Abstract. Protozoa were present in routine sections of the gastric fundus of 15 cynomolgus monkeys (Macaca fascicularis) that were being studied in three toxicity studies with novel immunosuppressive agents. Upon detailed light microscopic and ultrastructural evaluation, all stages of parasite development (trophozoites, schizonts, gamonts, and oocysts) were seen and they structurally resembled ...

background : immunological response of host and parasite play a key role in developing vaccina­tion and immunization. the present study deals with the immune response and effecter mechanism, which was confirmed by migration inhibition factor (mif).  methods : the present work was conducted in parasitological lab of postgraduate department of zool­ogy, government holkar science college, indore (...

Numerous waterborne outbreaks of giardiasis have occurred since 1965, yet little or no information has been reported on the viability of Giardia cysts in different aquatic environments. We have studied the viability of Giardia muris cysts suspended in lake, river, and tap water, while also monitoring water temperature, dissolved oxygen, pH, and other water quality parameters. Fecal pellets cont...

After oral administration of cysts of the intestinal protozoan parasite, Giardia muris, young male C3H/He mice are chronically infected, whereas BALB/c mice demonstrate a rapidly resolving pattern of infection. Both strains of mice injected with trophozoites in adjuvant and challenged orally with cysts develop serum antibodies to numerous trophozoite proteins. A limited number of these protein ...

3450 bovine from different breeds and ages were clinically examined for the presence of arthritis. 120 cases showed macroscopic evidences of arthritis. Mycoplasma spp were isolated from synovial fluid of 21 affected animals. In addition to Mycoplasma spp. Arcanobacterium pyogenes and Staphylococcus epidermidis were isolated from 2 cases. The synovial fluid was markedly increased, straw color, t...

In a previous study, we have developed several chicken monoclonal antibodies (mAbs) against Eimeria acervulina (EA) in order to identify potential ligand molecules of Eimeria. One of these mAbs, 6D-12-G10, was found to recognize a conoid antigen of EA sporozoites and significantly inhibited the sporozoite invasions of host T lymphocytes in vitro. Furthermore, some of these chicken mAbs showed c...

BACKGROUND Majority of parasitic infections in rodents have zoonotic importance. This study aimed to determine the frequency and intensity of intestinal protozoa infections of rodents including Meriones persicus, Mus musculus and, Cricetulus migratorius. METHODS This survey was conducted in Meshkin Shahr district in northwestern Iran from Mar. to Dec. of 2014. Intestinal samples of 204 rodent...

We established a culture system for Entamoeba muris (MG-EM-01 strain isolated from a Mongolian gerbil) using a modified Balamuth's egg yolk infusion medium supplemented with 4% adult bovine serum and Bacteroides fragilis cocultured with Escherichia coli. Further, encystation was observed in the culture medium. The morphological characteristics of E. muris are similar to those of Entamoeba coli ...

Mycoplasma capricolum subspecies capricolum (Mcc) is one of the causative agents of contagious agalactia (CA), which is an important disease in sheep and goats in the Mediterranean and Middle East countries. Mycoplasma agalactiae is the classic agent of CA in sheep and goats. Mycoplasma mycoides subspecies Capri (Mmc), Mycoplasma capricolum subspecies capricolum (Mcc), and Mycoplasma putrefacie...
