Glodavci su važni štetnici uskladištenih poljoprivrednih proizvoda. Uz zadovoljenje osnovnih prehrambenih potreba, štetne vrste u skladištima nalaze povoljne uvjete za razvoj i razmnožavanje te zaštitu od prirodnih neprijatelja. Najštetnije vrste glodavaca u skladištima Republike Hrvatske jesu štakori vrsta Rattus norvegicus i Rattus rattus te domaći miš Mus musculus. Osim što se hrane uskladištenim proizvodima, rasipaju ih, onečišćuju urinom, izmetom, dlakom i slinom, navedene vrste rezervoari su zoonozama koje utječu na zdravlje ljudi, te domaćih i divljih životinja. U Republici Hrvatskoj u populacijama sitnih glodavaca dokazani su uzročnici Lajmske borelioza, trihineloze, leptospiroze, Q groznice i hemoragijske vrućice s bubrežnim sindromom. Utvrđene su i višestruke infekcije glodavaca uzročnicima zoonoza. Redovito praćenje brojnosti glodavaca važno je u svrhu pravovremenog suzbijanja te smanjenja materijalnih gubitaka, ali i u svrhu sprječavanja pojave epidemija zoonoza. Uz preventivne mjere koje podrazumijevaju održavanje higijene prostora te održavanje infrastrukture, čime sprječavamo privlačenje i nastanjivanje glodavaca u skladištima, provodi se i kontinuirana deratizacija koja uključuje primjenu mehaničkih, fizikalnih i kemijskih mjera zaštite.

The article considers the issues of carriage by small mammals of dangerous zoonotic diseases: leptospirosis, tularemia, hantaviruses. Data on the detection of antigens to pathogens in the districts of the Kaluga region are presented. As you know, small mammals are the main link in maintaining zoonotic natural focal diseases. The larval phases of ixodic ticks, mosquitoes and other parasitic arthropods prefer to feed on the blood of mouse rodents, which contributes to the spread of vector-borne infections and infestations. The following species of mouse rodents are found in the Kaluga Region: small forest mouse (Apodemus uralensis), gray vole, red vole (Myodes glareolus), field mouse (Apodemus agrarius), gray rat (Rattus norvegicus), and house mouse (Mus musculus). In natural biotopes, field species prevail in number: field mouse, gray vole, red vole. In the Kaluga region, antigens for tularemia, hantaviruses, and leptospirosis were found in small mammals in 4.9–9.4% of the studied animals on average per year. Of particular concern are the city of Kaluga, Borovsky, Babyninsky, Yukhnovsky, Ulyanovsk, Medynsky, Maloyaroslavetsky, Meshchovsky, Peremyshlsky, Kozelsky, Dzerzhinsky and Ulyanovsk districts. The data obtained indicate the stationarity of these diseases in the territory of the Kaluga region.

Neste trabalho, está relatada a metodologia sobre a criação e manejo de uma cepa de Calomys callosus Rengger, 1830 (Rodentia-Cricetidae) chamada Canabrava, em condicoes de cativeiro. Os resultados mostram que este roedor pode se constituir em mais uma opção como animal de laboratório. No cativeiro C. callosus apresenta varias vantagens tais como: fácil manuseio, produtividade alta, reprodução durante todo ano, aparente resistência as infecções comuns a ratos (Rattus norvegicus), camundongos (Mus musculus) e cobaias (Cavia aperea). Por ser roedor de pequeno porte, a criação de C. callosus não requer grandes espaços e custos altos.

ABSTRACT Betaretroviruses exist in endogenous and exogenous forms in hosts that are widely distributed and evolutionarily distantly related. Here we report the discovery and characterization of several previously unknown betaretrovirus groups in the genomes of Mus musculus and Rattus norvegicus. Each group contains both mouse and rat elements, and several of the groups are more closely related to previously known betaretroviruses from nonmurine hosts. Some of the groups also include members from hosts which were not previously known to harbor betaretroviruses, such as the gray mouse lemur (Microcebus murinus) and Seba's short-tailed bat (Carollia perspicillata). Some of the mouse and rat elements possess intact open reading frames for gag, pro, pol, and/or env genes and display characteristics of having retrotransposed recently. We propose a model whereby betaretroviruses have been evolving within the genomes of murid rodents for at least the last 20 million years and, subsequent to (or concomitant with) the global spread of their murid hosts, have occasionally been transmitted to other species.

1. A description of the morphology and life history (excluding metacystic development) of Entamoeba muris is given.2. The descriptions of species of amoebae found in rats (Rattus norvegicus and R. rattus) and mice (Mus musculus) by previous authors are critically discussed, and it is concluded that one species, Entamoeba muris, is present.3 Experiments on cross-infection of rats and mice with E. muris are described, together with observations on the course of these infections.4. The transference of an amoeba morphologically similar to E. muris from Cricetus auratus to rats and mice is described.5. An account is given of unsuccessful attempts to establish an infection of Entamoeba coli in rats and mice.6. Observations on the incidence and hostrestriction of E. muris are discussed.7. The affinities of E. coli and E. muris are discussed and it is concluded that, although E. muris resembles E. coli morphologically, it differs from E. coli on physiological grounds.

Background: Rodents are one of the most important hosts for some zoonotic diseases and also act as a reservoir of some ectoparasites and endoparasites. They cause damage to the farms and inflict public health. The aim of this study was to investigate the faunal composition of rodent in North Khorasan Province, Northeast of Iran. Methods: The sampling was carried out between 2011 to 2013. The specimens were collected using different methods including rodent death and live traps, digging of their burrow, and hand net from 75 different sample sites. Results: The total number of 396 specimens belonging to 22 species and six families were identified. The results illustrated the high numbers and densities of Meriones persicus (17.68%), Meriones libycus (15.15%), Nesokia indica (7.32%) and Rhombomys opimus (6.82%), as the most important reservoirs for different zoonotic diseases. Moreover, significant number of other rodent species including Mus musculus (15.66%), Apodemus witherbyi (13.89%), A. hyrcanicus (0.25%), Rattus norvegicus (1.01%), Meriones crassus (0.25%), Gerbillus nanus (0.51%), Microtus paradoxus (2.27%), M. transcaspicus (0.76%), Ellobius fuscocapillus (0.25%), Cricetulus migratorius (4.29%), Calomyscus elburzensis (4.29%), C. mystax (1.26%), Spermophilus fulvus (0.25%), Dryomys nitedula (3.54%), Allactaga elater (3.54%), Jaculus blanfordi (0.25%), Meriones zarudnyi (0.25%), M. meridianus (0.51%), and Hystrix indica as hosts for parasites and zoonotic diseases were identified. Conclusion: The high biodiversity including at least 22 species and six families of rodents were found in North Khorasan Province, some of them were medically important species.
