In Brazil, human fungal infections are prevalent, however, these conditions are not officially reportable diseases. To estimate the burden of serious fungal diseases in 1 year in Brazil, based on available data and published literature. Historical official data from fungal diseases were collected from Brazilian Unified Health System Informatics Department (DATASUS). For fungal diseases for which no official data were available, assumptions of frequencies were made by estimating based on published literature. The incidence (/1000) of hospital admissions for coccidioidomycosis was 7.12; for histoplasmosis, 2.19; and for paracoccidioidomycosis, 7.99. The estimated number of cryptococcal meningoencephalitis cases was 6832. Also, there were 4115 cases of Pneumocystis pneumonia in AIDS patients per year, 1 010 465 aspergillosis and 2 981 416 cases of serious Candida infections, including invasive and non-invasive diseases. In this study, we demonstrate that more than 3.8 million individuals in Brazil may be suffering from serious fungal infections, mostly patients with malignant cancers, transplant recipients, asthma, previous tuberculosis, HIV infection and those living in endemic areas for truly pathogenic fungi. The scientific community and the governmental agencies should work in close collaboration in order to reduce the burden of such complex, difficult-to-diagnose and hard to treat diseases.

Respiratory viral infections are frequent causes of morbidity in transplant patients. We screened symptomatic adult transplant recipients for respiratory viruses in a cohort of patients attending a referral medical center in Brazil. The duration of viral shedding and the prevalence of viral codetections were also determined. During a 1-year period (2011-2012), swabs were obtained from 50 patients. An in-house polymerase chain reaction panel designed to detect 10 viruses was used. Viruses were identified in 19 (38%) patients, particularly parainfluenza III (32%) and the respiratory syncytial virus (20%); multiple viruses were identified in 26% of patients. Prolonged viral shedding was observed with 60% of individuals excreting viruses for >10 days. The clinical and epidemiologic relevance of prolonged viral shedding remains to be determined.

-The external ant community of Hospital Municipal de Morrinhos, in Morrinhos, Goiás State, was characterized by the low rates of richness, diversity, dominance and equity of species abundance. Pheidole sp.1, a polygynic species was numerically dominant in this environment, although it coexists with potentially competitive species. This ant species prevailed within all hospital departments and its space-time distribution was a little aggregated (variance/mean ratio = 1.102, χ 2 = 29.38, P < 0.01). Escherichia, Salmonella, Aeromonas, Enterococcus, Staphylococcus and Klebsiella were the bacteria associated to this ant species in nearly all hospital annexes. The unicolonialism of Pheidole sp.1 tends to increase the contamination and dissemination process of infecto-contagious agents. The control and management of this ant species must be followed by practices that reduce the colonization process by other queens and the quantity of site nidifi cation within the hospital.KEY WORDS: Urban ant, Pheidole, polygyny, community RESUMO -A comunidade de formigas da área externa ao hospital do Hospital Municipal de Morrinhos, GO, caracterizou-se pelos baixos índices de riqueza, diversidade, dominância e eqüidade de abundância das espécies. Pheidole sp.1, uma espécie poligínica, dominou esse ambiente apesar da coexistência com espécies potencialmente competitivas. A mesma espécie de formiga predominou no interior de praticamente todas as repartições do hospital e sua distribuição espaço-temporal aproximou-se da agregada (variância/média = 1.102, χ 2 = 29.38, P < 0.01). Escherichia, Salmonella, Aeromonas, Enterococcus, Staphylococcus e Klebsiella foram os gêneros de bactérias associados a essa espécie de formiga em praticamente todas as repartições do hospital. O unicolonialismo de Pheidole sp.1 tende a potencializar o processo de contaminação e disseminação de agentes infecto-contagiosos. O manejo e controle da espécie devem ser acompanhados de técnicas que reduzam o processo de colonização por novas rainhas e a quantidade de locais de nidifi cação no interior do hospital. PALAVRAS-CHAVE: Formiga urbana, Pheidole, poliginia, comunidadeVárias espécies de formigas se beneficiam com a presença do homem, tanto na zona rural como na urbana, e algumas destacam-se como pragas devido aos problemas ocasionados direta ou indiretamente à população humana (Vinson 1986, Vander Meer et al. 1990. Espécies de formigas que vivem no interior de edifi cações em ambiente urbano são caracterizadas pelo tamanho corporal pequeno, poliginia, mobilidade das colônias e unicolinialismo (Passera 1994). As principais espécies consideradas pragas urbanas no Brasil são exóticas, destacando-se Monomorium pharaonis (L.), Monomorium fl oricola Jerdon, Paratrechina longicornis (Latreille) e Tapinoma melanocephalum (Fabricius) . Linepithema humile (Mayr), Paratrechina fulva (Mayr), Wasmannia auropunctata (Roger) e algumas espécies de Camponotus, Pheidole, Brachymyrmex e Solenopsis, nativas do Brasil, também são importantes pragas urbanas.A infecção hospi...

