Influenza B outbreak on a cruise ship off the São Paulo Coast, Brazil.

Background: In February 2012, crew and passengers of a cruise ship sailing off the coast of São Paulo, Brazil, were hospitalized for acute respiratory illness (ARI). A field investigation was performed to identify the disease involved and factors associated.

Methods: Information on passengers and crew with ARI was obtained from the medical records of hospitalized individuals.

IgG antibody responses in mice coinfected with Toxocara canis and other helminths or protozoan parasites.

The immune response expressed by IgG antibodies in BALB/c mice experimentally infected with Toxocara canis, was studied with the aim of verifying the possible in vivo cross-reactivity between antigens of T. canis and other parasites (Ascaris suum, Taenia crassiceps, Schistosoma mansoni, Strongyloides venezuelensis and Toxoplasma gondii). Experiments included three groups of mice: one infected only by T.

Behavioral changes in Rattus norvegicus experimentally infected by Toxocara canis larvae.

Toxocara canis is a common canine nematode parasite and one of its possible transmission mechanisms is the predation of infected rodents by canids. Fifty Rattus norvegicus were used to study behavioral alterations in rodents infected by T. canis larvae.

Muscular strength decrease in Rattus norvegicus experimentally infected by Toxocara canis.

The muscular strength of experimental infected Rattus norvegicus with 3rd. stage Toxocara canis larvae was investigated. Fifty Wistar rats, divided in three groups (G1-20 rats infected by 300 eggs of T.

[Effects of cyclosporin A or betamethasone on experimental murine toxocariasis].

The effects of administration of either cyclosporin A or betamethasone 15 days before or 45 days after experimental infection with Toxocara canis on mice had been studied. The dynamics of IgG antibody production, employing an enzyme-linked immunosorbent assay, was studied 60 and 90 days after mice infection by Toxocara canis. In the 90th day after infection all surviving mice were sacrificed and the tissue trapped larvae recovered by acid digestion in the muscles, lungs, liver and brain.
