Fate of non O157 Shiga toxigenic Escherichia coli in composted cattle manure

Determinou-se o tempo necessário para a eliminação de Escherichia coli Shigatoxigênica (STEC) não-O157 em esterco bovino composto, obtido de fezes frescas de três vacas portadoras de cepas STEC não-O157 que apresentavam o gene stx 2. Foram utilizados dois sistemas de compostagem, o primeiro foi um buraco de 0,6m escavado no solo e o segundo um monte apresentando uma arquitetura piramidal com um metro de altura. Todos os dias, durante os primeiros 10 dias e a cada cinco dias durante um mês, uma amostra de três pontos diferentes dos dois sistemas de compostagem foram coletadas e semeadas para determinar a presença de E. coli e a presença do gene stx 2 nas células, sendo que em cada coleta a temperatura do sistema de compostagem foi determinada. Células de STEC não-O157 sobreviveram por 8, 25 e 30 dias nas temperaturas de 42, 40 e 38ºC, respectivamente, no sistema enterrado no solo, enquanto que no sistema de monte as células foram detectadas por 4, 4 e 7 dias em temperaturas de 65, 58 e 52ºC, respectivamente. A temperatura e os microrganismos presentes na microbiota do sistema de compostagem parecem ser os responsáveis pela eliminação do patógeno. Pode-se concluir que os dois sistemas de compostagem utilizados mostraram-se eficientes na eliminação de células de STEC. A aplicação de esterco após compostagem deve diminuir o risco de contaminação ambiental e a disseminação do patógeno.

Lutzomyia longipalpis (Diptera, Psychodidae) em Cuesta Basáltica, na bacia hidrográfica do Rio Corumbataí, Região Centro-leste do Estado de São Paulo

A incidência das leishmanioses tegumentar e visceral americanas, em especial esta última (LVA), em hospedeiros caninos e humanos, encontra-se em crescente processo de expansão no Estado de São Paulo. Para a vigilância epidemiológica dessas endemias, torna-se fundamental o conhecimento da distribuição e da ecologia das diferentes espécies da fauna flebotomínea vetoras. Assim, a divulgação de novos encontros de seus vetores, sobretudo da Lutzomyia longipalpis, o principal vetor da LVA, é fundamental para apontar novas áreas de risco para a transmissão dessas doenças. Neste estudo, capturas de flebotomíneos foram realizadas em ambiente domiciliar, peridomiciliar e de mata, em diferentes localidades rurais dos municípios de Ipeúna e Itirapina, entre outubro de 2001 e fevereiro de 2004. Foram utilizadas armadilhas luminosas automáticas do tipo CDC, das 18h às 8h, em 14 noites, resultando 420 horas de exposição. Foram capturados 177 flebotomíneos pertencentes a doze espécies. A espécie mais abundante, Nyssomyia neivai, apontada como a principal vetora de LTA no Estado, contribuiu com 85,4% dos espécimes capturados em Ipeúna. O encontro de Lutzomyia longipalpis em uma caverna em Itirapina, aponta para o risco de estabelecimento da LVA na área e a necessidade de mais estudos locais sobre sua ecologia, sobretudo em relação à ocupação de ambientes antrópicos.

AN ANATOMICAL STUDY OF THE LATEROTRIGEMINAL VENOUS SYSTEM

The middle cranial fossa of 100 cadavers were dissected under stereoscopic loupe in order to identify and systematize the venous vessels located along the lateral margin of the trigeminal cave. The author found that at the sensitive root and trigeminal ganglion level a dural venous canal was present in most individuals examined and that the upper side of this canal communicated with the superior petrosal sinus. However, at the level of the lateral border of the intracranial segment of the mandibular nerve, venous lacunae were found to prevail, and these lacunae communicated with several other venous formations in the peritrigeminal region. The author concludes that the venous vascularization of this area constitutes a major risk in surgical interventions made in the middle cranial fossa. In addition, it is a relevant factor in the hemodynamics of the intracranial circulation.

