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.

Cercariae of Plagiorchis peterborensis sp. n. were obtained from Lymnaea stagnalis appressa, and the life cycle was completed using Aedes aegypti larvae and laboratory mice as experimental hosts. Description of the adult is based upon whole mounts and serial sections of 14-day-old worms. P. peterborensis resembles most closely P. muris, but differs in stylet shape, adult dimensions, and egg size.

Cestodes found to represent previously undescribed members of the genus Hymenolepis s.str. (Yamaguti 1959) were recovered from pocket gophers, Geomys bursarius (Shaw), in northeastern Colorado. Hymenolepis weldensis n.sp. and Hymenolepis geomydis n.sp., not occurring together in any individual host, were found in 3 and 8%, respectively, of pocket gophers examined for helminths. The life cycle of H. weldensis was completed in the laboratory using beetles, Tenebrio molitor (L.), as intermediate hosts, and pocket gophers of three genera (Geomys, Thomomys, and Pappogeomys) as definitive hosts. Development of H. weldensis did not occur in laboratory rats, Rattus norvegicus (Berkenhout). Morphologic relationships four species of Hymenolepis (H. diminuta, H. tualatinensis, H. weldensis, and H. geomydis) were analyzed using multiple discriminant function analysis, which clearly allocated individual cestodes to the respective groups and discriminated species.
