Introduction: To determine an indicator for Triclabendazole (TCBZ) efficacy, Alanine aminotransferase (ALT) activity in Fasciola hepatica (Iranian isolate) parasite in presence and absence of TCBZ was evaluated by an in vitro cultivation method. Also, ALT enzyme activity between none and parasitized-infected sheep liver tissues was assessed. Method: The sheep livers were collected and tra...
Models of host-parasite coevolution assume the presence of genetic variation for host resistance and parasite infectivity, as well as genotype-specific interactions. We used the freshwater crustacean Daphnia magna and its bacterial microparasite Pasteuria ramosa to study genetic variation for host susceptibility and parasite infectivity within each of two populations. We sought to answer the fo...
Understanding the processes that shape the genetic structure of parasite populations and the functional consequences of different parasite genotypes is critical for our ability to predict how an infection can spread through a host population and for the design of effective vaccines to combat infection and disease. Here, we examine how the genetic structure of parasite populations responds to ho...
introduction: the present study aimed to investigate the microbial quality of the produced vermicomposts and compare them with the existing standards. methods: this experimental study was conducted as a pilot-scale one, in the laboratory school. some perishable domestic waste were mixed in a reactor, including food waste, vegetables and fruits, cow manure and sludge of wastewater treatment plan...
abstract in order to study the effect of environmental factors (light, temperature, salinity and drought stress, acidity and burial depth) on germination and emergence of eastern dodder (cuscuta monogyna vahl), experiments were conducted at the research laboratory of faculty of agriculture, birjand university in 2009. results showed that seeds of this parasite weed had identical germination und...
objective(s):cutaneous leishmaniasis (cl) is a parasitic disease caused by various species of the flagellated protozoan, leishmania. regardless of the numerous studies, there are still serious challenges in the treatment of cl. this study aimed at evaluating the influence of a low dose ultraviolet b (uvb) radiation along with silver nanoparticles (agnps) on a mouse model of cl induced by leishm...
