Seven- to eight-week-old rabbits were infected with Eimeria intestinalis Cheissin, 1948, a highly immunogenic coccidium, or Eimeria flavescens Marotel et Guilhon, 1941, which is weakly immunogenic. Immune response was investigated at 7, 14 and 21 days post inoculation (DPI). The level of serum immunoglobulins, lymphocyte proliferation stimulated by parasite antigens and weight of mesenteric lym...

It is known from studies in a wide range of wild and domestic animals, including elephants, that parasites can affect growth, reproduction and health. A total of 458 faecal samples from wild elephants were analysed using a combination of flotation and sedimentation methods. Coccidian oocysts (prevalence 51%), and nematode (77%) and trematode (24%) eggs were found. Species were not identified, t...

To determine the prevalence of helminth eggs in public places and children's playgrounds, 112 soil samples were collected in 26 sites in Shiraz, southern Islamic Republic of Iran, during September 2002-September 2003. Toxocara cati ova were found in 7 (6.3%) samples, 2 had Ascaris lumbricoides ova, 3 had larvae morphologically similar to Strongyloides stercoralis. Coccidia oocysts were also obs...

persons and the public health relevance of this emerging pathogen as a potential cause of diarrheal outbreaks (3,4) make prompt disclosure of the epidemiologic features and behavior of the parasite necessary. As we propose the possible participation of poultry in the epidemiologic cycle of the coccidia, we invite other Cyclospora working groups worldwide to confirm the so far putative reservoir...

The genus Cyclospora is in the subclass Coccidia, phylum Apicomplexa. This genus is taxonomically related to coccidian genera in humans. This organism has previously been referred to as a cyanobacterium-like body (CLB) and, in recent years, a new coccidian pathogen, Cyclospora cayetanensis, has been putatively identified (1, 2). No other species of Cyclospora affecting humans have yet been dete...

Antibiotic DE-3936 was isolated from the fermentation broth of a streptomycete No. 9735-1, which is identified as a strain of Streptomyces hygroscopicus. The antibiotic is a hydrophobic compound having the molecular formula of of C44H75O14Na and is active against Gram-positive bacteria, mycobacteria, mycoplasma and protozoa, especially coccidia. Its chemical and biological properties indicate ...

Experiments were conducted on male, Sprague-Dawley rats of the same age fed a standard laboratory diet to determine the comparative effects of single and concurrent subclinical infections by coccidia (Eimeria nieschulzi) and roundworms (Nippostrongylus brasiliensis) on nutritional status and metabolism. All infections produced anorexia, but it was more prolonged and intense with the concurrent ...

Gastrointestinal parasites are among the major causes of severe losses to livestock industry worldwide, especially in small ruminants. This study was conducted to determine the prevalence of gastrointestinal parasites in goats kept by small holders in the urban and peri-urban areas of Mwanza City in Tanzania. Randomly, 36 farmers from urban areas, with a total of 280 goats and 22 farmers from p...

Between 1989 and 1998, 3,504 rodents of the genera Dipodomys and Perognathus were collected from 4 permanent collecting sites on the University of New Mexico's Long Term Ecological Research station, located on the Sevilleta National Wildlife Refuge (SNWR), Socorro County. New Mexico. All animals were killed and examined for endoparasites (acanthocephalans, cestodes, coccidia, and nematodes). Th...

Rabbit coccidiosis causes great economic losses to world rabbitries. Little work has been done considering genetic manipulation on the etiological agents, rabbit Eimeria spp. In this study, we constructed a transgenic line of Eimeria magna (EmagER) expressing enhanced yellow fluorescent protein (EYFP) and red fluorescent protein (RFP) using regulatory sequences of Eimeria tenella and Toxoplasma...
