| Sumario: | 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%). |
