“…The measurements, in the beginning of the investigation, the measurements allowed to distinguish from closely related species. Initially, E. coturnicis (Chakravarty & Kar, 1947), E. tahamensis (Amoudi, 1987) and E. fluminensis (Teixeira & Lopes, 2002) were excluded. Despite the similar measurements, E. taldykurganica (Svambaev & Utebaeva, 1973) did not fit with the descriptions because it has a very different form, essentially ellipsoid with shape index 1.86.…”

“…Bhatia et al (1965), Tsunoda & Muraki (1971) and Tsutsumi (1972) described the three species characterized in this study, but did they lacked the current optical resources that allowed improved visualization and detailed descriptions of sporulated oocysts. Teixeira & Lopes (2002) and Teixeira et al (2004) described morphologic details of oocysts of these species, but some data essential for differentiation were not provided, such as flattening of one of the ends of the oocysts of E. tsunodai and the presence of SSB in all three species. Furthermore, in those articles the description of the SB as piriform in E. uzura and the SB as triangular in E. tsunodai was in fact making reference to the SB and SSB complex.…”

Eimeria spp. from Japanese quails (Coturnix japonica): new characteristic features and diagnostic tools

et al. 2013

RESUMO.-[Eimeria spp. de codornas japonesas (Coturnix japonica): novas características e ferramentas de diagnóstico.] A codorna japonesa Coturnix japonica originária do norte da África, Europa e Ásia, é utilizada mundialmente como um animal experimental e modelo para avicultura. O presente trabalho caracteriza Eimeria bateri, Eimeria tsunodai e Eimeria uzura recuperadas de C. japonica. Baseado no fato de que as codornas têm uma distribuição global, como são os seus coccídios, os resultados deste estudo devem propiciar o diagnóstico destas Eimeria spp. em outras regiões e continentes. Eimeria bateri demonstrou a maior intensidade de infecção e eliminaram oocistos a partir do quarto dia após infecção, em contraste E. tsunodai e E. uzura eliminaram oocistos a partir do quinto dia após infecção. As três espécies foram morfometricamente semelhantes e polimórficas. No entanto, a aplicação da regressão linear, histogramas e ANOVA proveram meios para a identificação destas espécies. Finalmente, o algoritmo foi totalmente eficiente uma vez que valores resultantes não foram sobrepostos. TERMOS DE INDEXAÇÃO: Coccidiose, diagnóstico, Eimeria bateri, Eimeria tsunodai, Eimeria uzura. INTRODUCTIONThe breeding of Japanese quails Coturnix japonica has excelled in aviculture, due to increased consumption of exotic meats and eggs, and represents an alternative to chicken production. In the USA, Japanese quails were introduced in the 1950s, and at that time the breeding of Japanese quails was already widespread in European countries. In Brazil, Japanese quails were introduced in the 1950s, but large scale production began in the mid 1960's (Howes 1964, Murakami & Ariki 1998, IUCN 2013, Jatoi et al. 2013.In addition to its importance for aviculture, the Japanese quail has become, in recent decades, an important experimental animal for scientific research. It is used extensively in studies examining genetics, nutrition, toxicology, em- The Japanese quail Coturnix japonica originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current paper characterizes Eimeria bateri, Eimeria tsunodai and Eimeria uzura recovered from C. japonica. Based on the fact that quails have a global distribution, as are their coccidia, the findings of this study should provide the means for diagnosis of those Eimeria spp. in other regions and continents. Eimeria bateri showed the greatest intensity of infection and shed oocysts from the fourth day after infection; in contrast, E. tsunodai and E. uzura shed oocysts from the fifth day after infection. The three species shared a high degree of similarity and were all polymorphic. Yet, the application of line regressions, histograms and ANOVA provided means for the identification of these species. Finally, the algorithm was very efficient since verified that resultant values were not superimposed.

“…Nowadays, quail coccidiosis and its planned control have become a major target in all countries (Duszynski and Gutierrez 1981;Mehlhorn 2006Mehlhorn , 2008. Several Eimeria species were described from the different species of quails in different countries such as Eimeria coturnicis from Coturnix coturnix coturnix, Eimeria uzura and Eimeria bateri from Coturnix coturnix japonica in India (Bhatia et al 1965;Rao and Sharma 1992), and E. uzura and Eimeria tsunodai from C. coturnix japonica in Japan (Tsunoda and Muraki 1971;Tsutsumi 1972;Teixeira and Lopes 2002;Teixeira et al 2004). Other Eimeria species had been described in North America (Fisher and Kelley 1977;Duszynski and Gutierrez 1981;Ruff 1985).…”

Light microscopic study on Eimeria species infecting Japanese quails reared in Saudi Arabian farms

Japanese quails Coturnix coturnix japonica reared in economic farms were individually investigated for coccidian infections. The results indicated the absence of infections in birds younger than 1 month. An Eimeria infection rate of up to 80% was detected in birds 7-9 weeks old with a general infection rate of 29%. The infection rate decreased to 21.42% in birds older than 10 weeks. Morphometric characteristics of freshly shed, unsporulated oocysts were taken. These oocysts appeared pale yellow in color, were oval to subspherical in shape being limited by a bilayered oocyst wall of 1.2 microm. The unsporulated oocysts measured 17.73 +/- 12.92 x 12.79 +/- 1.69 microm (mean of 100) and possessed a polar granule, a micropyle and an oocyst residuum. The sporulation took 72 h and resulted in the formation of four elongated sporocysts containing two sporozoites, in addition to a stieda body and a sporocyst residuum. The life cycle of this Eimeria species was followed in experimentally infected quails. Three asexual generations (at 60, 78, and 96 h p.i.) were detected in the epithelium of the small intestine before the sexual cycle started at 84 h p.i. The prepatent period was 5 days, while the patent period covered 6-7 days. Besides this well-defined species, another Eimeria species occurred, the oocysts of which were excreted in low numbers and were characterized by the absence of a micropyle and an oocyst residuum. These oocysts measured 15.73 +/- 2.22 x 14.18 +/- 1.89 microm (mean of 100) and sporulated already within 60 h.
