The present work provides an updated checklist of helminth species infecting invasive murid rodents (Mus musculus, Rattus norvegicus, R. rattus, and Rattus sp.) in Mexico, including 35 helminth taxa (3 trematodes, 7 cestodes, 2 acanthocephalans, and 23 nematodes).  The helminthological records were compiled from 18 studies conducted in seven Mexican states up to May 2020.  Information on habitats, life stages, geographical locations, hosts, helminthological collections, prevalences, and bibliographic references are included, when available.  Finally, a new locality record of the nematode Hassalstrongylus musculi in Yucatan is provided.

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.

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.

AbstractThe helminth communities of wild murid rodents were investigated in Luang Prabang and Champasak province, Lao PDR. Thirteen species of rodents (404 individuals) were infected by 19 species of parasites (2 trematode, 3 cestode, 14 nematode species). Four of the recorded helminth species (Echinostoma malayanum,Raillietinasp.,Hymenolepis diminutaandH. nana)are known to cause potential zoonotic helminthiases of medical importance in the South-East Asian region. Individual helminth infection was significantly higher in the wet season. Habitat significantly influenced individual helminth species richness and individual helminth abudance, with a decrease of individual helminth species richness and individual helminth abundance from forest habitat to agricultural and human settlement habitats. The reduction of helminth diversity and abundance is discussed in relation to the ongoing increase of human influence on habitats in Lao PDR.

Abstract Currently, descriptive information on the host range and geographic distribution of helminth parasites associated with naturally occurring rodents in South and southern Africa is scant. Therefore, we embarked on a countrywide study to: (1) identify gastrointestinal helminths and their host range, and (2) provide baseline data on the geographic distribution of helminths across the country. Altogether, 55 helminth taxa were recovered from at least 13 rodent species (n = 1030) at 26 localities across South Africa. The helminth taxa represented 25 genera (15 nematodes, nine cestodes and one acanthocephalan). Monoxenous nematodes were the most abundant and prevalent group, while the occurrence of heteroxenous nematodes and cestodes was generally lower. The study recorded several novel helminth–host associations. Single-host-species infections were common, although multiple-host-species infections by helminth species were also recorded. Monoxenous nematodes and some cestodes were recovered countrywide, whereas heteroxenous nematodes were restricted to the eastern regions of South Africa. The study highlights the as yet unexplored diversity of helminth species associated with naturally occurring rodent species and provides initial data on their geographical distribution in South Africa.

Unpublished Information

Based on published records and unpublished information retrieved from the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC), a checklist of the helminth parasites of cetaceans from Brazil was generated. A total of 215 records of 18 species of helminths were associated with 22 species of cetaceans in Brazil. Six species determined only to genus were also included. The majority of these helminth species are nematodes (33.3%) and trematodes (33.3%), which total 66.6% of the helminth fauna of cetaceans from Brazil. The Acanthocephala represents 22.2% of species, and the Cestoda 11.1%.

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.
