Insight into the dynamics of parasite-host relationships of higher vertebrates requires an understanding of two important features: the nature of transmission and the development of acquired immunity in the host. A dominant hypothesis proposes that acquired immunity develops with the cumulative exposure to infection, and consequently predicts a negative relationship between peak intensity of in...

This paper shows the results of outpatient treatment 10 children suffering from acute rotavirus diarrhea with homeopathic preparation Tormentilla erecta. The intensity infection symptoms was decreased as well full course infection, which completed in 3 days.

In this work were investigated the relationship between Hookworm/Schistosoma mansoni infections and allergy related risk factors in two endemic areas with distinct prevalence of infections and co-infection. The intensity of infections, eosinophilia, allergy risk factors, infections status and anti-Der p1 IgE levels before and 2 years (population 1) and 3 years (population 2) after anthelmintic ...

This study quantifies the infection prevalence and intensity of the European, commensal, host-specific ciliate Conchophthirus acuminatus (Scuticociliatida: Conchophthiridae) in five zebra mussel populations within the Republic of Belarus. Laboratory and field experiments were also conducted to assess variables affecting infection. C. acuminatus was found in zebra mussels in all five waterbodies...

A cross-sectional study in Itagua, Paraguay tested 192 people for the presence, intensity and species of hookworm infection. Fifty-nine percent of these individuals were found to be infected. Intensity of infection was determined on 92% of infected individuals by quantitative egg counts. The high intensity hookworm infections, which cause the greatest morbidity, were clustered between the ages ...

BACKGROUND It is thought that improving water, sanitation, and hygiene (WASH) might reduce the transmission of schistosomes and soil-transmitted helminths, owing to their life cycles. However, few large-scale studies have yet assessed the real extent of associations between WASH and these parasites. METHODOLOGY/PRINCIPAL FINDINGS In the 2013-2014 Ethiopian national mapping of infections with ...

The full course of new parasite introductions in wild animals is difficult to accurately trace. We documented and analysed the invasive blood-sucking nematode Ashworthius sidemi (Trichostrongylidae) introduction and spread in European bison (Bison bonasus) from the initial phase of its progression. In the Polish part of the Białowieża Primeval Forest (BPF) the parasite was first found in 2000. ...

BACKGROUND Accurate quantitative assessment of infection with soil transmitted helminths and protozoa is key to the interpretation of epidemiologic studies of these parasites, as well as for monitoring large scale treatment efficacy and effectiveness studies. As morbidity and transmission of helminth infections are directly related to both the prevalence and intensity of infection, there is par...

BACKGROUND I investigated the effects of steam sterilization on light intensity of reusable fiberoptic laryngoscope blades. METHODS Six new reusable fiberoptic Macintosh laryngoscope blades were steam sterilized. The light intensity was measured, the tip of the blades was photographed, and the light intensity of six new plastic disposable Macintosh laryngoscope blades was also measured. RES...

Mosquito feeding assays are important in evaluations of malaria transmission-reducing interventions. The proportion of mosquitoes with midgut oocysts is commonly used as an outcome measure, but in natural low intensity infections the effect of oocyst non-rupture on mosquito infectivity is unclear. By identifying ruptured as well as intact oocysts, we show that in low intensity P. falciparum inf...
