the prevalence of eimeria spp. infection and the intensity of fecal oocysts were determined in 250 sheep in malayer suburb of iran using flotation and sporulation techniques. the overall prevalence was 23.23% in which the young male sheep had the highest prevalence (37.61%) with the highest intensity (63.58%). there were no significant difference in the prevalence between male (27.9%) and femal...

in this research, the effect of crops such as corn, wheat, sugar beet and clover as previous crop on incidence of leaf and crown wart disease of sugar beet was studied. in the first year, corn, wheat, clover and sugar beet were planted as previous crop in a randomized complete block design with four replications. the amounts of turnover of nitrogen to the soil due to crop residue and their effe...

This investigation was carried out to determine the prevalence of Eimeria infections and the diversity of Eimeria species in camels of Tabriz region. The prevalence of Eimeria spp. infection and the intensity of faecal oocysts were determined in 164 camels using floatation and sporulation techniques. Faeces of 34 camels (20.73%) were infected with four Eimeria species including E. bactriani (52...

BACKGROUND Although parasitism has been acknowledged as an important selective force in the evolution of host life histories, studies of fitness effects of parasites in wild populations have yielded mixed results. One reason for this may be that most studies only test for a linear relationship between infection intensity and host fitness. If resistance to parasites is costly, however, fitness m...

While avian chronic haemoparasite infections induce reproductive costs, infection has not previously been shown to affect survival. Here, we experimentally reduced, through medication, the intensity of infection by Haemoproteus parasites in wild-breeding female blue tits Cyanistes caeruleus. However, this treatment did not reduce the intensity of infection in males or the intensity of infection...

The prevalence and intensity of soil-transmitted helminths in five rural villages in northern peninsular were investigated. Generally the prevalence and intensity of infection were low in the 0-10- and above 50-year-old age groups when compared with other age groups. The prevalence and intensity of infection in the five villages were quite similar, because of similar socio-economic status. The ...

There are remarkably few contemporary, population-based studies of intestinal nematode infection for sub-Saharan Africa. This paper presents a comprehensive epidemiological analysis of hookworm infection intensity in a rural Ugandan community. Demographic, kinship, socioeconomic and environmental data were collected for 1,803 individuals aged six months to 85 years in 341 households in a cross-...

BACKGROUND In schistosomiasis control programmes using mass chemotherapy, epidemiological and morbidity aspects of the disease need to be studied so as to monitor the impact of treatment, and make recommendations accordingly. These aspects were examined in the community of Musoli village along Lake Victoria in Mayuge district, highly endemic for Schistosoma mansoni infection. METHODOLOGY AND ...

Host resistance against parasites depends on three aspects: the ability to prevent, control and clear infections. In vertebrates the immune system consists of innate and adaptive immunity. Innate immunity is particularly important for preventing infection and eradicating established infections at an early stage while adaptive immunity is slow, but powerful, and essential for controlling infecti...
