Epidemiological aspects of the occurrence of anti-Sarcocystis spp. andanti-Toxoplasma gondii antibodies in dogs in the Northern region of Brazil

Rev. bras. ciênc. vet; 29 (4), 2022
We conducted aseroepidemiological study on the occurrence of anti-Sarcocystisspp. and anti-Toxoplasma gondii antibodies in dogs from family farming properties in the municipality of Ji-Paraná, Rondônia.Blood samples were collected from apparently healthy dogs between September 2012 and November 2013. I...

Cyclospora cayetanensis: diagnóstico de un coccidio poco frecuente en la Argentina
Cyclospora cayetanensis: diagnosis of a rare coccidium in Argentina

Resumen Cyclospora cayetanensis es un coccidio intestinal relacionado con brotes epidémicos debido al consumo de alimentos y agua contaminados con ooquistes esporulados. Predomina en regiones tropicales y subtropicales y puede causar síntomas gastrointestinales que son más graves en inmunocomprometido...

Prevalence of infection by Cryptosporidium spp. in calves and associated risk factors in Northeastern Brazil

Cryptosporidium spp. are zoonotic protozoa, frequently associated with diarrhea in calves, which are responsible for important economic losses. The aim of this study was to assess the prevalence of infection by Cryptosporidium spp. and its associated risk factors among calves raised in a milk production ...

Caracterização molecular de cistos de Giardia spp. e de oocistos de Cryptosporidium spp. recuperados de amostras de água de reúso

O aumento da demanda de recursos hídricos causado pelo crescimento da população mundial, pela necessidade de produção de alimentos e utilização na indústria é uma realidade. Como enfrentamento a este cenário de segurança hídrica, existe uma crescente tendência mundial de uso de águas recicl...

Copro-PCR in the detection and confirmation of Toxoplasma gondii oocysts in feces of stray and domiciled cats

Abstract Molecular methods such as Copro-PCR stand out in the diagnosis of T. gondii, because they are highly sensitive and specific, and can distinguish T. gondii from other morphologically similar coccids. The purpose was the detection of Toxoplasma gondii copro-prevalence by polymerase chain reaction ...

Techniques for inactivating Toxoplasma gondii oocysts: a systematic review

Abstract The oocyst, a resistant form of Toxoplasma gondii, plays an important role in the transmission of this protozoan. The objective of this review was to report the methods capable of inactivating oocysts through a systematic review of the literature carried out in the Scientific Electronic Library ...

Identification and Characterization of the ATG8, a Marker of Eimeria tenella Autophagy

Abstract Autophagy plays an important role in maintaining cell homeostasis through degradation of denatured proteins and other biological macromolecules. In recent years, many researchers focus on mechanism of autophagy in apicomplexan parasites, but little was known about this process in avian coccidia....

Evaluation of quantitative polymerase chain reaction for the detection of Toxoplasma gondii oocysts shed by cats

Abstract Felines are definitive hosts of Toxoplasma gondii and can shed oocysts in their feces, contaminating the environment. Sporulated oocysts are highly resistant to the environment and have higher infectivity, which are attributed to many toxoplasmosis outbreaks. The aim of the present study was to ...

DNA extraction methods for molecular detection of Eimeria spp. in cattle and sheep

Pesqui. vet. bras; 40 (7), 2020
Molecular detection of Eimeria species in fecal samples can be useful for experimental and diagnostic purposes. However, the parasite quantity presence in feces and the oocyst wall are an obstacle in DNA extraction protocols. Therefore, adequate sampling and effective disruption of the oocysts are essent...
