“…It has been Tongue Liver Lungs Heart Kidneys Spleen mentioned in many studies (Khuroo, 2002;Eckert and Deplazes, 2004) that kidneys are among the organs with infection rates much lower than that of the liver and lungs (organ that favor this parasite). The preference of this organ (the kidney) as compared to others by the parasite may be due to several factors (possibly physical and chemical factors) that favored its development (Ehsan et al, 2017). Similarly, the high occurrence in the kidney could be due to the less sensitive para-clinical method used as compared to a more sensitive test like PCR which could have led to the identification of more cases and in other organs as compared to that obtained in the present study.…”

“…At that time, cysts were used to predict good and bad omen when screening the entrails of sacrificed animals (Battelli et al, 2002). Later, thanks to studies conducted by Galen (2 nd century BC), a great similarity was established between human cysts and those found in cattle (Ehsan et al, 2017). Echinococcosis is one of the most important helminthic diseases.…”

“…Indeed, animals are likely to be exposed to several zoonoses including echinococcosis (Bizuwork et al, 2012;Yang et al, 2005). This zoonosis is one of the human diseases known since antiquity (Ehsan et al, 2017).…”

Echinococcosis is an important zoonotic parasitic disease in Côte d'Ivoire and information on its occurrence at the Port-bouët abattoir is not yet documented. A retrospective study was carried out at the Port-Bouët abattoir from 2008-2015. A para-clinical examination of the isolated bovine organs (liver, kidneys, heart, lungs, tongues and spleen) for the presence of Echinococcus was carried out. There was a statistically significant difference with cases signaled per year with 2008 (10.55%) and 2015 (11.02%) recording the highest number of cases. Positive cases were only recovered from the kidneys. The present study provides baseline information about the echinococcosis situation at the abattoir-level and pave the way for future studies as well as in the implementation of control programs for this zoonosis in the South of Côte d'Ivoire.

“…The definitive hosts are dogs and other canids; while ungulates and other mammals act as intermediate hosts [3] such as sheep, goats, cattle, pigs, buffaloes, horses and camels [4]. The most common infection sites in cattle are the liver and lungs [5][6][7]. Within these viscera, a unilocular cyst forms, that will grow gradually from 1 to 5 cm a year [8].…”

New insights of the local immune response against both fertile and infertile hydatid cysts

et al. 2019

Background Cystic echinococcosis is caused by the metacestode of the zoonotic flatworm Echinococcus granulosus. Within the viscera of the intermediate host, the metacestode grows as a unilocular cyst known as hydatid cyst. This cyst is comprised of two layers of parasite origin: germinal and laminated layers, and one of host origin: the adventitial layer, that encapsulates the parasite. This adventitial layer is composed of collagen fibers, epithelioid cells, eosinophils and lymphocytes. To establish itself inside the host, the germinal layer produces the laminated layer, and to continue its life cycle, generates protoscoleces. Some cysts are unable to produce protoscoleces, and are defined as infertile cysts. The molecular mechanisms involved in cyst fertility are not clear, however, the host immune response could play a crucial role. Methodology/Principal findings We collected hydatid cysts from both liver and lungs of slaughtered cattle, and histological sections of fertile, infertile and small hydatid cysts were stained with haematoxylin-eosin. A common feature observed in infertile cysts was the disorganization of the laminated layer by the infiltration of host immune cells. These infiltrating cells eventually destroy parts of laminated layer. Immunohistochemical analysis of both parasite and host antigens, identify these cells as cattle macrophages and are present inside the cysts associated to germinal layer. Conclusions/Significance This is the first report that indicates to cell from immune system present in adventitial layer of infertile bovine hydatid cysts could disrupt the laminated layer, infiltrating and probably causing the infertility of cyst.

“…The genotypes have been related to the specific intermediate hosts including sheep, goats, horses, cattle, camels, pig, deer, elk, reindeer, moose and wapiti [16][17][18][19][20][21][22][23][24][25][26]. In humans, the disease is considered a deleterious health problem, while in animals infection may result in serious economic losses as the result of condemnations of affected organs in food animals [26,27].…”
