Morphometric and richness analysis of free-living and parasite taxa-invading street wetlands in Port Said, Egypt.

Background: Protists and helminths are considered the main organisms invading different cultures, especially aquatic organisms. Morphometric characteristics remain the most trustworthy descriptors of species identification or, more broadly, pattern recognition.

Aim: This study aimed to provide morphological descriptions of the most prevalent Protista and helminths found in various street wetlands in Port Said, Egypt.

Influences of parasitic stress on the health condition of African Catfish (Clarias gariepinus): Biochemical and histopathological alterations.

This study investigates the prevalence, severity, and impacts of parasitic infestations in Clarias gariepinus. Additionally, the study assesses the detrimental impacts of parasite infestation on the health condition of affected catfish, focusing on biochemical and histopathological alterations. A total of 160 fish were sampled from local markets.

Diplopstomiasis and acanthamoebiasis syndromes in the different organs of Oreochromis aureus collected from Lake Manzala.

Background: is a member of the tilapia family that is considered one of the main food sources in different countries all over the world.

Aim: Thus, studying the different pathogens infecting tilapia species is still one of the interesting search points.

Methods: One hundred and eighty specimens of were collected from Lake Manzala and transported directly in iceboxes to the laboratory of the faculty of Science at Port Said University.

Effect of vitamin C injections on exercise muscular performance and biochemical parameters in -infected mice.

Background: is a worldwide intestinal nematode that can parasitize the striated muscles of its hosts at the larval stage. This study aims to evaluate potential of vitamin C for treating trichinellosis-related pathological problems in the infected muscles of mice.

Materials And Methods: Thirty CD1 male Albino mice were divided into three groups (10 mice per group).

Seasonal fluctuations of heavy metal accumulation and gastrointestinal helminth induce oxidative stress and histological lesions in resident catfish Clarias gariepinus.

The exposure of the African catfish (Clarias gariepinus) to various environmental contaminants leads to physiological and histological alterations. Therefore, the study aimed to assess the impact of seasonal variations of ecological contaminants as external stressors and internal stressors via helminth infections on oxidative stress and histopathology in resident C. gariepinus at EL-Salam Canal, Egypt.

Parasitological and Biochemical Efficacy of the Active Ingredients of and in Infected Mice.

The active ingredients allicin and curcumin have a wide range of actions against fungi, bacteria, and helminths. Therefore, the study was aimed to evaluate the efficacy of allicin (AL) and curcumin (CU) as antischistosomal drugs and their biochemical effects in normal and -infected mice. Praziquantel (PZQ) was administrated for two successive days while AL or CU was given for two weeks from the week 7th postinfection (PI).

The in Vitro Antischistosomal Activity and Genotoxicity of the Active Ingredients of (allicin) and (curcumin).

Background: In this study, we assessed the in vitro antischistosomal activity of the active ingredients of (allicin) and (curcumin) on .

Methods: This study was conducted in Faculty of Science, Port said University, Egypt (2018). Adult worms were exposed to a range of concentrations of AL or CU, and worm survival was assessed 24 h post-exposure to calculate the lethal concentration of the compounds.
