Immune response, oxidative stress, and histological changes of Wistar rats after being administered with Parascaris equorum antigen.

Worldwide, particularly in developing nations, helminth infections are the leading causes of livestock illness and mortality. Parascaris (P.) equorum, a parasitic worm from the Ascarididae family, significantly impacts the production, health, and working performance of equines.

Potential anthelmintic effect of chitosan on Syphacia muris infecting Wistar rats: biochemical, immunological, and histopathological studies.

Natural products extracted from animal sources have many biological activities, such as chitosan, which is being researched for its medicinal or therapeutic potential. Syphacia muris is the most well-known intestinal nematode, infecting laboratory rats and influencing their immune systems. In this study, we looked at the anthelminthic activity of chitosan particles against S.

In vivo efficacy of silver nanoparticles against infected laboratory Wistar rats.

Helminth infections are a worldwide problem that affects both humans and animals in developing countries. The common pinworm frequently infects lab rats and can obstruct the creation of unrelated biological experiments. The objective of this study was to examine the in vivo efficacy of silver nanoparticles against infected Wistar rats.

Morphological and molecular identification of third-stage larvae of Anisakis typica (Nematoda: Anisakidae) from Red Sea coral trout, Plectropomus areolatus.

Anisakidosis is a foodborne zoonotic infection induced by members of the family Anisakidae via the consumption of raw or undercooked fish such as sushi and sashimi. Identifying anisakid larval species is critical for the epidemiology and diagnosis of diseases caused by them. This study aimed at identifying Anisakis larvae collected from marine fish in Egyptian waters based on morphological characteristics and molecular analysis.

New host records of three juvenile nematodes in Egypt: Anisakis sp. (Type II), Hysterothylacium patagonense (Anisakidae), and Echinocephalus overstreeti (Gnathostomatidae) from the greater lizard fish Saurida undosquamis of the Red Sea.

Three juvenile nematode parasites were collected naturally from 90 (75 %) out of 120 specimens of the marine greater lizard fish Saurida undosquamis captured from water coasts at Hurghada City along the Red Sea in Egypt during the period from September 2013 to April 2014. Worms were identified on the basis of light and scanning electron microscopy. Two of the recovered worms were isolated from the peritoneal cavity of the infected fish around the wall of the stomach as encapsulated larvae.

First identification of four trypanorhynchid cestodes: Callitetrarhynchus speciouses, Pseudogrillotia sp. (Lacistorhynchidae), Kotorella pronosoma and Nybelinia bisulcata (Tentaculariidae) from Sparidae and Mullidae fish.

Four previously unrecognized trypanorhynchids are described based on fish specimens from Sparidae and Mullidae host fish of the Red Sea. From September 2010 to June 2011, 66 specimens of the sea bream Pagrus pagrus (F: Sparidae) and 43 of the red mullet Mullus barbatus (F: Mullidae) were purchased from markets in the Suez and Hurghada cities of the Red Sea. The fishes were measured, and their organs investigated for helminth infections.

New host and locality records of two nematode parasites Dujardinnascaris mujibii (Heterocheilidae) and Hysterothylacium aduncum (Anisakidae) from the common seabream Pagrus pagrus: a light and scanning electron microscopic study.

In the present study, the morphology and morphometric characterization of Dujardinnascaris mujibii (Heterocheilidae) and Hysterothylacium aduncum (Anisakidae), new nematode parasites infecting the sea bream Pagrus pagrus (Osteichthyes, Sparidae), were described for the first time from the Gulf of Suez and Hurghada City of the Red Sea, Egypt. Ninety-eight (70 %) and 62 (44.2 %) out of 140 of the examined fish were naturally infected with these nematodes, respectively.

First record of anisakid juveniles (Nematoda) in the European seabass Dicentrarchus labrax (family: Moronidae), and their role as bio-indicators of heavy metal pollution.

This study assessed the anisakid nematode distribution pattern in the fish collected from coasts of Mediterranean Sea, Egypt, during the period September 2010-April 2011. Two hundred thirty out of 300 (76.7%) Dicentrarchus labrax (European seabass) marine fishes belonging to family Moronidae were dissected and found to be infected with larva three nematodes.
