A survey of parasite eggs and cysts in soil and dog feces collected in public places of 23 boroughs of Salvador, a city in the Northeast of Brazil, was performed. High degree of contamination by Toxocara sp eggs was observed in all boroughs studied; other parasites found included: Ascaris lumbricoides, hookworms, whipworms and protozoan cysts. Parks and public gardens were more contaminated tha...
Backgrounds Many wild-caught reptiles harbor some kind of parasites. Captivity with negative effect of poor sanitary and husbandry management may lead to clinical disease. The increasing trend in keeping non-native reptile species in the last decade emerged a need for the specification of reptile parasites and their hosts. Objectives The study aims to gain data on intestinal parasites of repti...
In coevolutionary arms races, like between cuckoos and their hosts, it is easy to understand why the host is under selection favouring anti-parasitism behaviour, such as egg rejection, which can lead to parasites evolving remarkable adaptations to 'trick' their host, such as mimetic eggs. But what about cases where the cuckoo egg is not mimetic and where the host does not act against it? Classi...
Hosts are expected to evolve resistance strategies that efficiently detect and resist exposure to virulent parasites and pathogens. When recognition is not error-proof, the acceptance threshold used by hosts to recognize parasites should be context dependent and become more restrictive with increasing predictability of parasitism. Here, we demonstrate that decisions of great reed warblers Acroc...
Parasite load can vary with seasonality, but this is rarely quantified. The garden skink (Lampropholis guichenoti) host to multiple species of endoparasite. To measure seasonal effects parasite transmission we established three captive groups wild-caught individuals in which 2 16 (12.5%) were initially infected nematodes. We collected faecal samples from each lizard, a sample at the beginning a...
Scabies is a contagious skin infestation caused by parasite. In its usual, common form scabies passed on through long-time close physical contact. Though rarely so, infestation, of the profuse and hyperkeratotic form, can also be shared clothes, bed or bathroom linen. causative agent female mite sarcoptes scabiei, called scab mites, small-size parasite, less than half millimeter in length, larg...
Echinococcus granulosus is widespread in Australian wildlife where its reproductive potential may be greater than in domestic animals. The parasite is zoonotic; humans may develop hydatid cysts following ingestion of eggs. Infected definitive hosts, dingoes, their hybrids and foxes may pose a public health risk but even heavy parasites loads are of no significance to the animals’ health. The pa...
In this study prevalence of parasites in 118 samples (62 foxes and 56 jackals) was investigated in Ilam province of Iran, in 2010-2013, situated in the western part of the national capital of Iran. The nematodes which were cleared in lactophenol, cestodes and acanthocephalans were stained using acetocarmine and haematoxylen, respectively for identification of the parasite species. Cryptosporidi...

The objective of this study was to use chlamydospores of the fungus Pochonia chlamydosporia (isolates VC1 and VC4) against Toxocara canis eggs in a 15-day in vitro assay. One thousand T. canis eggs were placed in Petri dishes containing 2% water agar medium with different concentrations of chlamydospores (1,000, 10,000 or 100,000) of each fungal isolate of P. chlamydosporia (treated groups) and...
