“…Many techniques were used against infestation with hydatid disease in experiential animals, such as irradiation with laser, direct electrical current, probiotics and ultrasound (31)(32)(33)(34)(35)(36)(37), all techniques revealed considerable influence to the disease. All the techniques exhibited valuable efficiency against protoscoleces in vitro and cystic echinococcosis in mice.…”

This study determined the influence of selenium nanoparticles on the vitality of the protoscoleces of Echinococcus granulosus in vitro; seven concentrations were used: 50, 100, 150, 200, 250, 350, and 500 µg/ml for different exposure times: ten, twenty, thirty, and sixty minutes, respectively. Albino mice Mus musculus were injected with protoscoleces exposed to nanoparticles at 100, 150, and 200 µg/ml concentrations for 60 minutes. In contrast, control groups were injected with non-exposed protoscoleces. Mice were dissected three, four-, and five-months post infestation. Many criteria were relied on: numbers, weights, diameters of growing hydatid cysts, and their reduction proportion. The outcomes uncovered an apparent influence of selenium nanoparticles on the viability of protoscoleces of Echinococcus granlosus by the increase in exposure time in vitro, as well as diminish in the numbers of the larvae in processed mice versus the unprocessed collection; no cysts evolved inside processed mice at the concentration 200 µg/ml, threeand four-months post-infection. In contrast, the reduction rate was 90% in mice injected with exposed protoscoleces at the concentration of 150 µg/ml next 4 and 5 months of infection.

“…In Iran abattoirs, Pezeshki reported that; the prevalence of E. granulosus parasite's larva stage or hydatidosis disease which is a remarkable silent zoonotic helminthic malady infection in intermediate hosts warm-blooded vertebrates as cattle and sheep which is 2.25% and 2.48%, respectively and what is worth to mention the definitive host includes carnivores such as the canidae and felidae families such as dogs, foxes and hyenas, according to a survey created for the period 2015 -2018, (12,13) The overall prevalence in Pakistan during the period 2000 -2020 is 18.1%, with the highest infection in sheep 53.5%, followed by goats 44.9%, cows 21.3%, buffaloes 16.8%, and cattle 12.7% (14,15). In slaughtered sheep and goats in Amol abattoir, Mazandaran, northern Iran, the prevalence rate of Fasciola spp was 6.6% (16,17). The infection rates of the Fasciola parasite in sheep in Jeddah, Saudi Arabia, is higher among the imported sheep 1.19% than local slaughtered sheep 0.27% in the period 2019-2020 (18,19).…”

Gastrointestinal parasites, such as helminths and protozoa, are abundant parasitic agents of livestock, particularly ruminants. The current study aims to determine the prevalence rate of parasitic infections in large ruminate animals slaughtered in the mechanical abattoir in Alexandria governorate, Egypt. The prevalence was identified through the records of parasitic infections detected in the fecal matter of large ruminate animals in addition to the recorded postmortem examination findings. Three hundred sixty-four slaughtered large ruminant animals were selected, labeled, and subjected to fecal sampling and postmortem examination. Each fecal sample was tested by three different techniques; the formalin-ether concentration, Ziehl-Neelsen hot-stained, and saturated saline flotation to diagnose all parasite types. One hundred thirty positive cases (35.71%) were determined during the fecal sample examination, and 76 cases (20.87%) were found in postmortem examination. Formalin-ether processing of fecal samples yielded the highest number of pathogens; Entamoeba species were detected in 98 fecal samples (26.69%), and Fasciola species eggs were detected in 14 samples (3.84%). The postmortem examination revealed Fasciola hepatica and F. gigantica in 13 animals (3.57%), mixed lung and liver hydatid cysts in 32 animals (8.79%), whereas liver hydatid cysts only were identified in 15 animals (4.12%). Finally, Sarcocystosis infection was detected in 3.57%. In conclusion, the parasitic infections of large ruminant animals are a leading cause of pathogenicity in large animals, leading to economic losses. Prevention and control measures must be implemented by mechanical abattoirs according to the hazard analysis critical control point system.
