Complications of parasite infections, especially kidney disease, have been linked to poorer outcomes. Acute kidney damage, glomerulonephritis, and tubular dysfunction are the most prevalent renal consequences of infection. The purpose of this study was to determine the pharmacological effects of green-produced zinc oxide nanoparticles (ZnO NPs) on infection in male Wistar rats.
View Article and Find Full Text PDFMain Conclusions: Green-synthesized zinc oxide nanoparticle is a promising treatment modality against parasitic infection through its powerful anthelmintic, antioxidant, healing promotion, and anti-inflammation effects.
Background: Nanoparticles have many properties, depending on their size, shape, and morphology, allowing them to interact with microorganisms, plants, and animals.
Objectives: Investigation of the therapeutic effects of green-synthesized zinc oxide nanoparticles (ZnO NPs) on Parascaris equorum infection in rats.
is a common gastrointestinal nematode of buffaloes and cattle, primarily young calves. This parasitic infection is distributed worldwide, causing a huge economic loss due to reduced meat and milk production and animal mortality. Several studies have indicated that silver nanoparticles have an effective anthelmintic activity.

Methods: Different concentrations of ZnO NPs (100, 200, 300 and 400 mg/l) synthesized using the egg white were prepared followed by the incubation of parasitic worms with these concentrations in vitro.
During a survey of myxosporean parasites infecting freshwater fishes from the River Nile at Giza Governorates, Egypt between March and September 2016, nine out of 30 specimens of the Nile carp Labeo niloticus (Cyprinidae) were found to be naturally infected with Myxobolus naffari (Myxobolidae). Small macroscopic plasmodia appeared embedded in the host gill tissue accompanied with fusion of the gill epithelia, and atrophy was observed at the site of infection. The host reaction was manifested by the encapsulation of the plasmodia with a thick layer of connective tissue.

Infection was detected as opaque white or rusty brown lesions scattered throughout the musculature of the fish mainly in the region anterior to anus. Transmission electron microscopy showed that in individual parasitized muscle cells, the infection progresses within parasite formed vesicles which are in direct contact with muscle cell elements.

Ten out of fifty six (17.9%) of the examined specimens were infected with Oochoristica.

High ssurRNA sequence similarity (> or =99%) and the resulting phylogeny demonstrated that S.

The efficacy of Mirazid (Commiphora molmol or Myrrh) was evaluated in sheep naturally infected with fascioliasis. Total doses of one or two capsules (300 mg each) were given for one, two or three successive days on an empty stomach an hour before breakfast. A total dose of 600 mg gave a cure rate of 83.

The ascaricidal efficacy of six commonly used traditional herbs. Artemesia santonica, Inula helenium, Cassia abutnsifolla, Albizzia lebbek, Acacia auriculoformis and oil of Apium graveolens, was tested in vitro against the eggs and larvae of Ascaris lumbricoides. Aqueous extracts of 1% Artemesia and 5% of Albizzia and Inula were effective in killing both the infective larvae ill less than 40 days and eggs in 20 days.
