SUMMARYThe properties of 5-p-chlorophenyl silatrane as a rodenticide against Rattus norvegicus and Mus musculus were investigated in the laboratory. The high oral toxicity of the compound was confirmed. When the compound was given to laboratory rats and mice by stomach tube at lethal dosages, signs of poisoning were observed within a minute. When caged wild rats and mice were given a choice between plain and poisoned baits the optimum rodenticidal concentration in the bait was about 0.5% for both species, producing 50% mortality in wild rats and 95% mortality in wild mice. The results are discussed in relation to safety in use and the probable effectiveness of the compound as a rodenticide in field conditions.

Approximate Lethal Dose

The potential hazard of 1080 baiting for predators to 14 species of non-target mammals in the pastoral areas of Western Australia and a further six from Western Australia's Fitzgerald River National Park, was assessed by comparing projected doses of 1080 (based on consumption of non-toxic bait by captive animals in the absence of alternative food) with the approximate lethal dose of 1080 for each species. These figures suggested that individuals from 12 species were potentially at risk from crackle baits, while only individuals from Dasyurus hallucatus, Ningaui spp., Sminthopsis crassicaudata, Planigale maculata, one population of Leggadina forresti and one population of Sminthopsis ooldea were potentially endangered by meat baits. Tests using the native mammals Zyzomys argurus and Pseudomys hermannsbergensis and laboratory mice (Mus musculus) and laboratory rats (Rattus norvegicus) showed that individuals of all species reduced their consumption of toxic bait relative to non-toxic bait, although this did not prevent three of five rats and one of three P. hermannsbergensis from being killed.

Subcutaneous Inoculation

The susceptibility of laboratory rats (Rattus norvegicus) to experimental inoculation with tachyzoites of Neospora caninum was examined. Groups of female rats were intramuscularly injected with 0, 2, or 4 mg of methylprednisolone acetate (MPA) 7 days prior to, and on the day of, subcutaneous inoculation with 0 or 1.5 × 105 tachyzoites. Clinical signs of disease or deaths did not occur in rats given nothing or only N. caninum tachyzoites. Rats given only 4 mg MPA failed to grow as well as rats given nothing or only N. caninum tachyzoites but were otherwise healthy. All of 20 rats given 4 mg MPA and tachyzoites died of hepatitis and pneumonia within 12 days postinoculation. Hepatic necrosis was the most striking lesion seen in these rats, and other milder lesions consisted of pneumonia, encephalitis, and myositis. The response of rats given 2 mg MPA and tachyzoites was less severe. Three of 20 rats died with encephalitis, myositis, hepatitis, and pancreatitis. Mild lesions, but no N. caninum tachyzoites, were seen in 3 of 14 rats inoculated only with tachyzoites. Rats given the 4 mg MPA treatment and inoculated with N. caninum tachyzoites appear to be suitable subjects for examining acute neosporosis and could be used in studies designed to examine treatment of acute disease.

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.

Hymenolepis nana and Hymenolepis diminuta are globally widespread zoonotic cestodes and rats act as main reservoir host of these cestodes. Wild brown rats (Rattus norvegicus) are the most common rats usually live in human’s dwellings, especially in areas of low socioeconomic status and low levels of hygiene practices. Since there is scarcity of information of the hymenolepiasis in rats in Bangladesh, therefore the aim of this study was to determine the incidence of H. nana and H. diminuta in wild and laboratory rats. A total of 60 rats were collected from the residential areas of rural villages of Mymensingh sadar and the Bangladesh Agricultural University campus and 10 were from the laboratory of the Department of Parasitology, BAU, Mymensingh. The rats were killed by cardiac puncture and tapeworms were collected and subsequently were subjected for morphological study under the stereomicroscope. Two species of cestodes, namely H. nana and H. diminuta were detected showing the overall prevalence of 23.3 % and 35 % respectively. The high prevalence of H. nana (30%) was determined in rats captured from the rural village areas whereas H. diminuta was found more prevalent (60%) in the laboratory rats. The result of the current study suggests that H. nana infection in rural village areas may act as a risk factor for the zoonotic transmission of hymenolepiasis to human in Bangladesh. Res.
