The Freeze Preservation of Coccidia
Research in Veterinary Science, 1968Summary In quantitative studies on the recovery of coccidia after freezing to — 196°C., glycerol protected sporozoites of E. acervulina, E. tenella and E. maxima. Glycerol and dimethyl sulphoxide both protected sporocysts, but longer equilibration times were required.

Veterinary Parasitology, 1991
Faecal samples from goats were collected per rectum from February 1989 to January 1990. The numbers of oocysts per gram (OPG) of faeces were determined by the McMaster technique and identification of oocysts was made on sporulation. Infection was seen throughout the year, infecting on average 89.9% of 1092 adults and 94.0% of 151 kids. OPG of less than

Publisher Summary This chapter discusses the biology of fish coccidia. The oocyst and, particularly, the structure of its contained sporocysts, are important features in differentiating the genera and species of coccidia in fishes. Except for three genera, Cryptosporidium, Octosporella, and Isospora, the fish coccidia have oocysts containing four ...

Coccidia in sheep in South Australia
Veterinary Parasitology, 1987Faecal samples from 136 sheep from four different locations in South Australia were examined to determine the types and numbers of Eimeria spp. present. Coccidian oocysts were detected in 80% of the sheep and 11 different species of Eimeria were identified. The species detected (and their prevalence) were E. crandallis/E. weybridgensis (76%), E. ovina (

Studies on Drug Resistance in Coccidia
The Journal of Parasitology, 1955The addition of chemicals to poultry feed for preventing and controlling coccidiosis outbreaks has been widely and intensively applied in the United States during the past 6 years. This development has permitted the poultry-industry to expand greatly and has resulted in more efficient and economical production of poultry.

COCCIDIA OF ALEUTIAN CANADA GEESE
Journal of Wildlife Diseases, 1981Fecal samples from 122 captive and 130 free-ranging Aleutian Canada geese (Branta canadensis leucopareia) were examined for oocysts of coccidia. Free-ranging geese sampled on the spring staging ground near Crescent City, California were infected with Eimeria hermani, E. truncata, E. magnalabia, E. fulva, E. clarkei and Tyzzeria parvula.

Coccidia and Coccidiosis in the Domestic Fowl
1968Publisher Summary A new species of Eimeria has been described and the life cycles and pathogenicity of others have been re-examined. Species of Eimeria have been cultivated in the allantoic membranes of the developing chick embryo and some progress has been made in the cultivation of Eimeriu species in tissue cultures. More work ha5 been published on

Research on avian coccidia: An update
British Veterinary Journal, 1992Despite the availability of many anticoccidial drugs, infections caused by species of Eimeria continue to be a source of significant economic loss to the poultry industry. After two decades in which the use world wide of ionophorous antibiotics gave unparalleled control of coccidiosis, drug resistance is once again tipping the balance in favour of the ...
