Tracking acute phase protein response during acute and chronic infection.

Toxoplasmosis is a disease caused by the protozoan , which occurs worldwide in mammals and birds. Brain is the primary target organ because is a ubiquitous intracellular parasite that causes most frequently life-threatening encephalitis in immunocompromised patients. Relation of tissue cysts number, histopathology score and acute phase proteins were investigated.

Role of stellate cells in hepatic echinococcosis in cattle.

Hydatid cysts formed by the metacestodes of . Cattle suffering from hydatid cyst shows fluid-filled structures, especially in liver. These parasite-induced cysts localized by forming fibrous capsules in the liver.

Role of NETs in the difference in host susceptibility to Toxoplasma gondii between sheep and cattle.

The main aim of this study was to compare extracellular traps (NETs) formation by polymorphonuclear neutrophils (PMNs) of cattle and sheep when exposed to T. gondii tachyzoites in vitro. The effects of parasite concentrations and different incubation periods on NETs development in cattle and sheep PMNs were studied.

Hepatic stellate cells increase in Toxoplasma gondii infection in mice.

Background: Toxoplasma gondii is a ubiquitous protozoan parasite that can infect humans and animals. The severity of toxoplasmosis varies according to the immune status of the individual, parasite strain, and host species. In mammalian species, it has been observed that severe lesions of acute toxoplasmosis form in visceral organs such as the liver, lung, and spleen.

[Ticks and transmission of some important diseases by ticks].

Ticks which are commonly found all around the world are ectoparasites which are obliged to suck blood from vertebrates such as mammals and birds during all of their periods of develeopment. They may cause toxicities and paralyses in the course of blood sucking through saliva injection and the attachment sites may become ports of entry for secondary agents. Healthy animals that are severely infested by ticks can show a decreased yield and anemia.

[Investigation of the prevalence of visceral leishmaniasis by the microculture method and IFAT in dogs in Kirikkale.].

This study was carried out in order to compare the seroprevalence of visceral leishmaniasis in dogs from different areas of Kirikkale between 2006-2008 using the microculture method (MCM) which is a new method, and the indirect fluorescent antigen test (IFAT). All of the blood collected from total of 50 dogs was found to be negative by MCM. Only one male Beagle strain dog (3 years old) was found to be seropositive at 1/128 titers (2%) for anti-Leishmania infantum IgG antibodies by IFAT.
