Uso de resíduos de madeiras e frutos da amazônia para o cultivo in vitro do cogumelo comestível shiitake

Local abundant residues with low or without commercial value with potential to make the production of edible mushrooms economically viable in any region of Brazil must be employed for cultivation. Thus, the radial mycelial growth of LED 20 strain of Lentinula edodes (Berk.) Pegler was verified in culture media prepared with extract of regional residues by using substrates based on Protium puncticulatum, Cariniana micrantha and Caryocar glabum sawdust, supplemented with 20% of grinded residues from the barks of the fruits of Astrocaryum aculeatum and Theobroma grandiflorum. Residues from eucalyptus (Eucalyptus spp) sawdust and wheat bran (Triticum aestivum L) were used as witness because they are commonly used in the cultivation of L. edodes. The experimental design used was totally randomized, in 4x3 factorial scheme, totalizing 12 treatments with five repetitions, being that each repetition corresponded to a Petri dish, adding up a total of 60 dishes, which were incubated under 25 degrees C. The diameter of the colony was daily evaluated during seven days of incubation. After that period, it was verified that media prepared with P. puncticulatum extract, whose supplementation with both brans was favorable for fungic development, presented some of the highest averages of mycelial growth of LED 20 strain of L. edodes, confirming the potential of those residues.

Exogenous bacterial osteomyelitis in 52 dogs: a retrospective study of etiology and in vitro antimicrobial susceptibility profile (2000-2013)

Background: Most clinical cases of osteomyelitis in dogs involve infectious agents, especially bacteria and fungi. The characterization of these microorganisms may aid in the prevention and treatment of disease.Objective: The aim of this study was to evaluate retrospectively microbiological cultures and in vitro antimicrobial susceptibility profile of isolates from 52 cases of bacterial osteomyelitis in long bones of dogs over 2000-2013. In 78% of the cases injuries were caused by a motor vehicle accident, but there were a few cases of dog bites (17%) and ascending infection due to pododermatitis (5%).Animals and methods: The isolated microorganisms were identified based on conventional phenotypic methods. In vitro disk diffusion test was performed using 30 different antimicrobials.Results: The isolates were obtained from femur (28%), humerus (16%), tibia (31%), and radius/ulna (25%). Among 52 cases, culture was positive in 88% of cases. Thirteen genus of different species of microorganisms were isolated. The most common microorganisms isolated were Staphylococcus spp. and Escherichia coli followed by Streptococcus spp., enteric bacteria, Corynebacterium sp. and anaerobic bacteria. In 42% of cases cultures were mixed. The most effective drugs against isolated bacteria were amoxicillin and clavulanate potassium (79%) followed by ceftriaxone (69%). High-resistance rates were documented against azithromycin (80%), penicillin (59%), and clindamycin (59%).Conclusions: The present study highlights diverse etiologic agents in cases of infectious bacterial osteomyelitis, with predominance of Staphylococcus genus, and reinforces the importance of obtaining cultures and susceptibility profiles given the high rates of antimicrobial resistance.

Influência da luz LED na cultura celular de Mieloma múltiplo murino–NS1 in vitro

A monoclonal antibody (mAb) is an important tool in medical biotechnology and the production of biopharmaceuticals, especially for disease diagnosis and treatment of infections, because the antibodies have a significant advantage over chemical agents used in conventional therapies . The last thirty years the technology of production of monoclonal antibodies developed mainly the technique of obtaining in vitro, but also of their production is laborious, the cost is high. A major element of the high cost of production is the fact that the long-term culture consumes a large amount of imported inputs with high added value. A major contribution of this work is to promote cell growth more quickly and efficiently. Currently, a great race to discover new technologies and techniques to synthesize new antibodies and significantly increase the production of murine mAbs. New technologies such as laser and LED are innovations and widespread in modern life, so much so that its use has proliferated worldwide, primarily in the medical field. Recent studies show a series of results from the influence of the LED light in biological tissues such as: increasing the rate of cell proliferation, increased production rate of fibroblasts, increasing the rate of synthesis of RNA and DNA synthesis of ATP, etc. To assess the contribution of the LED in the culture of Myeloma NS1murino compared to the standard procedure. - NS1 cells were provided and followed the criteria of culture medium of the Laboratory of Cellular Engineering Center of Botucatu (POPs). The same amount of cells was grown in bottles of 25 cm2 polystyrene Tissue Culture Treated, specifically marked and kept in special medium RPMI 1640 Gibco BRL  supplemented with fetal bovine serum 10%, essential amino acids and non-essential, glucose, insulin and antibiotics. It was used in LEDs Cromatek wavelength of 630nm, 475nm and 530nm. The groups were... (Complete abstract click electronic access below)

Efeito do ácido tânico purificado (tanino) sobre o crescimento in vitro de isolados de Pythium insidiosum

Pythiosis is caused by the oomycetous Pythium insidiosum and affect domestic and wild animals and man. The presence of water and vegetal material is fundamental for its life cycle in nature. The biflagellate zoospore are the infective form of this pathogen. The lesions are generally of granulomatous aspect, which frequently may be contaminated by secondary bacterial infection in skin and subcutaneous tissue. Dissemination to systemic tissues may also occur and it may be due to the spread of the pathogen from cutaneous lesions, as well as a primary source of infection. Clinical signs depend on the affected tissue. Diagnosis of pythiosis is based on the clinical manifestations, histopathological sections and culture of the pathogen. Serological tests may also be employed and more recently molecular biology has been introduced as a sensitive, specific and a rapid method for conclusive diagnosis. Treatment is often difficult and extensive surgery procedures are required, however, depending on the anatomic region and size of the lesion, such procedure is unfeasible and relapses are frequent. Due to the climate changes, which has contributed to increase the incidence of pythiosis, it is necessary the search for new therapeutic protocols
