OBJECTIVE In this study, we aimed to determine the parasite species carried by hamsters and rabbits purchased from some commercial pet shops in Turkey. METHODS For this purpose, the fecal samples of clinically healthy Syrian hamsters, dwarf hamsters, and crossbred rabbits were collected from 22 pet shops randomly selected in Ankara and Kirikkale provinces, located in Central Anatolia Region o...
Background: Parasitic diseases are one of the most common infections among school-aged children that have severe side effects such as anemia, delayed growth, and mental retardation. One of the ways to prevent the disease is personal hygiene, This study aimed to evaluate the fingernails parasitic infection in children before entering school. Materials and methods: In this cross-sectiona...
Cleaner organisms exhibit a remarkable natural behaviour where they consume ectoparasites attached to "client" organisms. While this behaviour can be utilized as a natural method of parasitic disease control (or biocontrol), it is not known whether cleaner organisms can also limit reinfection from parasite eggs and larvae within the environment. Here we show that cleaner shrimp, Lysmata amboine...
Hosts of obligate avian brood parasites use visual cues to distinguish between their own eggs and those of the parasite. Despite major differences between human and bird vision, most previous studies on cuckoo egg mimicry estimated color matching based on human color vision. Undetected by humans, ultraviolet reflectance (UVR) may play a previously ignored role for rejection behavior in avian br...
Avian brood parasites lay their eggs in the nests of other birds, and impose the costs associated with rearing parasitic young onto these hosts. Many hosts of brood parasites defend against parasitism by removing foreign eggs from the nest. In systems where parasitic eggs mimic host eggs in coloration and patterning, extensive intraclutch variation in egg appearances may impair the host's abili...

Parasites and intestinal worms are one of the main causes of the economic decline in the sheep industry. This research carried out for consideration of microsatellite polymorphism in the intron 5 of DRB2 gene and its association with the egg numbers of Marshallagia Marshalli parasite in Ghezel sheep breed, Blood and fecal samples were obtained from 80 male lambs at the age of 4-6 months. Fecal...
Parasite findings in sambaquis (shell mounds) are scarce. Although the 121 shell mound samples were previously analysed in our laboratory, we only recently obtained the first positive results. In the sambaqui of Guapi, Rio de Janeiro, Brazil, paleoparasitological analysis was performed on sediment samples collected from various archaeological layers, including the superficial layer as a control...
