Genotyping of Toxoplasma gondii and Sarcocystis spp. in road-killed wild mammals from the Central Western Region of the State of São Paulo, Brazil

CONCLUSIONS Our results indicate that T. gondii is commonly present in wild mammals, which act as sources of infection for humans and animals, including other wild species. The approach employed herein proved useful for detecting T. gondii and Sarcocystis spp. in the environment and identifying their natural reservoirs, contributing to our understanding of host-parasite interactions.

AbstractCystic echinococcosis is a potential zoonotic helminthic disease affect a broad spectrum of mammals including humans worldwide. The economic impact of the disease interestingly requires updated gathering information on the prevalence in slaughtered animals. Accordingly, in the current study, 573 camels, 4300 sheep, and 1235 pigs were surveyed in four Egyptian municipal abattoirs. Among those, 62 (10.82%) camels, 33 (0.77%) sheep and 3 (0.24%) pigs had cystic echinococcosis in lungs, livers and spleen. The diversity of cysts revealed that positive-cystic echinococcosis animals from all species were detected in El-Ba...

uimarães S Abstract The enteric protist Blastocystis is one of the most commonly parasite reported in humans and a variety of animal hosts worldwide. Regarding genetic diversity, at least 17 subtypes (STs) have been identified in mammals and birds, with eight of them (ST1-8) infecting both humans and animals. Recently, isolates from wild mammalian species have been genetically characterized, however data is still scarce, mainly in Latin America. Here, we aimed to verify the occurrence and genetic diversity of Blastocystis in captive wild mammals kept in one zoo and in two units of protection and conservatio...

MonjeAbstractThe current work evaluated road-killed Pampas foxes (Lycalopex gymnocercus) and their ticks for the presence of vector-borne agents in the ecoregion Esteros del Iberá in northeastern Argentina. Spleen, lung and blood samples and Amblyomma tigrinum adult ticks collected from the foxes were tested by polymerase chain reaction (PCR) assays targeting bacteria of the genera Ehrlichia, Anaplasma, and Rickettsia. All foxes...

o L, Maia C Abstract Cats have been found infected by the same Leishmania species that also infect dogs and humans in both the New and Old Worlds, and their role as additional reservoir hosts of L. infantum has been previously suggested. Currently, the genetic diversity of Leishmania spp. detected in cats is poorly understood. In this cross-sectional study, the partial nucleotide sequences of four gene markers (cytB, g6pdh, hsp70 and ITS-rDNA) were explored to investigate the genetic diversity and the phylogenetic relationships of Leishmania parasites detected in cats. A total of 25 cat buffy coat samples where th...

Abstract Giardia duodenalis is a cosmopolitan zoonotic protozoan parasite causing giardiasis, one of the most common diarrhoeal diseases in human and animals. Beyond its public health relevance, Giardia represents a valuable and fascinating model microorganism. The deep-branching phylogenetic position of Giardia, its simple life cycle and its minimalistic genomic and cellular organization provide a unique opportunity to define basal and "ancestral" eukaryotic functions. The eukaryotic 14-3-3 protein family represents a distinct example of phosphoserine/phosphothreonine-binding proteins. The extended netw...

In this study we analyze the distribution of apicomplexans across a range of both host-associated and free-living environments. Using publicly available small subunit (SSU) rRNA gene databases, high-throughput environmental sequencing (HTES) surveys, and our own generated HTES data, we developed an apicomplexan reference database, which includes the largest apicomplexan SSU rRNA tree available to date and encompasses comprehensive sampling of this group and their closest relatives. This tree allowed us to identify and correct incongruences in the molecular identification of apicomplexan sequences. Analyzing the diversity a...

This study was aimed to assess the eggs of gastrointestinal parasites of stray dogs and household dogs in lower Dir district, Pakistan with special consideration to those that can be spread to humans. One hundred and fifty two stool specimens from (stray dogs=90 and household dogs=62) were collected. The helminth eggs were processed by direct smear method and centrifugation techniques and identified by microscopic examination. Of the total examined dogs 26.8% (n=41 /152) were found to be infected with one or more intestinal parasites. The intestinal helminths detected were Dipylidium caninum (n =18, 11.8%), followed by Tox...

ConclusionOur findings indicate that cryptic myiasis cases due to the obligate parasite,C.bezziana, are under-recognized. Through this study onC.bezziana etiology, clinical features, diagnosis, treatment, epidemiology, prevention and control, we call for more vigilance and awareness of the disease from governments, health authorities, clinicians, veterinary workers, nursing homes, and also the general public.
