First record of Aedes aegypti (L.) (Diptera: Culicidae) infected by the parasite Ascogregarina culicis (Ross) (Apicomplexa: Lecudinidae) in Argentina [PDF]

, 2005
n a survey for parasites and pathogens of Aedes aegypti conducted in La Plata, Argentina, an aseptate gregarine was found parasitizing larvae, pupae and adults of this mosquito species. This gregarine species was identified as Ascogregarina culicis based

A technique for separating oocysts from faeces [PDF]

Avian Pathology, 1975
A technique to separate oocysts from large amounts of faeces by a "Continuous-Flow-Different-Density-Flotation" method is presented. Measures to save labour and to decrease the risk of contaminating the laboratory as well as the oocyst isolate during the centrifugation and harvesting of the oocysts from the centrifuge are described.

Eimeria species occurrence varies between geographic regions and poultry production systems and may influence parasite genetic diversity [PDF]

, 2017
Coccidiosis is one of the biggest challenges faced by the global poultry industry. Recent studies have highlighted the ubiquitous distribution of all Eimeria species which can cause this disease in chickens, but intriguingly revealed a regional divide in

Eimeria oocysts in auxiliary feed trays represent a potential source of infection to young broiler chicks

Journal of Applied Poultry Research
Summary: Outbreaks of avian coccidiosis arise after newly-placed chicks ingest high numbers of Eimeria oocysts present in litter. Preventing coccidiosis depends on reducing the number of Eimeria oocysts ingested to a level that either induces or boosts ...

On Eimeria bragancaensis n. sp. (Apicomplexa: Eimeriidae) and tissue-cysts of an unidentified protozoan in the bat Peropteryx macrotis (Chiroptera: Emballonuridae) from Amazonian Brazil

Parasite, 2000
A description is given of the mature oocysts and endogenous stages of Eimeria bragancaensis n. sp., from the small intestine of the bat Peropteryx macrotis from north Brazil. Oocysts are spherical to sub-spherical, 15.9 x 14.6 μm (range 14-17 x 14-17.7).
