the incorporation of several anti-rodent masterbatches into polyethylene (pe) granules used for gas pipes and the effects of the masterbatches on the physical properties of the pipes were studied. four commercial anti-rodent masterbatches from different international companies including, clariant, alchemix, polyone, and newgen were used in this research. each of the masterbatch was primarily dr...

background: in this paper, paleoparasitological findings from rodent excrements ob-tained from chehrabad salt mine archeological site located in northwest of iran are demonstrated and discussed. methods : chehrabad salt mine archeological site located in northwest of iran, dated to the achaemenid (mid 1st mill. bce) and to sassanid (3rd cent. - 7th cent. ce) period, is a unique study area to in...

background: rodents play an important role as reservoir of some pathogens, and the host of some ectoparasites as well. these ectoparasites can transmit rodents’ pathogens to human or animals. the aim of this study was to assess the distribution and infestation load of ectoparasites on rodents in meshkin-shahr district, northwestern iran . method: rodents were captured using baited live traps in...

b a ckground: zoonotic cutaneous leishmaniasis (zcl) is endemic in many parts of iran. recently its incidence isconsiderable in different parts of jahrom district, in fars province, southern iran. the aims of our study were to in- vestigate the prevalence of leishmania infection, and identify and characterize the   leishmania species present, among the rodents by molecular methods in a new ende...

Seventy four SNP genotypes and 54 E. coli genomes from kangaroo, Tasmanian devil, reptile, cattle, dog, horse, duck, bird, fish, rodent, human and environmental water sources were screened for the presence of the CRISPR 2.1 loci flanked by cas2 and iap genes. CRISPR 2.1 regions were found in 49% of the strains analysed. The majority of human E. coli isolates lacked the CRISPR 2.1 locus. We desc...

The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABA)ergic dysfunction in dorsomedial and posterior hypothalamic nuclei is implicated in the origin of panic-like defensive behavior, as well as in pain modulation. The present study was conducted to test the difference between these two hypothal...

leishmania infantum, an etiologic agent of zoonotic visceral leishmaniasis (vl), is spreading in iran. dogs are the main reservoirs but l.infantum has been detected in jackals, foxes and wild rodents too. despite high number of rodents in the world, the exact role of them in epidemiology of vl is not clear. in recent years the number of sporadic cases of dogs and humans vl has been increased in...
