“…The prepatent periods recorded for the three Eimeria spp. from experimentally infected quails in this study (4 days for E. bateri, and 5 days for E. tsunodai and E. uzura) were similar to those described by Bhatia et al (1965), Tsunoda & Muraki (1971) and Bashtar et al (2010). With regards to transmission, E. bateri appeared to be the most successful in mixed infections, based on the observation that it shed a greater quantity of oocysts during the experimental period (Fig.1).…”

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.

“…In such cases, the progression of coccidiosis may adopt a subclinical, chronic form (7). Three Eimeria species have been identified and described in Japanese quails (Coturnix coturnix japonica): Eimeria uzura, E. bateri, and E. tsunodai (2,7,8,10). Depending on Eimeria species, parasites damage the mucosa of different parts of alimentary tract due to replication through a series of asexual and sexual cycles.…”

The aim of this study was to investigate pathomorphological changes in the duodenum, jejunum, ileum, and caecum of Japanese quails naturally infected with Eimeria tsunodai. Samples of the intestines were collected from 6-week-old cockerels and hens before laying and from laying quails aged 12, 24, and 48 weeks. The tissue sections were stained with haematoxylin and eosin, PAS method according to McManus, and Ziehl-Neelsen method. Morphometric and morphological analyses of coccidia revealed that Eimeria tsunodai was responsible for the infection. Different developmental stages of the coccidia were observed almost exclusively in the caecum, and they led to the complete damage of caecal mucosa. The main changes observed in the caecum involved mucosal damage, atrophy of the folds and crypts, and mucosal desquamation. No significant inflammation changes were detected. The degree of damage to caecal mucosa increased with age and the greatest damage was noted at the age of 48 weeks. Eimeria tsunodai infections occur in Japanese quails during the entire laying period. Different developmental stages of coccidia are responsible for total damage to caecal mucosa.

“…Quail (Coturnix coturnix) is one of the smallest poultry birds provide more advantages than chickens such as its resistance to many poultry diseases, its greater capacity to benefit from food, high production proportions, and low feed intake. Additionally, they characterized by primary low costs which do not require wide area for farming, lucrativeness, and entertainment so it represented a modern poultry industry trend (Bashtar et al, 2010;Bahar et al, 2014).…”

The present study was conducted to investigate the prevalence and identification of most common parasitic infections of quails and to determine their seasonal variation. One hundred diseased quails (60 quails in summer and 40 quails in winter) were obtained from quail farms in different localities of Assiut and El-menia Governorates and were examined for the presence of ectoparasites, endoparasites, intestinal protozoa, blood protozoa and parasites of other organs (lungs, brain and liver). Results revealed that neither ectoparasites nor macroscopic parasites were observed in the examined quails. Mainly, the encountered parasites were intestinal protozoa (44%), blood protozoa (25%) and parasites of other organs (28%). The overall parasitic infection rate in the examined quails was higher in cold season (57%) than warm season (53%). The intestinal protozoa were identified including Eimeria spp. (30%), Cryptosporidium spp. (19%), Tetratrichomonas galinarum (15%), Cyclospora spp. (4%), Isospora spp. (3%) and Microsporidia spp. (3%). The prevalence rate of intestinal protozoal infection was higher in warm season 46.6% (28 out of 60 examined birds) than cold seasons 40% (16 out of 40 examined birds). The incidence rate of mixed intestinal protozoal infection was higher (24.8%) than the single infection (18.8%). The blood protozoa were reported including Leucocytozoon spp. (9%), Babesiosoma spp. (8%), Aegyptianella spp. (7%), Plasmodium gallinaceum (4%), Haemoproteus spp. (4%), Atoxoplasma spp. (1%) and Ehrlichia spp. (1%). The prevalence of parasitic infection in other organs showed that respiratory tract (trachea and lung) infection with Cryptosporidium spp. (24%), hepatic histomoniasis (3%) and brain toxoplasmosis (7%).
