The present investigation was carried out seasonally from October 2008 to September 2010, to study the impact of helminth parasites of catfishes of Lucknow. The fish fauna viz., Clarias batrachus, Heteropneustes fossilis, Wallago attu, Mystus vittatus and Rita rita were carried trematode, cestode, nematode and acanthocephalan parasites communities singly or mixed. The collected fish species inc...

present paper is the second publication introducing the paleoparasitological findings from animal coprolites obtained from archeological site of chehrabad salt mine in northwest-ern iran. the current archeological site is located in northwest of iran , dated to the sas-sanian era (4 th /5 th century ce).in the summer 2012 the carnivore coprolite was obtained within the layers in the mine and we...

The acanthocephalan parasite Pomphorhynchus laevis (Müller, 1776) uses freshwater amphipods as its intermediate host. In order to complete the life cycle, the infected amphipod must be consumed by a fish, where the acanthocephalan will mature and reproduce. Parasite transmission, and therefore fitness, could be enhanced if infected amphipods fail to detect or avoid predatory fish. We compared t...

The behavior of the cockroach Diploptera punctata parasitized with the acanthocephalan Moniliformis moniliformis was examined for parasite-induced alterations. No significant difference in behavior was found between parasitized and unparasitized animals in the following behavioral tests: (1) choice of white/black, horizontal/vertical substrate under light and dark conditions; (2) temporal and d...

Previously, we reported a tick recovered from Antelope Cave in extreme northwest Arizona. Further analyses of coprolites from Antelope Cave revealed additional parasitological data from coprolites of both human and canid origin. A second tick was found. This site is the only archaeological locality where ticks have been recovered. We also discovered an acanthocephalan in association with Entero...

Manipulation by parasites is a catchy concept that has been applied to a large range of phenotypic alterations brought about by parasites in their hosts. It has, for instance, been suggested that the carotenoid-based colour of acanthocephalan cystacanths is adaptive through increasing the conspicuousness of infected intermediate hosts and, hence, their vulnerability to appropriate final hosts s...
