Maternal antibodies protect chicks from infection with pathogens early in life and may impact pathogen dynamics due to the alteration of the proportion of susceptible individuals in a population. We investigated the transfer of maternal antibodies against avian influenza virus (AIV) in a key AIV host species, the mallard (Anas platyrhynchos). Combining observations in both the field and in mall...

Schistosomiasis, one of the most prevalent neglected parasitic diseases affecting humans and animals, is caused by the Platyhelminthes of the genus Schistosoma. Schistosomes are the only trematodes to have evolved sexual dimorphism and the constant pairing with a male is essential for the sexual maturation of the female. Pairing is required for the full development of the two major female organ...

AIM This study was conducted to determine the prevalence and burden of gastrointestinal (GIT) parasites of Djallonke sheep in Ayeduase, Kumasi from January 2015 to July 2015. MATERIALS AND METHODS The presence of nematodal eggs and coccidial oocysts in fecal samples were analyzed using the saturated sodium chloride floatation technique. Identification of eggs or oocysts was done on the basis ...

Clinical and subclinical intestinal parasitism is characterized by impaired production (Sykes & Coop, 1976; Steele, 1978) with poor growth rates in young animals and loss of body weight in older animals. Sheep also incur severe reductions in wool growth. A number of comprehensive reviews prepared over the last decade characterize and contrast the magnitude of such impairment across a range of i...

[b]Abstract [/b] Dogs serve as the vectors of serious zoonotic parasitic diseases. In the month of May 2012 - 2014, 339 dog faeces samples from seven public sites in Chełmno, a town in northern Poland, were collected and examined to determine the gastrointestinal parasite fauna of dogs. Each faecal sample was dissected with a needle, checked for tapeworm segments and examined for parasite eggs ...

In the Experimental Farm of the Universidade Federal de Lavras (EF-UFLA), state of Minas Gerais, Brazil, on their day of birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional Treatment (CT). In the S-ST, calves were treated after coproparasitological examinations according to criteria...

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...

In order to clarify the impacts of southern rice black-streaked dwarf virus (SRBSDV) infection on rice plants, rice planthoppers and natural enemies, differences in nutrients and volatile secondary metabolites between infected and healthy rice plants were examined. Furthermore, the impacts of virus-mediated changes in plants on the population growth of non-vector brown planthopper (BPH), Nilapa...

Parasites have the potential to severely reduce host reproductive success. However, the effects of endoparasites on reproductive success have not received the same amount of attention as the effects of parasites on host survival. We investigated the relationship between an avian endoparasite (gapeworm, Syngamus trachea) and both current and future reproductive success of female house sparrows (...

In Pakistan, parasitic infections are among major constraints to animal production. Gastro-intestinal (GI) parasites cause huge economic losses (direct or indirect) to livestock. In Pakistan, distribution and effect of GI parasitism in sheep is not very well studied. The present study was conducted to determine the prevalence of GI parasites in sheep population of Sialkot district, Punjab, Paki...
