Field Rodents

SummaryShort laboratory feeding tests were carried out with the anticoagulants warfarin, difenacoum, and brodifacoum on a number of European rodent species: Clethrionomys glareolus, Microtus agrestis, M. arvalis, Apodemus flavicollis, A. sylvaticus, Mus musculus, Rattus rattus and R. norvegicus. It was found that the toxicity to all species was highest with brodifacoum and lowest with warfarin, and that only 0·005% brodifacoum would give a complete mortality in most species after one day's feeding. The potential of this compound for the control of microtine field rodents is suggested.

Small mammal communities were studies in tree plantations in 2007-2011. The monitoring was conducted at 18 plots in the Jeseníky Mts. and 18 plots in the Beskydy Mts. using snap traps placed in lines. A total of 588 individuals of 10 species were captured in the Jeseníky Mts. and 577 individuals of 13 species in the Beskydy Mts. The Beskydy lot encompassed 5 insectivorous species and 8 rodent species, 4 of them eudominant (Apodemus flavicollis, D=43.33 %; Clethrionomys glareolus, D=21.49 %; Microtus agrestis, D=18.54 %; and Sorex araneus, D=10.05 %), one subdominant (Apodemus sylvaticus, D=2.77 %), two recedent (Microtus arvalis, D=1.39 %; Muscardinus avellanarius, D=1.04 %) and six sub-recedent (Microtus subterraneus and Sorex minutus: D=0.35 % and Apodemus agrarius, Neomys anomalus, Sorex alpinus and Talpa europea: D=0.17 %). The occurrence of 3 insectivorous species and 7 rodent species was confirmed in the Jeseníky Mts. Four species were eudominant (A. flavicollis, D=30.1 %; Clethrionomys glareolus, D=27.04 %; Microtus agrestis, D=24.49 %; and S. araneus, D=12.59 %), one species subdominant (Microtus arvalis; D=3.57 %), five species sub-recedent (A. sylvaticus, D=0.68 %; Crocidura suaveolens and Microtus subterraneus: D=0.34 %, Muscardinus avellanarius and S. minutus: D=0.17 %). According to the employed indexes, the total biodiversity was slightly higher in the Jeseníky Mts. (H=1.53; d=0.76; E=0.66) than in the Beskydy Mts. (H=1.52; d=0.72; E=0.59). The structure of the small mammal communities was strongly affected by the herb layer composition.

Public Health Importance

Rodents carry many ectoparasites, such as ticks, lice, fleas, and mites, which have potential public health importance. Middle Eastern countries are hotspots for many emerging and re-emerging infectious diseases, such as plague, leishmaniasis, Crimean Congo hemorrhagic fever, and Q fever, due to their ecological, socioeconomic, and political diversity. Rodent ectoparasites can act as vectors for many of these pathogens. Knowledge of rodent ectoparasites is of prime importance in controlling rodent ectoparasite-borne zoonotic diseases in this region. The current systematic review and meta-analysis performs a comprehensive synthesis of the available knowledge, providing an evidence-based overview of the ectoparasites detected on rodents in Middle Eastern countries. Following a systematic search in Pubmed, Scopus, and Web of Science, a total of 113 published articles on rodent ectoparasites were studied and analyzed. A total of 87 rodent species were documented, from which Mus musculus, Rattus norvegicus, and Rattus rattus were found to be the most common. Fleas were the most reported ectoparasites (87 articles), followed by mites (53), ticks (44), and lice (25). Xenopsylla cheopis, Polyplax spinulosa, Ornithonyssus bacoti, and Hyalomma rhipicephaloides were the most commonly described fleas, lice, mites, and ticks, respectively. Based on the reviewed articles, the median flea, louse, mite, and tick indices were highest in Israel (4.15), Egypt (1.39), Egypt (1.27), and Saudi Arabia (1.17), respectively. Quantitative meta-analysis, using a random-effects model, determined the overall pooled flea prevalence in the Middle East as 40% (95% CI: 25–55, I2 = 100%, p < 0.00001), ranging between 13% (95% CI: 0–30, I2 = 95%, p < 0.00001) in Iran and 59% (95% CI: 42–77, I2 = 75%, p < 0.00001) in Israel. The overall pooled louse prevalence was found to be 30% (95% CI: 13–47, I2 = 100%, p < 0.00001), ranging between 25% in Iran (95% CI: 1–50, I2 = 99%) and 38% in Egypt (95% CI: 7–68, I2 = 100%). In the case of mites, the pooled prevalence in this region was 33% (95% CI: 11–55, I2 = 100%, p < 0.00001), where the country-specific prevalence estimates were 30% in Iran (95% CI: 4–56, I2 = 99%) and 32% in Egypt (95% CI: 0–76, I2 = 100%). For ticks, the overall prevalence was found to be 25% (95% CI: 2–47, I2 = 100%, p < 0.00001), ranging from 16% in Iran (95% CI: 7–25, I2 = 74%) to 42% in Egypt (95% CI: 1–85, I2 = 100%). The control of rodent ectoparasites should be considered to reduce their adverse effects. Using the One Health strategy, rodent control, and precisely control of the most common rodent species, i.e., Mus musculus, Rattus norvegicus, and Rattus rattus, should be considered to control the rodent-borne ectoparasites in this region.

