Commercial flocks infected by Eimeria species parasites, including Eimeria maxima, have an increased risk of developing clinical or subclinical coccidiosis; an intestinal enteritis associated with increased mortality rates in poultry. Currently, infection control is largely based on chemotherapy or live vaccines; however, drug resistance is common and vaccines are relatively expensive. The deve...

An experiment was conducted on one day old, 120 broiler chicks to study the effect of madar (Calotropis procera) leaf powder and amprolium supplementation caecal histology during coccidiosis. Broiler were divided into five groups (I-V) each with two replicates 12 chicks. Group I II provided unsupplemented diet, III supplemented 0.125% amprolium, group IV V 0.2% 0.4% respectively. On 15th experi...

Hemorrhagic diarrhea in poultry is caused by Eimeria tenella, the most pathogenic avian coccidian parasite, and new approaches to treat the disease are continually being sought. Although eimeripain, a cathepsin B-like cysteine protease from E. tenella, has recently been identified as a novel anticoccidial drug target, its localization during the intracellular development of parasites remains un...

Two new species of Eimeria were observed in the feces of captive white-tailed deer fawns, Odocoileus virginianus, from Alabama. The first new species was easily recognized because of its small size. Sporulated oocysts are spherical, average 10.2 by 10.0 microm, and lack a micropyle and oocyst residuum. Oocysts contain a polar granule and elongate-ellipsoidal sporocysts that measure 6.7 by 3.1 m...

Fecal samples from 12 Pipistrellus kuhlii captured at Shagrah, Saudi Arabia, were examined for coccidia and three (25%) found to harbor a undescribed eimerian, herein described as Eimeria pipistrellus n. sp. Sporulated oocysts were subspherical, 24.8 x 23.2 (22-27 x 20-25) microns, with a bilayered and smooth wall. The micropyle was absent, but a large oocyst residuum and a single polar granule...

Feces from southern brown bandicoots, Isoodon obesulus, inhabiting the Perth metropolitan area were examined using fecal flotation and light microscopy, and were frequently found to contain oocysts (10/24; 42%). To enable formal description of the proposed new Eimeria species, i.e., Eimeria quenda n. sp., fecal oocysts from 1 juvenile male I. obesulus were allowed to sporulate in 2% potassium d...

Macrophage migration inhibitory factor (MIF) was the first cytokine to be identified almost 40 years ago. Homologues of MIF have been isolated recently from invertebrates, making it an interesting molecule from an evolutionary as well as functional perspective. The present study represents the first report of MIF homologues in apicomplexan parasites, belonging to the genus Eimeria. A single ful...

Avian coccidiosis is a huge problem worldwide. Heavily infected animals that show severe clinical signs and coccidiostat resistance are causing important economic losses. The present study aimed to update the recent cases of coccidiosis in Central Java, Indonesia, and to show the importance of the disease in the region. A total of 699 samples were obtained from different chicken breed. Differen...
