Bullfrog hemogram under management stress

Stress is one of the major obstacles in frog culture and can be caused by factors such as inappropriate farming systems; inadequate management among other situations. The objective of the present study was to assess the hemogram, erythrogram and leukogram of bullfrogs (L. catesbeianus) when exposed to stress caused by different types of management: density and handling (manipulation), developed in the laboratory and repeated in the field for the appropriate comparisons in a experimental period of 30 days. The density experiment was conducted with four treatments: 70 animals m(-2) (D70); 100 animals m(-2) (D100), Control; 150 animals m(-2) (D150) and 200 animals m(-2) (D200), with 10, 14, 21 and 28 animals/box in the laboratory, respectively. Each treatment was performed with three simultaneous replicates. The handling experiment was conducted with three treatments: Treatment Without Handling (WH); Treatment with Partial Handling (PH) every 15 days and Treatment with Total Handling (TH) every 15 days. Each treatment was performed with four simultaneous replications. The methodology of the blood analysis followed international recommendations. In the present study we could observe that the animals of the field experiment did not reflect the same stress response observed in the laboratory in both experiment, which demonstrated the plasticity of these animals.

The importance of retesting the hearing screening as an indicator of the real early hearing disorder

Early diagnosis of hearing loss minimizes its impact on child development. We studied factors that influence the effectiveness of screening programs. To investigate the relationship between gender, weight at birth, gestational age, risk factors for hearing loss, venue for newborn hearing screening and pass and fail results in the retest. Prospective cohort study was carried out in a tertiary referral hospital. The screening was performed in 565 newborns through transient evoked otoacoustic emissions in three admission units before hospital discharge and retest in the outpatient clinic. Gender, weight at birth, gestational age, presence of risk indicators for hearing loss and venue for newborn hearing screening were considered. Full-term infants comprised 86% of the cases, preterm 14%, and risk factors for hearing loss were identified in 11%. Considering the 165 newborns retested, only the venue for screening, Intermediate Care Unit, was related to fail result in the retest. Gender, weight at birth, gestational age and presence of risk factors for hearing loss were not related to pass and/or fail results in the retest. The screening performed in intermediate care units increases the chance of continued fail result in the Transient Otoacoustic Evoked Emissions test.

Avaliação da biodegradação de tolueno por fungos isolados de ambientes associados ao petróleo

Spills can ocurr during oil productive chain and contaminate various environments due to the toxicity of monoaromatics hidrocarbons. Toluene stands out for being agressive to the nervous sistem and teratogenic, with high mobility and solubility in water, which facilitates environmental impact. Studies show that fungi are potential aromatic compounds assimilators, encouraging new researches about its use on the recovery of contaminated sites. This study aimed to select and characterize fungus with potential for biorremediation of toluene. 50 fungi were selected of the Collection of Microorganisms of Interest for Oil Gas and Biofuels, of UNESP Rio Claro, all of which were isolated from sites contaminated with monoaromatic hydrocarbons. Two trials were realized to select the microorganism with greater potential. The first test evaluated fungal growth under toluene saturated atmosphere. 24 fungi were chosen because its greater biomass production to participate in the next trial, the degradation in plates test, where the blue redox agente, DCPIP, indicates the degradation reaction, turning colorless. From this teste was possible to select one isolate which showed higher growth and stronger medium discoloration as the microorganism with the greatest potential to assimilate toluene. The Trichoderma cf. koningii had its potential evaluated through gas cromatography. The experiment proved the efficiency of the methodology, with positives results from the method validation and the effectiveness demonstrated of the LA-PHA-PACK bottles to prevent the volatilization of toluene during the 21 days of experiment. Being reliable its use for monitoring toluene decay associating it with degradation. This results are important because there aren't many methodologies and vials efficient to the purpose of this work. In the present study the degradation rates demonstrated no significant decay of the concentration of hydrocarbon. That may be related to the...

Atividade inibitória de extratos de plantas da savana brasileira sobre microrganismos superinfectantes e oportunistas

A utilização de compostos naturais na medicina de populações tradicionais é uma realidade em todo o mundo e o cerrado brasileiro apresenta grande diversidade de vegetais com uso potencial no tratamento de infecções por microrganismos oportunistas. Esse estudo avaliou a atividade antimicrobiana dos extratos vegetais do cerrado brasileiro sobre microrganismos oportunistas e superinfectantes. Nos testes foram preparados extratos hidroalcoólicos e aquosos de 22 espécies de plantas utilizadas nas regiões Norte, Nordeste e Centro-Oeste como parte da medicina popular. Esses extratos foram testados sobre Enterococcus faecalis ATCC 19433 e Pseudomonas aeruginosa ATCC 10145 e dez isolados clínicos de cada uma dessas espécies microbianas. Inicialmente foi realizada uma triagem para se determinar a atividade antimicrobiana dos extratos. Em seguida, foram realizados testes para avaliar a maior diluição inibitória dos extratos por meio do método de diluição em caldo e testes de atividade inibitória em biofilme. Os resultados demonstraram que embora aproximadamente 20% de todos os extratos mostraram atividade inibitória sobre algum dos microrganismos alvo, os mais ativos foram os extratos aquosos e hidroalcoólicos de araçá e aroeira, se mostrando ativos frente a todos os microrganismos.
