Prevalence of Cysticercus tenuicollis in slaughtered sheep and goats by season, sex, age, and infected organ at Amol abattoir, Mazandaran province, Iran

Abstract Sheep and goats are the major sources of meat in Iran. The carcasses of 1,200 sheep and also 1,200 goats with their internal organs including the liver, diaphragm, and omentum from Amol abattoir were randomly inspected to estimate the prevalence rate of Cysticercus tenuicollis and asses its relationship with season, sex, age, and infected organs in slaughtered animals. A total of 2,400 animals (goats and sheep) was examined and 4.21 % was positive for C. tenuicollis. About 4.33 and 4.08 % of goats and sheep, respectively, were infected according to this survey; the difference of the prevalence of the parasite in these two species was not significant (P > 0.05). In both species (goat and sheep), the prevalence rate of cysts in female animals was higher than that in males; this outcome was highly significant (P

ConclusionThese results indicate that A. farnesiana pods contain nematocidal compounds and might be promising natural anthelmintic agents against H. contortus. This leguminous plant could be used as a nutraceutical food source for the control of gastrointestinal nematodes in small ruminants.Graphical abstract

Several studies have shown that invertebrates exhibit activity against various parasites, but no studies are available of effects of extracts of the sea urchin Echinometra mathaei on hydatid cysts. Here, E. mathaeis gonad extracts were investigated for t...

This study aimed to determine the prevalence of intestinal helminth parasitic infections and associated risk factors for the human infection among the people of Samarkand, Uzbekistan. Infection status of helminths including Echinococcus granulosus was surveyed in domestic and wild animals from 4 sites in the Samarkand region, Uzbekistan during 2015-2018. Fecal samples of each animal were examined with the formalin-ether sedimentation technique and the recovery of intestinal helminths was performed with naked eyes and a stereomicroscope in total 1,761 animals (1,755 dogs, 1 golden jackal, and 5 Corsac foxes). Total 658 adul...

In this study, mice were intraperitoneally infected with 10, 30 or 100 tachyzoites of T. gondii, respectively. Parasite infiltration and apoptosis in the spleen were analyzed on days 3, 7, and 9 post-infection by immunohistochemistry and flow cytometry. Significantly higher levels of T. gondii infiltration and apoptosis in the spleen were found in 30 and 100 tachyzoites infected mice compared to 10 tachyzoites infected mice on days 7 and 9 post-infection. Although 30 and 100 tachyzoites infected mice showed significant body weight loss compared to 10 tachyzoites infected mice, all of the 100, 30, and 10 tachyzoites infecte...

Authors: Ma DW, Lee MR, Hong SH, Cho SH, Lee SE Abstract Cryptosporidium parvum and Giardia duodenalis are the main diarrhea-causing parasitic pathogens; however, their prevalence in Korea is unknown. Here, we conducted a survey to determine the prevalence and genotype distribution of these 2 pathogens causing acute diarrhea in 8,571 patients hospitalized in 17 Regional Institute of Health Environment sites in Korea, during 2013-2016. C. parvum and G. duodenalis were detected and genotyped by nested PCR, and the isolate were molecularly characterized by sequencing the glycoprotein 60 (Gp60) and β-giardin genes...

In this study, PCR and nucleotide sequencing were performed to evaluate the genetic diversity and zoonotic potential of Blastocystis using pig fecal samples. We obtained 646 stool samples from groups of piglets, weaners, growers, finishers, and sows in Korea. A total of 390 Blastocystis-positive samples were identified, and the infection rate was 60.4%. The infection rates were significantly related to age and region. The 4 subtypes (STs) of Blastocystis confirmed by phylogenetic analysis were ST1, ST2, ST3, and ST5, indicating the high genetic diversity of Blastocystis in Korean pigs. ST5 was highly distributed in Korean ...

Authors: Wang W, Zhou X, Cui F, Shi C, Wang Y, Men Y, Zhao W, Zhao J Abstract Cystic echinococcosis (CE), a zoonotic disease caused by Echinococcus granulosus at the larval stage, predominantly develops in the liver and lungs of intermediate hosts and eventually results in organ malfunction or even death. The interaction between E. granulosus and human body is incompletely understood. Exosomes are nanosized particles ubiquitously present in human body fluids. Exosomes carry biomolecules that facilitate communication between cells. To the best of our knowledge, the role of exosomes in patients with CE is not reporte...
