The purpose of this work was to evaluate the frequency of Malassezia pachydermatis infection and other infectious agents in dogs with external otitis and with healthy auditory tubes. Clinical manifestations of external otitis were evaluated. Samples from the auditory tube of 102 dogs with otitis and from 32 healthy dogs were submitted to direct microscopic examination and cultured in blood agar and Sabouraud dextrose agar with chloramphenicol and cycloheximide. Direct examination showed more than ten cells of M. pachydermatis in 52.0% of the samples from dogs with otitis, but in only 21.8% of the healthy auditory tube samples. M. pachydermatis was isolated in 37.5% of the samples from dogs with healthy auditory tube and 76.5% (p<0.01) of the samples...

Yeasts are commensal organisms found in the skin, genital and gastrointestinal tracts, and other mucosa in mammalians. Candida spp has been frequently isolated from domestic and sylvan animals. Yeast isolation from vaginal mucus is frequent in women, especially of Candida genus. In canine females, however, studies about vaginal fungal microbiota are rare and the connection with estrous cycle is unknown. The purpose of this study was to isolate yeast 5 of Candida genus from healthy canine females and identify the isolated species, establishing their connection with estrous cycle phases. Two hundred twenty-four samples taken from vaginal mucus of 14 canine females were analyzed in this study. Candida spp was observed in 83 (37%) from these samples; nine...

Using transmission electron microscopy, we studied the presence of melanin and cell wall thickness of clinical isolates of Sporothrix schenckii obtained from cats, dogs and humans as compared to reference strains. We detected differences regarding presence of the melanin among the clinical isolates of S. schenckii and a correlation between presence of melanin and cell wall thickness.

Malassezia pachydermatis is recognized as a normal inhabitant and an opportunistic pathogen of the external ear canal and skin of dogs and cats. In especial clinical conditions, and mainly in the cases of therapeutic failure related to external otitis and dermatitis complicated by this yeast, it is recommended test susceptibility to antifungal drugs. The purpose of this work was to evaluate the susceptibility of 44 isolates of M. pachydermatis from the external ear canal and skin of dogs and cats using two different in vitro antifungal susceptibility methods: the Etest® and the broth microdilution method. Thirty-five samples were tested using the Etest®, twenty-four samples were tested using the broth microdilution method and fifteen samples were tested...

The oral microbiota of humans and animals is made up of a wide variety of yeasts and bacteria, but microbiota of dogs is not totally described. Although such identification is an important step to establish the etiopathogenesis and adequate therapy for the periodontal disease The aim of this study was to evaluate and correlate oral alterations with the presence of yeasts in oral cavity of female dogs. After clinical evaluation samples from healthy and from dogs with oral diseases were obtained from three different oral sites by swabs, curettes, millimeter periodontal probes and HA membrane tip in cellulose ester. Yeast identification was performed through macroscopic and microscopic colony features and biochemical tests. Dental calculus was the most...

As drogas antifúngicas são classificadas em agentes químicos clássicos e atuais e em antibióticos. Os agentes químicos clássicos são aqueles medicamentos que apresentam de maneira geral espectro de ação reduzido contra fungos, atuando como fungistático de modo indireto ao modificar as condições locais, como por exemplo o iodo, os ácidos graxos e derivados, ácido salicílico, tolnaftato e tolciclato. Os agentes químicos atuais são representados pelos imidazóis e triazóis, flucitosina e alilaminas e os antibióticos representados pelos poliênicos (anfotericina B, nistatina e natamicina) e a griseofulvina. A descrição de cada antifúngico considerado será apresentada no trabalho.

ABSTRACT: The present study aimed to evaluate the use of aqueous wheat extracts as an adjunct to antineoplastic therapy with carboplatin. In this study, 32 rats were used which were randomly distributed into 4 groups: G1 - negative control; G2 - control treated with physiological solution; G3 - animals treated with aqueous extract of wheat in the concentration of 100mg/kg; G4 - animals treated with aqueous wheat extract at the concentration of 400mg/kg; 300mg/m² of carboplatin was administered intraperitoneally at day 0 in animals from groups G2, G3, and G4, whereas 1ml of physiological solution was administered by the same route in animals from group G1. Animals were treated daily for 21 days by orogastric gavage according to their respective...

ABSTRACT: Myiases occur by the infestation of fly larvae in tissues of live vertebrate animals, resulting in economic loss. Phytotherapy is considered an important alternative in the control of insects, which may reduce the economic impacts . Carapa guianensis is a plant that has been studied as a repellent against mosquitoes and Caesalpinia ferrea is reported in tropical climates, and there are few studies about its repellent action. The present study was designed to evaluate the repellent action of s C. guianensis and C. ferrea plants on flies species of the Calliphoridae family. W.O.T. traps containing deteriorated bovine liver and herbs cream of at concentrations of 20 and 50% were used to catch the flies. It was reported that the creams containing C....

A esporotricose é uma micose subcutânea, causada pelo fungo dimórfico Sporothrix schenckii. O presente estudo descreve a ocorrência de esporotricose felina na cidade de Pelotas (Rio Grande do Sul - Brasil), e a transmissão para um atendente da clínica veterinária, ocasionada pela arranhadura do animal doente. O felino apresentava deformação do espelho nasal e lesões cutâneas, enquanto o humano apresentava uma lesão ulcerada na região metacarpiana dorsal esquerda. Foram colhidas crostas e/ou exsudato das lesões do felino e do atendente para diagnóstico micológico, os quais foram cultivados em ágar Sabouraud dextrose acrescido de cloranfenicol e incubados a 25 e 37°C, durante 10 dias. O isolamento do S. schenckii confirmou o diagnóstico clínico de...
