linguatula serrata is one of the important zoonotic parasites. carnivores serve as definitive host. the larvae existed in mesenteric lymph nodes (mlns), liver, lungs, etc of intermediate herbivores. the definitive host becomes infected by ingesting viscera containing the infective nymphal stage. humans may be infected with linguatula either by ingestion of nymphs resulting in a condition called...

rodent ectoparasites seems have a main role in transmission of some zoonotic pathogens from commensal rats to human and pets such as leishmaniasis, plague, cchf, etc. so rodents as the main reservoirs, are potential health dangers in human communities. the aim of this study was to determine the prevalence and frequency of identified ectoparasites in north of tehran . rodents were captured with ...

The benzoylurea chitin synthesis inhibitor diflubenzuron was evaluated as a rodent feed-through for the control of immature stages of Phlebotomus papatasi Scopoli (Diptera: Psychodidae). The development and survival of second instars of P. papatasi larvae that were fed feces from Syrian hamsters, Mesocricetus auratus, that had been fed a diet containing 0, 8.97, 89.7, or 897 ppm diflubenzuron w...

Background: Humans, rodents and sandflies have role in transmitted cycle of cutaneous leishmaniasis. To control the disease, promoting the environment, killing the rodent and poisoning the vectors are recommended, individually all over the world. Since, there is no effective vaccine against this disease, the integration of methods is considerable. Objective: To evaluate the efficacy of integrat...

A field study was conducted in Lewis and Clark County, Montana, during the summer of 1986 to determine the fate of Columbian ground squirrel (Spermophilus columbianus) carcasses in the environment. Ground squirrel carcasses were marked with radio transmitters and placed in situations and locations similar to those found in actual rodent control operations. Carcasses were monitored until their f...

Calorie restriction (CR) has been known for more than 70 years to extend life span and delay disease in rodent models. Metformin administration in rodent disease models has been shown to delay cancer incidence and progression, reduce cardiovascular disease and extend life span. To more directly test the potential of metformin supplementation (300 mg/kg/day) as a CR mimetic, life-span studies we...
