Context For the past 50 years, rodent eradications have been conducted worldwide to reverse devastating impacts of introduced rodents on island species. However, few studies quantitatively measured effects native Aims This study investigated a eradication Lord Howe Island two birds. Methods To mitigate risk currawongs being poisoned during baiting operations, 30–40% population were taken into c...

Cyclooxygenase-2 (COX-2; Ptgs2) acts as a tumor promoter in rodent models for colorectal cancer, but its precise role in carcinogenesis remains unclear. We evaluated the contribution of host-derived COX-1 and COX-2 in tumor growth using both genetic and pharmacological approaches. Lewis lung carcinoma (LLC) cells grow rapidly as solid tumors when implanted in C57BL/6 mice. We found that tumor g...

We determined the prevalence of infection with lymphocytic choriomeningitis virus (LCMV) among small mammals in northern Italy and analyzed long-term dynamics of LCMV in a rodent population in the province of Trento. LCMV is circulating among the most widespread and common wild rodent species in this area (Apodemus flavicollis, Myodes glareolus, and Microtus arvalis); overall prevalence is 6.8%...

Erythrocyte invasion by malaria parasites is a complex multistep process involving parasite and erythrocyte receptors. It is a critical stage in the parasite life cycle and, therefore, a logical step in which to intervene to prevent or ameliorate disease. Rodent models of malaria, commonly Plasmodium yoelii, are frequently used for studies of malaria pathogenesis. Little is known, however, abou...

background: the aim of this study was to determine intestinal and liver helminth infections in rattus rodents in tehran iran. methods: overall, 306 traps were put in 39 different regions in tehran from 2009 to 2010. rodents, including r. rattus and r. norvegicus were caught by live-traps.they become unconscious and the spinal cords were cut, afterwards the body was dissected and the stomach, sm...

• PfDHPS-A437G is known as one of sulfadoxine-resistant mutations in P. falciparum . PbDHPS-A394G berghei corresponds to PfDHPS-A437G. We generated a transgenic parasite and investigated the developments. grew mice produced oocysts with similar efficiency wild-type. The mutation may not impose fitness costs on during examined stages. Genetic changes conferring drug resistance are generally beli...
