Immunoprotective responses against murine sarcocystosis by β - Irradiated sporocysts.

This study aimed to induce protective immunity against infection with Sarcocystis muris in experimental mice using β-irradiated sporocysts. Mice were vaccinated with 50 sporocysts of S. muris which were exposed to 1.

Influence of Moringa oleifera extract, vitamin C, and sodium bicarbonate on heat stress-induced HSP70 expression and cellular immune response in rabbits.

The current study aimed to test the effect of Moringa oleifera extract (MOE), vitamin (Vit) C, and sodium bicarbonate (NaHCO) on heat stress (HS)-induced alterations in rabbits. Five groups of rabbits were designed as control, HS, HS + MOE, HS + Vit C, and HS + NaHCO. HS groups were exposed to high temperatures, while treatments were given in drinking water for 6 weeks.

Gene expression, oxidative stress and apoptotic changes in rabbit ileum experimentally infected with Eimeria intestinalis.

Coccidiosis is a parasitic disease caused by protists (apicomplexans) of the genus Eimeria Schneider, 1875 and is considered to be the most important disease faced by rabbit breeders due to its high morbidity. In the present study, the antioxidant status and changes in apoptosis and in the expression of some genes were quantified in rabbits' ilea following infection with Eimeria intestinalis Cheissin, 1948. Rabbits, orally infected with 1 × 10 sporulated oocysts of E.

Detection for cross-reactive proteins in filarial worm Setaria equina, MCF-7 human breast cancer, and Huh-7 hepatoma cells.

This study aimed to detect the cross-reactive proteins in filarial parasite adult worm Setaria equina and two different tumor cell lines (MCF-7 human breast cancer and Huh-7 hepatoma cells). This was performed using rabbit anti-S. equina extract (SeqE) or DEC (Diethylcarbamazine citrate) polyclonal IgG antibodies by indirect ELISA and western blotting.

A new record of Myxobolus brachysporus and M. israelensis in the tilapia (Oreochromis niloticus) collected from the Nile River, Egypt.

The present study was carried out as part of an ongoing general survey for myxosporean parasites infecting tilapias in the River Nile, Egypt. In the present study, 77 Nile tilapia (Oreochromis niloticus) were collected from boat landing sites at Beni-Suef governorate, Egypt and examined for the myxosporean infection. The infection was encountered as a huge number of free spores in the kidney and the spleen.

Re-description of Myxobolus fahmii from the gills of Barbus bynni with new data on the precise infection site, histological impacts, and seasonality.

Originally, Myxobolus fahmii was described from the gills of Barbus bynni collected from the Nile River, Egypt. The original study provided only mensural characteristics of the spores and referred to gill lamellae as the site for the infection. In this study, B.

Pfeifferinella sp. (Pfeifferinellidae, Apicomplexa) infecting the fresh water snail Pirenella conica light and electron microscope studies.

Coccidian oocysts were proved to be found in 70 of 100 collected Pirenella conica snails, with a natural infection of 70%. It was observed that, Pfeifferinella sp. was transferred between hepatopancreas and small intestine of snail.

Two Myxobolus spp. infecting the kidney of Nile tilapia (Oreochromis niloticus) in the River Nile at Beni-Suef governorate, Egypt, and the associated renal changes.

Two Myxobolus spp. are described from the kidney of the Nile tilapia (Oreochromis niloticus) collected from the River Nile, Egypt. The prevalence of infection was 61 % (47/77), with the infected fish in each case parasitized by the two Myxobolus species simultaneously.

Immunomodulatory effect of diethylcarbamazine citrate plus filarial excretory-secretory product on rat hepatocarcinogenesis.

Diethylcarbamazine citrate (DEC) had a significance in anti-filarial chemotherapy, while excretory-secretory product (ES) is released from adult filarial females. The target of the current study was to examine the immunomodulatory effect of DEC, Setaria equina ES or a combination of them on rat hepatocellular carcinoma (HCC) induced by diethylnitrosamine (DEN). In vitro effect of combined DEC and ES or ES alone on lipopolysaccharide (LPS)-stimulated rat peripheral blood mononuclear cells (PBMCs) was tested through IFN-γ assay in culture supernatants.

Effect of diethylcarbamazine citrate and Setaria equina excretory-secretory material on rat hepatocellular carcinoma.

Diethylcarbamazine citrate (DEC) has been known for its efficacy to eradicate bancroftian filariasis in Egypt and other countries in the world. One of the known effects was to decrease the level of circulating filarial antigen in the patient's serum. The target of this study was to examine the effect of DEC, excretory-secretory (ES) material from the filarial parasite Setaria equina or a combination of both on the status of oxidative stress and pathogenesis of rat hepatocellular carcinoma (HCC) induced by diethylnitrosamine and 2-acetylaminofluorene.

Seasonal fluctuation and histopathology of Henneguya ghaffari (Myxozoa: Myxosporea) infection in the gills of the Nile perch, Lates niloticus, in the River Nile: a new locality record.

Henneguya ghaffari Ali (Dis Aquat Org 38:225-230, 1999), which was originally described in Lake Wadi El-Rayan in the western desert of Egypt, has been discovered in the gills of the Nile perch, Lates niloticus, sourced from the River Nile at Beni-Suef governorate. The species identification was based on the spore morphometry. Of 180 Nile perch, 68 were found to be naturally infected with H.

Evaluation of a 14.5 kDa-Fasciola gigantica fatty acid binding protein as a diagnostic antigen for human fascioliasis.

The aim of the present study was to evaluate the efficiency of 14.5 kDa-Fasciola gigantica fatty acid binding protein (FABP) as a diagnostic antigen for human fascioliasis. 14.

Lambs infected with UV-attenuated sporocysts of Sarcocystis ovicanis produced abnormal sarcocysts and induced protective immunity against a challenge infection.

The present study surveyed the prevalence of natural infection of the sheep esophagus muscle with sarcocysts of Sarcocystis ovicanis and examined induction of protective immunity using UV-attenuated sporocysts. The overall prevalence of natural infection of the sheep was 95%. Infectivity of the collected sarcocysts was confirmed by shedding of sporulated oocysts after feeding infected esophageal tissues to dogs.
