Toxoplasma gondii is a cosmopolitan protozoan parasite that has a wide range of intermediate hosts. It infects all warm-blooded animals, including humans and birds. The latter typically pick up the infection by ground feeding, and people can contract the parasite from eating undercooked chicken meat. In recent years, investigations into T. gondii infection in poultry have been reported worldwide.

Neospora caninum, Toxoplasma gondii and Brucella melitensis are pathogens that cause abortion in small ruminants. Besides, B. melitensis and T. gondii are zoonotic pathogens. The aim of this study was to describe the frequency of antibodies against N. caninum, T. gondii and B. melitensis in sheep and goats from three provinces of the center region of Argentina.

Toxoplasmosis is a worldwide zoonotic disease caused by infection with the intracellular protozoan parasite Toxoplasma gondii, posing significant economic losses to the livestock industry. As a major livestock province, little is known of the prevalence of T. gondii infection in sheep and cattle in Shanxi Province, North China.

To understand the transmission of Toxoplasma gondii, this parasite's genetic diversity distribution in free-living hosts is essential. This research's objective is the molecular genotyping of T. gondii isolates from the brain and muscles of Columbidae, Corvidae, Rattus, and Felidae of Mianeh County, East-Azerbaijan Province, Northwest Iran. Three hundred fifty samples were taken. For the genotyping of T.

Cryptosporidium parvum is a main cause of severe diarrhea in young calves leading to economic loss and animal suffering. Little is known about the epidemiology of the genetic subtypes that may differ in their infectiousness and zoonotic potential. The present study analyzes the distribution of Glycoprotein 60 (GP60) variants in C.

Consumption of undercooked meat is one of the main transmission routes for Toxoplasma gondii worldwide. In the South American Andes, the guinea pig (Cavia porcellus) is a domestic rodent representing one of the main sources of animal proteins for indigenous communities. Although T. gondii infects a wide range of rodents worldwide, the natural impact of the infection on guinea pig populations is still unknown.

Toxoplasmosis has been reported in Nigeria using several diagnostic tools with high prevalence in humans and some food animals. Rodents have been recognised as vital intermediate hosts of Toxoplasma gondii. However, there is paucity of information on the occurrence of T. gondii in wild rats found in Nigeria. This study aimed at molecular detection of T.

Cryptosporidium is a zoonotic protozoan parasite that is distributed globally and impacts both human and animal health. There are over 40 species of Cryptosporidium described to date, of which four (C. parvum, C. bovis, C. ryanae and C. andersoni) are routinely reported in cattle.

Giardia spp. is a protozoal parasite capable of causing diarrhea in mammals. Certain Giardia assemblages are potentially zoonotic. As part of a public health study, a questionnaire-based cross-sectional web survey was distributed among U.S. small and mixed animal veterinarians to assess perceived prevalence, preferred testing and treatment methods, recommended control measures, and information communicated about the zoonotic potential of canine giardiasis.

Toxoplasmosis is an important zoonotic disease worldwide caused by the intracellular parasite Toxoplasma gondii. Cats, being hosts, act as a good sentinel for this disease. Thus, the objective of this study was to determine the seroprevalence of T. gondii in cats by examining serum from seven districts of Metropolitan Lima, Peru.

Toxoplasmosis is a worldwide parasitic zoonosis caused by Toxoplasma gondii. Pigs can become infected by consuming water or food contaminated with sporulated oocysts, or by carnivorism (like the consumption of infected rodents). In pigs most infections are asymptomatic. In certain countries, pig meat containing tissue cysts is a major source of infection for human beings.

Toxoplasma gondii infects warm-blooded animals, including humans, and the ingestion of undercooked meat of infected animals is an important source of infection. We investigated the presence of T. gondii by PCR and histopathology in tissues of 25 seropositive sheep slaughtered for human consumption in Rio de Janeiro and assessed the suitability of different tissues for molecular detection of the parasite. The animals were first screened for T.

Cryptosporidiosis is an infection caused by a protozoon that inhabits the gastrointestinal tract. More than forty valid species have been described in the genus Cryptosporidium, infecting a broad range of hosts around the world, some with zoonotic transmission and others with predominant anthroponotic transmission.

A 70-day-old Boxer dog from a household in Montevideo, Uruguay, died after presenting neurologic, respiratory, and gastrointestinal signs for 6 days. Autopsy findings included lymphadenomegaly, ascites and hepatomegaly.

An analysis was made of the frequency of Cryptosporidium spp. in fecal samples from horses raised on farms in the Teresópolis city, state of Rio de Janeiro, Brazil, and the risk factors that favored this infection. Between 2019 and 2020, 314 samples of equine feces were collected, 287 of which came from English Thoroughbred horses and 27 from ponies.

The epidemiology of Cryptosporidium spp. in Latvia was investigated by testing fecal samples from 926 animals aged from one day to 24 years for the presence of Cryptosporidium spp. oocysts.
