviduct. The cecum was found to be the most parasitized organ and contained a wide range of parasites having three species of protozoa and three species of nematodes. Six morphotypes of Eutrichomastix globosus were recorded, and some morphotypes were hyperparasitized with sporangia Sphaerita sp. in the cytoplasm. A large number of parasites were recorded in this study, as well as the protozoan Blastocystis hominis was first being observed for quail.

Prevalência de endoparasitas em codornas japonesas (coturnix coturnix japonica) em dois aviários comerciais na região amazônica

“…Foram listadas várias infecções por Choanotaenia infundibulum em galinhas (Gallus Domesticus) nas diferentes regiões do estado de São Paulo, a primeira por Sawada (1970), a partir deste houveram mais relatos do cestódeo em outros grupos de aves (Monte et al 2018). A infecção por C. infundibulum é normalmente assintomática e moderadamente patogênica Research, Society and Development, v. 10, n. 9, e35010917967, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i9.17967 (Premaalatha et al 2014).…”

Há também um relato feito por Monte et al (2018), onde se observou a presença de Blastocystis homis em codornas.…”

“…Há quatro espécies de Eimeria que podem ser identificadas em codornas (Teixeira et al, 2004;Mohammad, 2012), baseadas na especificidade do local de desenvolvimento, entre elas: E. tsunodai, com desenvolvimento quase exclusivo no ceco (Tsutsumi, 1972), E. uzura (Tsunoda & Muraki, 1971) e E. bateri (Bhatia, Pandey & Pande, 1965) que habitam preferencialmente o duodeno e jejuno, respectivamente (Teixeira et al 2004, Gesek et al 2014. A presença de oocistos do gênero Eimeria foi visualizada, como no estudo relatado, em C. japonica em Manaus, Brasil (Monte et al 2018).…”

A Comprehensive Review on the Common Emerging Diseases in Quails.

“…Experimental challenge of young Bobwhite quail with Cryptosporidium and reovirus showed an increase in the oocyst shedding; indicating the synergistic action of parasites and viral infections (Guy et al, 1987). Monte et al (2018) demonstrated presence of different mixed protozoon parasites Eutrichomastix globosus, Sphaerita spp. and Blastocystis hominis in 12-week-old Japanese quails in Amazon region.…”

Ganho de peso de codornas europeias mantidas em ambiente controlado

“…No Brasil são duas as linhas de codorna criadas, sendo a coturnix coturnix japonica voltada exclusivamente para a produção de ovos e a coturnix coturnix coturnix, esta de origem europeia, voltada tanto para a produção de carne quanto de ovos, entretanto, a exploração de codornas tipo carne vem se constituindo em nova alternativa para o setor avícola (Corrêa et al, 2005;Oliveira, 2011;Monte et al 2018). São vários os centros de pesquisa públicos que se dedicam a trabalhos de melhoramento genético visando uma melhor eficiência produtiva das codornas (Murakami & Garcia, 2006).…”