<p>La leptospirosis es una zoonosis causada por bacterias del género Leptospira sp., las cuales regularmente provocan brotes de la enfermedad en Argentina, donde el conocimiento de su epidemiología es incompleto. Los roedores (ratas y ratones sinantrópicos y silvestres) son los principales reservorios de leptospirosis en nuestro medio. El objetivo del estudio fue investigar la presencia de Leptospira sp. en roedores de la Ciudad de Corrientes, Argentina, así como la especie, sexo y edad de los ejemplares positivos a leptospirosis. Fueron capturados 101 especimenes, cuyo tejido renal fue utilizado para demostrar la presencia de Leptospira sp. mediante microscopio de campo oscuro a partir de cultivos de 15 días hasta un máximo de 6 meses. La tasa de positividad detectada fue de 58,4%, con una alta proporción de animales machos de la especie Rattus rattus. Solamente pudo capturarse un ejemplar de Mus musculus, que resultó infectado. Se concluye que la alta prevalencia de leptospirosis en roedores del área en estudio constituye un alarmante factor de riesgo de infección en animales domésticos y seres humanos.</p>

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.

We evaluated the role of communities of small mammals from three distinct areas in a region of Cerrado mixed with Atlantic Forest remains for maintenance of tick fauna. Thirty-nine marsupials (Gracilinanus agilis, n = 34; Marmosa paraguaiana, n = 4; Didelphis albiventris, n = 1) and 33 rodents (Oecomys cleberi, n = 10; Nectomys squamipes, n = 4; Calomys tener, n = 4; Hylaeamys megacephalus, n = 4; Akodon sp., n = 3; Rattus rattus, n = 3; Cerradomys subflavus, n = 2; Mus musculus, n = 2; Rhipidomys macrurus, n = 1) were captured. Solely G. agilis and the four rodent species (N. squamipes, R. macrurus, C. subflavus and Akodon sp.) were infested. Four tick species were collected (Amblyomma dubitatum, Amblyomma sculptum, Ixodes loricatus and Ornithodoros mimon). A. dubitatum was the most abundant tick species on hosts. Capture success was higher in the dry season, but the infestation was similar in both seasons. Forested habitats, particularly riparian forests, resulted in higher number of hosts and ticks collected (from hosts and from vegetation), compared to pastures and anthropized sites. The association between C. subflavus and I. loricatus and between A. dubitatum and N. squamipes observed here is the first recorded in Cerrado biome. Areas with more patches of forest, including the Atlantic Forest fragments, tend to present a richest community of small mammals and associated ticks.
