Vet Sci 2023; 10:520. [PMID: 37624307 PMCID: PMC10458481 DOI: 10.3390/vetsci10080520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/03/2023] [Accepted: 08/09/2023] [Indexed: 08/26/2023] Open
Abstract
Contradictory data is available on the intermediate host specificity of Sarcocystis spp. in farm animals. Therefore, the current work aimed at molecularly testing samples of sheep and goats reared in Lithuania to identify Sarcocystis species described in other intermediate hosts but suspected to be non-canonical parasites to these small ruminants. For this purpose, muscle samples from 47 domestic sheep and nine goats were examined. Sarcocystis species were identified using direct and nested PCR targeting cox1 and sequencing of positive amplified products. Along with the detection of the canonical Sarcocystis spp. in their respective intermediate hosts, the DNA of S. capracanis and S. morae was detected in sheep, although these species were previously thought to be specific to goats and deer, respectively. In addition, DNA from S. arieticanis and S. tenella was found in goats, even though these two species were believed to be sheep-specific. Notably, under light microscopy, only sarcocysts of S. capracanis specific to goats were observed. Thus, future research on the life cycle and host-specificity of Sarcocystis spp. examined is warranted.

Feng Y, Guo R, Sang X, Zhang X, Li M, Li X, Yang N, Jiang T. A Systematic Meta-Analysis of Global Sarcocystis Infection in Sheep and Goats. Pathogens 2023; 12:902. [PMID: 37513749 PMCID: PMC10386720 DOI: 10.3390/pathogens12070902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 06/21/2023] [Accepted: 06/27/2023] [Indexed: 07/30/2023] Open
Abstract
Sarcocystosis is an intracellular parasitic disease caused by Sarcocystis spp. that has a worldwide prevalence. Symptoms of the disease include diarrhea and muscle pain. The disease poses a threat to the health of animals. The aim of this review is to investigate the global prevalence of Sarcocystis infection in sheep and goats during 2013-2022. We searched five databases: Web of Science, Science Direct, PubMed, Scopus, and Google Scholar. A total of 36 articles containing 44 datasets met the criteria and were included in the study. The total infection rates of Sarcocystis in sheep and goats were 66.3% (95% CI, 51.79-79.38%) and 52.1% (95% CI, 29.45-74.23%), respectively. It was found that Sarcocystis species tend to have a host species preference. Coinfection of S. tenella and S. arieticanis often occurred in sheep, and goats were frequently infected with S. capracanis. Age and sex were identified as risk factors for Sarcocystis infection in sheep and goats. The infection rates of female and male animals were significantly different, with females having a higher infection rate. Age-adjusted analysis showed that infection rates in animals older than one year were higher than in animals younger than one year. This study unveiled the global distribution of Sarcocystis and sheds light on its transmission in sheep and goats.

Molecular Characterization of Sarcocystis Species Isolated from Sheep and Goats in Riyadh, Saudi Arabia. Animals (Basel) 2019; 9:ani9050256. [PMID: 31117222 PMCID: PMC6562545 DOI: 10.3390/ani9050256] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Revised: 05/07/2019] [Accepted: 05/18/2019] [Indexed: 11/17/2022] Open
Abstract
Simple Summary In this article, we investigated the occurrence of Sarcocystis species in samples of sheep and goats obtained from slaughterhouses in Riyadh, Saudi Arabia. We searched for tongue, heart, esophagus, diaphragm and skeletal muscle tissues. Fragments of these tissues were investigated by macroscopic evaluations, direct optical microscopy of tissue fragments, optical microscopy of digested fragment sediment, transmission electron microscopy and PCR followed by nucleotide sequencing. From the set of information obtained, we searched 230 sheep, and 84 goats; 91 and 36 were found to be infected, respectively. Transmission electron microscopy (TEM) revealed Sarcocystis tenella (S. tenella) in sheep and Sarcocystis capracanis (S. capracanis) in goats. Sarcocystis species were confirmed in Saudi Arabian sheep and goats by molecular testing. S. capracanis was most closely related to S. tenella, with the mitochondrial cytochrome c oxidase subunit I gene (COX1) sequences sharing a (91.7%) identity. Abstract Sarcocystosis is induced by species of Sarcocystis, which is an intracellular protozoan parasite in the phylum Apicomplexa. The diversity and importance of Sarcocystis species in sheep and goats in Saudi Arabia are poorly understood. In this study, the tongue, esophagus, heart, diaphragm, and skeletal muscles were collected from 230 sheep and 84 goats, and the tissues were examined for the presence of Sarcocystis species by macroscopic examination and light microscopy. Microscopic Sarcocystis species cysts were found in both sheep and goats. Transmission electron microscopy (TEM) revealed S. tenella in sheep and S. capracanis in goats. Sarcocystis species were confirmed for the first time in Saudi Arabian sheep and goats by molecular testing. S. capracanis was most closely related to S. tenella, with the COX1 sequences sharing 91.7% identity. A phylogenetic analysis produced similar results and indicated that the Sarcocystis isolates were within a group of Sarcocystis species in which dogs were the final host. Finally, the Sarcocystis species cysts from sheep and goats could be grouped together, indicating that they were strongly related.

VETERINARY PARASITOLOGY- REGIONAL STUDIES AND REPORTS 2018; 13:193-197.

Abstract
In order to explain the exact role of sarcocystosis, principally Sarcocystis tenella, in losses of the Egyptian sheep industry, a precise confirmation about the existence of different Sarcocystis species infecting that economically important animal is needed. Therefore, this work aimed to molecularly identify, as well as illustrate the genetic variability within isolates of Sarcocystis spp. infecting sheep from Egypt. Tissue specimens were collected from sheep slaughtered at 3 Egyptian provinces; Cairo, Dakahlia and Damietta. DNA was isolated from the harvested bradyzoites after peptic digestion for the positive sarcocysts infected specimens, and then PCR amplification using the 18S rRNA gene was carried out. PCR products were subjected to gel electrophoresis. DNA from 600 bp gel bands was purified and sequenced. The revealed sequences were compared to their similarities on Genbank, and analyzed both clusterally and phylogenetically. Two Sarcocystis spp. were identified, the macroscopic cyst forming S. gigantea and the microscopic cyst forming S. tenella. Nine S. tenella sequences were analyzed, resulting in 3 polymorphic sites as well as 3 different haplotypes. Clustering of the nine obtained S. tenella sequences in addition to another 23 S. tenella sequences on Genbank revealed low nucleotide (0.001780) diversity as well as negative value of the Taijma neutral index which are indicators for population expansion. Alignment and Phylogeny results illustrated very close relationship between S. gigantea and S. moulei, a goat specific species which rarely reported in sheep, and in turn proposed the cross transmission of the later species between sheep and goats.
