Black rats (Rattus rattus) and house mice (Mus musculus) from Lord Howe Island were live-trapped, housed in the laboratory and tested for resistance to the anticoagulant poison warfarin. All rats fed warfarin (0.025% w/w) in their diet died within 4–12 days whereas no rats in the untreated group died. Mice fed warfarin at the same concentration over 21 days all survived. Black rats on Lord Howe Island remain susceptible to warfarin, but house mice appear resistant.

A three-year programme to eradicate Feral Cats Felis catus from the island of Baltra in the Galapagos archipelago achieved good results by initially poisoning with sodium monofluoroacetate (compound 1080) then trapping or shooting the remaining cats. The poisoning campaign removed 90% of the cats, its success being attributable to pre-baiting with unpolsoned baits to accustom cats to eating baits and placing enough baits to ensure that all cats encountered several baits within their home range. This, together with the use of metaclopromide (Pileran) as an anti-emetic, overcame a problem associated with poor retention of 1080 in thawed fish baits that limited the dose available to 1 mg 1080/bait, a quality insufficient to kill large cats. Removal of the remaining cats was delayed by a weather-induced irruption of Black Rats Rattus rattus and House Mice Mus musculus that enabled recruitment of kittens in 2002, but made cats more susceptible to trapping and shooting in 2003 when rodent populations collapsed. Since July 2003 no sign of a cat has been detected on Baltra despite extensive searching and monitoring throughout 2004. As cat abundance has decreased there have been more locally-bred Juvenile iguanas (Conolophus subcristatus) seen during annual censuses. However, such recruitment may reflect the increasing maturity and higher fecundity of iguanas repatriated from 1991 onwards rather than being a direct result of reduced cat predation alone. More time is necessary to determine the benefits of reduced cat predation on the Iguana population.

Seven taxa of raptorial birds were experimentally fed a controlled sample of 50 house mice (Mus musculus). Bones recovered from the pellets were examined for interspecies variability in preservation to assess the potential contribution of specific raptors to patterning in fossil assemblages. Quantitative analyses demonstrate that patterns in bone fragmentation may assist in the identification of particular raptor species as depositional agents in small mammal assemblages.

The house mouse, Mus musculus, was established in the early 1900s as one of the first genetic model organisms owing to its short generation time, comparatively large litters, ease of husbandry, and visible phenotypic variants. For these reasons and because they are mammals, house mice are well suited to serve as models for human phenotypes and disease. House mice in the wild consist of at least three distinct subspecies and harbor extensive genetic and phenotypic variation both within and between these subspecies. Wild mice have been used to study a wide range of biological processes, including immunity, cancer, male sterility, adaptive evolution, and non-Mendelian inheritance. Despite the extensive variation that exists among wild mice, classical laboratory strains are derived from a limited set of founders and thus contain only a small subset of this variation. Continued efforts to study wild house mice and to create new inbred strains from wild populations have the potential to strengthen house mice as a model system.

AbstractWild house mice, naturally infected with Aspiculuris tetraptera were segregated according to their weight into six age groups. The prevalence of infection and the mean worm burden of these mice were studied in the different age groups. The overall prevalence of infection was high (57% or more) in all the groups except the youngest. Mice acquired larvae soon after weaning; the highest larval burdens were reached in juvenile mice and the highest mature worm burdens, a group later, in mature mice. Older mice had fewer larvae and fewer mature worms. The mature worm burdens decreased but relatively slower than the larval burdens. It is suggested that either innate or acquired resistance could account for these observations.

<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>
