Source diversity of Artemia enrichment boosts goldfish (Carassius auratus) performance, β-carotene content, pigmentation, immune-physiological and transcriptomic responses.

This study aimed to assess the impact of spirulina and/or canthaxanthin-enriched Artemia on the goldfish (Carassius auratus) growth, pigmentation, blood analysis, immunity, intestine and liver histomorphology, and expression of somatolactin (SL) and growth hormone (GH) genes. Artemia was enriched with spirulina and/or canthaxanthin for 24 h. Goldfish (N = 225, 1.

Prevalence, Morpho-Histopathological Identification, Clinical Picture, and the Role of to Alleviate the Zinc Toxicity in .

The present context is a pioneer attempt to verify the ability of copepod, to uptake and accumulate heavy metals. We primarily assess the prevalence of the parasite in various seasons and its clinical signs, as well as post-mortem changes in (). The morphological features of the parasite using a light microscope, the bioaccumulation of heavy metals in the tissues of both and (gills, muscles) using Flame Atomic Absorption Spectrometry, and the histopathological alterations were monitored.

Sub-lethal effects of organophosphates and synthetic pyrethroid insecticides on muscle tissue transaminases of in vivo.

Organophosphates and synthetic pyrethroid insecticides have been commonly used in public health and agriculture. The present study aimed to evaluate the sub-lethal effects of organophosphates and synthetic pyrethroid insecticides on transaminases: glutamate oxaloacetate/aspartate transaminase (AST) and glutamate pyruvate/alanine transaminase (ALT) in . Fish were exposed to malathion (OP), chlorpyrifos (OP) and λ-cyhalothrin (synthetic pyrethroid) at sub-lethal concentrations of 1.

Phylogeny and ultrastructure of Kostoïngué, Fall, Faye and Toguebaye 1999, a newly recorded species infecting the ovaries of in Egypt.

The genus is the second largest within the class Myxosporea, which infects marine and freshwater fish. One hundred specimens were collected alive from a branch of the Nile River in Kafrelsheikh, Egypt. Microscopic and molecular procedures were used to describe how infects the ovaries of .

Morphologic and molecular identification of three macroscopic Sarcocystis species infecting domestic sheep (Ovis aries) and cattle (Bos taurus) in Egypt.

In a survey study on the macroscopic species of Sarcocystis infecting domestic sheep (Ovis aries) and cattle (Bos taurus) in Egypt, the macrosarcocysts of Sarcocystis gigantea and Sarcocystis medusiformis were detected in the carcasses of 33 domestic sheep out of a total of 250 (13.20%), whereas Sarcocystis hirsuta macrosarcocysts were found in 17 out of 150 cattle (11.33%) slaughtered at the municipal abattoirs of two different provinces in Egypt.
