This is the first record of the nematode parasite Kalicephalus subulatus (Strongylida, Diaphanocephalidae) in Wagler’s snakes, Xenodon merremi (Squamata, Colubridae), collected in Corrientes, Argentina. The species was observed using light and scanning electron microscope (SEM) and compared to previous studies from Tropical America. As for the metric characters, the specimens collected in Argentina are smaller than all of those found so far in other hosts. However, despite the differences in the measurements, some characters such as the dorsal lobe type III and the amphidelphic uterus allow its specific identification...

Bartonellosis is a disease caused by Bartonella spp. microorganisms which belong to the Rickettsiales order. This disease is a zoonosis, B. henselae, whose primary reservoir is the cat, which in humans causes a cat-scratch disease. In infected cats, symptoms such as fever, lymphedema, reproduction disorders, myocarditis, rhinotracheitis, gingivitis, and arthritis may be observed. Bartonella appears to be transmitted among cats and dogs in vivo exclusively by arthropod vectors (excepting perinatal transmission), not by biting or scratching...

Amoebas from the genus Acanthamoeba are cosmopolitan organisms, which can exist as free-living organisms and as parasites within host tissue. Acanthamoeba infection present a serious risk to human health and are characterized by high mortality, especially in immunocompromised individuals. These protozoa are the etiological factors of granulomatous amoebic encephalitis (GAE) and Acanthamoeba keratitis (AK). They can also live in the lungs, adrenals glands, nose, throat, and bones of the host. Furthermore, the amoebas can be vectors of pathogenic bacteria...

In the Central European conditions, three species of Babesia have epidemiological significance as human pathogens – Babesia divergens, B. microti and B. venatorum. Tick Ixodes ricinus is considered as their main vector, wild mammals as the animal reservoir. The zoonotic cycles of small and large Babesia differ in details. Due to the lack of transovarial mode transmission in small species B. microti, the circulation goes mainly between immature ticks and vertebrate hosts; pathogen circulates primarily in the cycle: infected rodent → the tick larva → the nymph → the mammal reservoir →the larva of the tick...

Acanthocephalan larvae were found during parasitological sections in intestines of four out of 84 individuals of raccoon (Procyon lotor L.) from eastern Czech Republic. They were identified as cystacanths of Polymorphus minutus (Goeze, 1782). Because water birds are the proper hosts of this parasite, this record is among the rare ones. For this reason we present the morphological description, biometric data and photographs of the parasites, as well as a discussion of similar cases reported in the literature...

Toxoplasma gondii is a common protozoan parasite which causes toxoplasmosis worldwide. There are limited treatment options against T. gondii infection. Once transmitted, T. gondii can spread to many organs in the body, including the brain, liver and kidneys. One of the most common signs of toxoplasmosis is a rise in oxidative stress. Therefore, our aim was to determine the antioxidant levels in the brain, liver and kidney of rats infected with this parasite. In the present study, 2–4-months old Wistar albino rats were infected intraperitoneally with 1 x 104 mL of RH strain of T...
