is considered among the most pathogenic species in goats. The aim of this study was to isolate an strain and to assess its infectivity, pathogenicity, and ability to develop a protective immune response. After previous collection of -positive faeces, purification of oocysts, and amplification in donor animals, an experimental infection was carried out.

Background: Sheep coccidiosis could disturb the balance of intestinal microbiota, causing diarrhea, and even death in lambs. Chemical drugs are the primary method of treating sheep coccidiosis, but their use will bring drug resistance, toxic side effects, drug residues, and other problems. Chinese herbal medicines are investigated as alternative methods for controlling coccidian infections.

Swine coccidiosis is a host-specific protozoan disease caused by Cystoisospora suis and various Eimeria species, leading to diarrhea or subclinical signs in pigs. In this study, 3296 fecal samples from 55 farms across six provinces in China were collected and examined to determine the prevalence and molecular characteristics of swine coccidia. The single oocyst isolation technique (SOIT) and molecular characterization identified nine coccidian species, with an overall infection prevalence of 13.

Purpose: Flotation methods are widely used to detect oocysts/cysts of protozoans and eggs of helminths, except trematodes. However, details regarding the concentration and recovery rates of these parasites are poorly understood.
Methods: Using Eimeria tenella oocysts as a model parasite, the present study evaluated three check points: (1) the proportion of parasites that remain floating in flotation solution (sucrose or saturated saline) during centrifugation, (2) the proportion of oocysts that naturally float after addition of flotation solution after centrifugation, and (3) the rate of recovery on cover slips after completion of the flotation protocol.

This study assessed the prevalence and risk factors associated with gastrointestinal parasite infection in goats in Ayacucho, Peru. Fecal samples were collected from a total of 254 goats from four districts of Ayacucho: Ocaña (89), Colca (76), Pacaicasa (64), and Luricocha (25) during the dry season; recording the location, sex, and age of the animals. The fecal samples were analyzed using the flotation technique in salt and sugar solution, and modified McMaster egg counting techniques for eggs/oocysts (epg/opg) of gastrointestinal parasites.
