Introduction Parasites play important roles in ecosystems. Through their interactions with host and vector species, they are capable of changing the behavior population dynamics shape entire communities. Over past years, many studies have acknowledged role parasitism for populations communities discovered regulatory functions vertebrate populations. Although birds a well-studied group vertebrat...
Birds contribute indirectly to human welfare as majority of them feed on insects and rodents some are efficient scavengers. Poultry forming is a leading profession which provides nutritive food products for consumption. However, these valuable resources can be infected with wide range blood parasites may affect their survival existence. In this study, the impact Haemoproteus, an intracellular s...
The current investigation was undertaken to study the gill histopathologies due infestation of helminth parasite, monogenetic trematode, Dactylogyrus vastator (Nybelin, 1924) in Indian major carp, Catla catla. There were only symptomatic samples diseased fishes comprised fingerlings and adults catla collected examined. Behaviour respond studied- partial suffocation, lethargic swimming clinical ...
The asexual reproduction cycle of Plasmodium falciparum, the parasite responsible for severe malaria, occurs within red blood cells. A merozoite invades a red cell in the circulation, develops and multiplies, and after about 48 hours ruptures the host cell, releasing 15-32 merozoites ready to invade new red blood cells. During this cycle, the parasite increases the host cell permeability so muc...
Anolis in the eastern Caribbean islands are hosts to three species of malaria parasite (Plasmodium). Although the parasites are widespread on the islands, little is known about their effects on infected lizards. Presented here is an inventory of some costs suffered by Anolis sabanus, the endemic solitary anole of Saba, Netherlands Antilles, when infected with Plasmodium azurophilum, Plasmodium ...
INTRODUCTION In order to detect Trypanosoma cruzi and determine the genetic profiles of the parasite during the chronic phase of Chagas disease (ChD), parasitological and molecular diagnostic methods were used to assess the blood of 91 patients without specific prior treatment. METHODS Blood samples were collected from 68 patients with cardiac ChD and 23 patients with an indeterminate form of...
UNLABELLED Schistosoma bovis is a blood-dwelling fluke of ruminants that lives for years inside the vasculature of their hosts. The parasite tegument covers the surface of the worms and plays a key role in the host-parasite relationship. The parasite molecules expressed at the tegument surface are potential targets for immune or drug intervention. The purpose of this work was the identification...
because of endemic parasitological infectious diseases in iran and contaminated vegetables, as one of the most important ways of contamination, carried out a parasitical study on 263 vegetable samples from 44 farms in the suburbs of tehran city, and also 166 vegetables samples from 20 green grocery markets in the same city. from 263 samples of farms 147 cases (65%) of contamination were recorde...
1. The malarial parasite is extracellular throughout its life cycle and migrates from red corpuscle to red corpuscle destroying each before it abandons it; in the brief intervals between, the parasite is free in the blood serum; it does not remain long free, but almost immediately attaches itself to another red corpuscle by means of delicate pseudopodia. 2. The compact form of the tertian paras...
Tsetse flies are the sole vectors of Trypanosoma brucei parasites that cause sleeping sickness. Our knowledge on the early interface between the infective metacyclic forms and the mammalian host skin is currently highly limited. Glossina morsitans flies infected with fluorescently tagged T. brucei parasites were used in this study to initiate natural infections in mice. Metacyclic trypanosomes ...
