Malassezia dermatitis in dogs in Brazil: diagnosis, evaluation of clinical signs and molecular identification.

Skin carriage and quantification of Malassezia yeasts were evaluated in 180 healthy dogs (group 1) and 117 dogs with clinical signs (pruritus, erythema, lichenification/seborrhoea, excoriations and alopecia) that could be related to Malassezia dermatitis (group 2) in Brazil. The lesions in the group 2 dogs were evaluated using CADESI-03 scores. Samples were collected from five different anatomical areas.

Nodular worm infection in wild chimpanzees in Western Uganda: a risk for human health?

This study focused on Oeosophagostomum sp., and more especially on O. bifurcum, as a parasite that can be lethal to humans and is widespread among humans and monkeys in endemic regions, but has not yet been documented in apes.

Evaluation of fungal aerosols using Temporal Temperature Gradient Electrophoresis (TTGE) and comparison with culture.

Information obtained from fungal air samples can assist in the assessment of health hazards and can be useful in proactive indoor air quality monitoring. The objective of the present study was to evaluate the PCR-TTGE technique for the analysis of fungal diversity in the air. Eleven air samples were collected in five different sites using the bioimpactor CIP 10-M (Arelco).

Pythiosis in Africa.

We report the first case of pythiosis from Africa in an 8-month-old dog with a chronic and ulcerative cutaneous lesion. The etiologic agent belonged to the genus Pythium. Phylogenetic analysis placed the isolate in a sister group to the other P.

Phylogenetic relationships among Pneumocystis from Asian macaques inferred from mitochondrial rRNA sequences.

The presence of Pneumocystis organisms was detected by nested-PCR at mitochondrial large subunit (mtLSU) rRNA gene in 23 respiratory samples from Asian macaques representing two species: Macaca mulatta and M. fascicularis. A very high level of sequence heterogeneity was detected with 18 original sequence types.
