The aim of this study is to evaluate the effects of yeast extract (EPL) in the moist diet on the fecal microbiotal, gas production and intestinal morphology of adult cats. Twenty adult cats from both sexes were randomly assigned to four treatments: 1) moist commercial diet (control); 2) control + 0,2% yeast extract dry matter; 3) control + 0,4%; and 4) control + 0,6%. Fecal microbiology and intestinal morphology were performed by radiographic, ultrasound, colonoscopy and intestinal biopsy exams for histology. There were no significant differences (P>0,05) for lactic acid bacteria counts and clostridium-reductor, gas area in the bowel (radiographic), wall thickness of the colon (ultrasound) and colonocytes count/globet cells (histology). Through colonoscopy, changes in characteristics of the intestinal mucosa in animals receiving treatment 4 were noticed. It is concluded that the addition of up to 0.6% EPL had no effect on the parameters evaluated, but further studies are needed to understand the action mechanisms and additive effects for domestic cats.

OBJECTIVE: To verify the existence of fungal contamination prior to and following the cleaning and disinfection process of hospital mattresses used by patients with Candidemia. METHODS: Cross-sectional study analyzing 25 mattresses used by patients with Candidemia confirmed by blood culture from different hospital wards. The study made use of convenience samples. After growing the samples in an Agar Sabouraud Dextrose environment, isolated yeasts were identified by macroscopic, microscopic and physiologic characteristics. RESULTS: Analyses showed 15 (60%) mattresses contaminated by Candida spp. From these, 10 (66.7%) and five (33.3%) mattresses corresponded respectively to the collection prior to and following disinfection, with Candida parapsilosis being the isolated species with the highest frequency. CONCLUSION: Considering that half of the mattresses remained contaminated after cleaning and disinfection, there is a risk that these mattresses may act as potential secondary reservoirs in the infection chain.

This study aimed to assess the incidence of fungi and nematodes in Brachiaria sp. and Panicum maximum seeds produced in the Brazilian states of Mato Grosso do Sul (MS), Mato Grosso (MT), Goiás (GO), Minas Gerais (MG) and São Paulo (SP). The main fungi found in the seeds were Bipolaris sp., Curvularia sp. and Phoma sp.. The lowest incidence of these fungi was found for seeds of Brachiaria brizantha cultivars BRS Piatã and Xaraés, and Brachiaria decumbens cv. Basilisk, from the states of GO, MG and MS, respectively. The cultivars Marandu and BRS Piatã, from several regions, exhibited high occurrence of Aphelenchoides sp. and Ditylenchus sp.. Seeds of B. humidicola cultivar Humidicola, produced in MS and SP, did not show association with nematodes. The seeds of Panicum maximum cv. Massai and cv. Mombaça showed higher incidence of Bipolaris sp., Cladosporium sp., Curvularia sp., Fusarium sp. and Phoma sp., as well as Aphelenchoides sp. and Ditylenchus sp., especially for seeds produced in MT. Some of the detected pathogens are causative agents of diseases of major importance in forage plants, such as Bipolaris sp., causing leaf spot in Panicum, of high severity in Tanzânia, which provides serious compromising of the pasture sustainability.