Produtividade e qualidade de frutos do mamoeiro em função de tipos e doses de biofertilizantes

Biofertilizers are organic products usually obtained from an anaerobic process, evaluated mainly as phytoprotectors for agriculture, although they can improve fruit production. By this way, a field experiment was carried out in Remigio County, Paraiba State, Brazil, to evaluate the effects of two bovine biofertilizers on yield, medium mass and quality of papaya fruits (Carica papaya L.), 'Baixinho de Santa Amalia cultivar. Treatments were distributed in a randomized complete blocks design with three replications and 15 plants in each parcel, in a 2 x 5 factorial arrangement, with two biofertilizers: simple (water and fresh bovine manure) and supermagro (water, fresh bovine manure, macro and micronutrients and a protein mix), applied in soil under liquid form at five volumes, as follows: 0.0; 0.5; 1.0; 1.5; e 2.0 L cave(-1). There was no statistical difference between biofertilizers for fruit mass, yield and external and internal fruit quality variables, while between volumes differences were registered for both biofertilizers. The results, except for fruit firmness, registered positive effects of the biofertilizers on 'Baixinho de Santa Amalia' papaya cultivar in relation to yield and physical and chemical fruit quality.

CYTOGENETIC ANALYSIS OF THE BRAZILIAN BLIND CATFISH PIMELODELLA-KRONEI AND ITS PRESUMED ANCESTOR, P-TRANSITORIA

Karyotypes of the blind catfish Pimelodella kronei from three different caves in the southwestern part of the State of São Paulo, Brazil, and of its presumed ancestor Pimelodella transitoria were examined. Chromosome number and formula, as well as C-banding pattern and NOR location were found to be the same in both species, supporting the hypothesis of a close relationship and even conspecificity of P. kronei and P. transitoria.

IMPORTANCE OF CONTROLLING THE STRESS IN THE VALIDATION OF BIOLOGICAL RESULTS

The stress syndrome includes ample phenomena, characterized by complex neuroendocrinological alterations. Such alterations, in the long run, give rise to important modifications in reply of different organs and tissues to diverse agonists, specially sympathicommentic. These alterations, at least partially, are part of an ''adjustment mechanism'' of the tissues. Thus this possibility of obtaining altered responses in function of stress leads to the need of special care in the prevention and control of stressogenic stimuli in the process of research. Taking cave of preventing stressogenic stimuli, it becomes possible to determine a profile of trustworthy replies, considered as standard From such reply standards, toe can know more clearly what is a ''normal'' response or what is a response ''altered'' by some factor, specially stress.

Clavicular osteolytic lesions (45 to 60 days) appeared during paracoccidioidomycosis therapy. Recovery was observed 2 months after treatment of acute infantile paracoccidioidomycosis.

Capacidade de carga real (ccr) da caverna de santana, parque estadual turístico do alto ribeira (Petar) - sp, e indicações para o seu manejo turístico

The tourist use of Santana cave provides a row of environmental damages, compromising partially the pristine conditions. Among the measures adopted to avoid this situation, this issue presents a contribution for the physical limits to tourist visitation and the indications for speleotouristic management. It was used the Cifuentes Carrying Capacity method and some basic principles of Visitors Impact Management Framework - VIM. The results show a Real Carrying Capacity (CCR) about 120 visits daily on the cave. The discussions raise a few hypotheses about the alteration in the method used and the temporal frequency between visitors groups, suggesting a provisional CCR of 117 and 135 visitors daily, respectively, during the week and in the weekends and holidays. The conclusions appoint the necessity of a conceptual revision in the Carrying Capacity methods, mainly about its adaptation for tourist management in caves. In the case studied, it is suggested the immediate beginning of environmental monitoring of the cave, to verify the plausibility from proposed visitation limits and the possible contributions for to mitigate the environmental impacts from speleotourism.
