Birds are hosts for a rich fungal microbiota which can act as potent pathogens for humans and other species of animals, causing thereby serious public health problems. The objective of this study was to evaluate the participation of birds kept in containers in the epidemiology of infectious diseases such as cryptococcosis and aspergillosis, thus verifying the maintenance and spread of pathogens in the environment. 36 samples of excretas of passeriformes were collected and were cultivated in Sabouraud Dextrose Agar 4% at room temperature and 37°C. The isolated fungal colonies were classified according to their morphological and staining characteristics. Subsequently, those in yeast form were peaked in Niger Agar, incubated at 30°C. In one sample showed growth of more than one type of colony and there was verified the presence of 25.0% of Penicillium spp., 19.4% of Trichosporon spp., 13.9% of C. gattii, 11.1% of C. neoformans, 11.1% of Candida spp., 8.3% of Rhizomucor spp., 8.3% of Aspergillus spp., 2.8% of Nigrospora spp. and 2,8% of Geotrichum spp. It can be conluded by the expost that birds shed continuously pathogenic microorganisms in their feces acting in definitive form in the infectious diseases ecoepidemiology.

This experiment aimed to determine the influence of supplementation with protected fat on nematode infections in periparturient sheep or sheep in their final stage of pregnancy. Fifty Santa Ines ewes received 200 g of concentrate/animal/day, mineral salt and water and were grouped according to their weight, hematocrit and the number of eggs per gram of feces (EPG). Two diets were used: a control treatment and a treatment consisting of supplementation with 30 g/animal/day of protected fat in the concentrate. Three monthly evaluations were performed over a total of 84 days of testing. The variables analyzed were weight, body condition, EPG and coprocultures; blood tests were performed for the determination of packed cell volume, hemoglobin concentration and total plasma protein, and leukograms and eosinophil counts were performed. For weight and hemoglobin concentrations, interactions were observed between diet and collection date (P<0.05); body condition, total plasma protein, packed cell volume and total leukocytes did not differ statistically among treatments (P> 0. 05) but did differ by collection day (P <0.05). The EPG and eosinophil counts did not differ statistically by either diet or collection date (P>0.05). The genus Haemonchus was predominant, followed by the genera Cooperia, Trichostrongylus and Oesophagostomum. The protected fat did not decrease EPG and did not improve the blood parameters of infected sheep.

In order to assess the occurrence and distribution of spores and toxins of Clostridium botulinum types C and D in three farms in Cocalinho, at the Araguaia River valley, State of Mato Grosso, Brazil, we analyzed sediment samples from 40 water holes, soil and cattle feces, collected around water holes. Sediments were analyzed by direct method, whilst feces, soil and also sediment samples were individually analyzed by indirect method. The detection of spores and botulinum toxins in the filtered material was performed by bioassay in Swiss Webster mice strain, as well as the serum-neutralization of the positive materials for typing. Samples of cattle feces showed the largest positive rate for C. botulinum, with 25/40 (62.5%), followed by soil, 12/40 (30%), and by sediment, 13/40 (32.5%). From the 40 cattle feces samples, 25 (62.00%) were positive for Clostridium botulinum; six samples were identified as type C, other six as type D, and 13 samples were classified as CD complex. From the equal number (40) of soil samples, 12 (30%) were positive for C. botulinum; two samples were identified as type C, other three as type D, and seven samples were classified as CD complex. Regarding the 40 sediment samples, 13 (32.5%) were positive for C. botulinum; two samples were identified as type C, other three as type D, and eight samples were classified as CD complex. No botulism toxin was detected by indirect method.
