Remarks of Eimeria labbeana infection in Egyptian pigeons

Abstract

This work was conducted to investigate the course of Eimeria labbeana infection in Egyptian pigeons (Columbia Livia). Thirty squabs were experimentally infected orally with 2.5 x104 sporulated Eimeria labbeana oocysts. Daily scarification of three squabs was done from day one post-infection (PI) until day 8 PI for following of the endogenous stages in tissue samples and 6 squabs were kept to follow the patent period and daily oocyst shedding. Paraffin-embedded intestinal samples were sectioned and stained for differentiation of parasitic stages. The infected squabs showed greenish watery diarrhea, weakness, rough feathers, and decrease food intake at day 5 PI. The pre-patent and patent periods were 6 and 14 days PI respectively. The oocyst shedding started at day 6 PI and reached the peak at day 8 PI. Histopathological examination revealed the presence of three schizont stages, macro-and micro-gametes, and oocysts in the duodenal and jejunal parts of the small intestine. In conclusion, it is the first study on Egypt on Eimeria labbeana in Egyptian pigeons and its biology is like recorded before.

Incidence of gastrointestinal parasites in pigeons with an assessment of the nematocidal activity of chitosan nanoparticles against Ascaridia columbae

“…Avian coccidiosis is adevastinting problem facing avian spp. ( Abolhadid et al, 2021 ; El-Shall et al, 2022 ; Salem et al, 2022b ). With this study, the all-over prevalence of E. columbae in pigeons was (79%) and the coccidia highest incidence was recorded in adults (95%) then squabs (47.5%).…”

Prevalence of Intestinal Parasites Infesting Domestic Pigeons with Histopathological Changes at Taif Governorate, KSA

“…Protozoal infestation is a big problem that faces avian spp. [45][46][47]. In this study, we have recorded mixed infections between different gut parasites with a prevalence rate of 10.8% (23/212).…”