The fecal coliform can contaminate water of human consumption causing problems to public health. Many of these microorganisms may contain plasmid and transfer them to other bacteria. This genetic material may confer selective advantages, among them resistance to antibiotics. The objectives of this study were to analyze the presence of fecal coliforms in water and at drinker surface, to identify the existence of plasmid, conducting studies of resistance to antibiotics, plasmid stability and capacity of bacterial conjugation. Were collected microorganisms in water of drinker surface and were used specific culture media and biochemical tests for identification of organisms, tests were performed by checking the resistance to antibiotics (ampicillin 10 μg, tetracycline 30 μg, and ciprofloxacin 5 μg), was performed extraction of plasmid DNA, plasmid stability and bacterial conjugation. Was obtained results of 31% of Salmonella spp. and 51% for other coliforms. Among the samples positive for coliforms, 27 had plasmid stable and with the ability to perform conjugation. The plasmids had similar forms, suggesting that the resistance in some bacteria may be linked to those genes extra chromosomal.

Lignocellulosic wastes can be potentially converted into several bioproducts such as glucose, xylo‐oligosaccharides, and bioethanol. Certain processes, such as enzymatic hydrolysis, are generally needed to convert biomass into bioproducts. The present study investigated the production of xylanases and cellulases by Streptomyces thermocerradoensis I3 under solid‐state fermentation (SSF), using wheat bran as a low‐cost medium. The activities of xylanase and carboxymethyl cellulase (CMCase) were evaluated until 96 hr of incubation. The highest enzyme activity was observed after 72 hr of incubation. The crude enzyme extract was sequentially filtered, first using a 50 kDa filter, followed by a 30 kDa filter. Fraction 3 (F3) exhibited activities of both xylanase and CMCase. Xylanase and CMCase showed optimum activity at 70°C and pH 6.0 and 55°C and pH 6.0, respectively. The zymogram analysis showed a single activity band with a molecular mass of approximately 17 kDa. These findings provide strong evidence that the enzyme is a bifunctional xylanase/endoglucanase. This enzyme improved the saccharification of sugarcane bagasse by 1.76 times that of commercial cellulase. This enzyme has potential applications in various biotechnological procedures.

Introduction: Goiás State, which is in the midwest region of Brazil, has several urban forests. This fact, along with the expansion of urban areas within the limits of Forest Conservation Units, increases the contact between humans and wildlife, such as capuchin monkeys. The impulsive behavior of these animals and the scarcity of food cause them to vigorously search for food, leading to direct encounters with Park visitors, which can result in scratches and bites and making them potential disseminators of pathogenic microorganisms. Methods: Ten specimens of bearded capuchin monkey (Sapajus libidinosus) were captured at the Onofre Quinan Environmental Park in Anápolis, Goiás, Brazil. Samples were collected from the monkeys, and the bacteria and fungi present in the samples were isolated and identified. Then, the identified microorganisms were subjected to antibiotic susceptibility testing. Results: A total of 111 bacteria and 12 fungi were isolated, including two strict anaerobic bacteria of the genus Peptostreptococcus, 109 facultative anaerobic bacteria, and 12 yeasts. Among the facultative bacteria, enterobacteria and Staphylococcus were common. Resistance to tetracycline and ampicillin antibiotics was detected in the enterobacteria, and resistance to tetracycline, erythromycin, and clindamycin was detected in the Staphylococci. The other strains were sensitive to all tested antimicrobials. Cefoxitin showed 100% efficacy in all isolated bacteria. Conclusions: For bites from capuchin monkeys, we recommend performing complete hygiene and antibiotic therapy, according to medical recommendations. Given the 100% effectiveness of cefoxitin, it should be considered for this type of injury, especially in the study region.
