SURVEY OF FELINE LEUKEMIA VIRUS AND FELINE CORONAVIRUSES IN CAPTIVE NEOTROPICAL WILD FELIDS FROM SOUTHERN BRAZIL

A total of 57 captive neotropical felids (one Leopardus geoffroyi, 14 Leopardus pardalis, 17 Leopardus wiedii, 22 Leopardus tigrinus, and three Puma yagouaroundi) from the Itaipu Binacional Wildlife Research Center (Refugio Bela Vista, Southern Brazil) were anesthetized for blood collection. Feces samples were available for 44 animals, including one L. geoffroyi, eight L. pardalis, 14 L. wiedii, 20 L. tigrinus, and one P. yagouaroundi. Total DNA and RNA were extracted from blood and feces, respectively, using commercial kits. Blood DNA samples were evaluated by polymerase chain reaction (PCR) for feline leukemia virus (FeLV) proviral DNA, whereas reverse transcriptase-PCR was run on fecal samples for detection of coronavirus RNA. None of the samples were positive for coronaviruses. A male L. pardalis and a female L. tigrinus were positive for FeLV proviral DNA, and identities of PCR products were confirmed by sequencing. This is the first evidence of FeLV proviral DNA in these species in Southern Brazil.

Differentiation of field isolates and vaccine strains of infectious laryngotracheitis virus by DNA sequencing

Two different regions of the infected cell protein 4 (ICP4) gene of infectious laryngotracheitis virus (ILTV) were amplified and sequenced for characterization of field isolates and tissue culture-origin (TCO) and chicken embryo-origin (CEO) vaccine strains. Phylogenetic analysis of the two regions showed differences in nucleotide and amino acid sequences between field isolates and attenuated vaccines. The PCR-RFLP results were identical to those obtained by DNA sequencing and validated their use to differentiate ILTV strains. The approach using the sequencing of the two fragments of the ICP4 gene showed to be an efficient and practical procedure to differentiate between field isolates and vaccine strains of ILTV.

Central effects of Tityus serrulatus and Tityus bahiensis scorpion venoms after intraperitoneal injection in rats

A great number of studies on scorpion venoms associate their effects to the autonomic nervous system, and few data are available about their action on the central nervous system (CNS). The aim of this work was to evaluate some central effects after intraperitoneal injection of Tityus serrulatus or T. bahiensis scorpion venoms. The hippocampal concentration of some neurotransmitters and their metabolites were determined. Electroencephalographic and behavioral observations were performed, and all brains were removed for histopathological analysis of hippocampal areas. Both venoms induced electrographic and behavioral alterations despite T bahiensis venom affects less the electrographic activity than T. serrulatus venom. Neurochemical analysis demonstrated no alteration in the extracellular levels of almost all the neurotransmitters evaluated, at least in the hippocampus, and no neuronal loss in this area was observed. Meanwhile, extracellular concentration of HVA increased up to 10 times in approximately 1/3 of the animals of both groups. Scorpion venoms seem to exert a small but important central effect. More studies in this field are necessary because they may be useful in developing new strategies to reduce the damage caused by scorpion stings. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Detection and Molecular Characterization of Gene 3 and 5 of Turkey Coronavirus from Turkeys with Severe Enteritis in Brazil

Turkey coronavirus (TCoV) is a causative agent associated with poult enteritis and mortality syndrome (PEMS) in turkeys worldwide. The disease is an acute, highly contagious enteric disease that is characterized by depression, anorexia, diarrhea, and high mortality in commercial turkey flocks. The presence of TCoV in 12 intestinal-content samples, from turkey flocks aged between 10 and 104 days and exhibiting severe enteritis, was monitored during the period of 2004 to 2006. TCoV detection was accomplished by a reverse transcriptase-polymerase chain reaction (RT-PCR) through amplification of the 3` UTR region, followed by amplification of genes 3 and 5. Molecular characterization of the viruses was done through amplification of genes 3 and 5 and showed evidence of genetic similarity between them, although they differed from sequences of other TCoVs described in the literature. In relation to gene 3, samples showed a greater relationship with chicken infectious bronchitis virus (IBV), while gene 5 showed greater identity with pheasant coronavirus (PhCoV). Our results suggest that the strategy of amplification of the 3` UTR region, followed by sequencing of genes 3 and 5, has proven to be an effective means of detecting TCoV in intestinal contents.

Peripheral nervous system and grounds for the neural insult in leprosy

The mechanism of interaction between Mycobacterium leprae and neural cells has not been elucidated so far. No satisfactory interpretation exists as to the bacterium tropism to the peripheral nervous system in particular. The present study is a review of the micro-physiology of the extracellular apparatus attached to Schwann cells, as well as on the description of morphological units probably involved in the process of the binding to the bacterial wall.

Detection of cytokines and nitric oxide synthase in skin lesions of Jorge Lobo`s disease patients

Studies investigating the immunopathological aspects of Jorge Lobo`s disease have shown that the inflammatory infiltrate consists mainly of histiocytes and multinucleated giant cells involving numerous yeast-like cells of Lacazia loboi, with the T lymphocytes more common than B lymphocytes and plasma cells. The quantification of cytokines in peripheral blood mononuclear cells culture supernatant has revealed alterations in the cytokines profile, characterized by predominance of a Th2 profile. In view of these findings and of the role of cytokines in cell interactions, the objective of the present study was to investigate the presence of the cytokines IL-10, TGF-ss 1 and TNF-alpha, as well as iNOS enzyme in granulomas induced by L. loboi. Histological sections obtained from skin lesions of 16 patients were analyzed by immunohistochemistry for the presence of these cytokines and iNOS. The results showed that TGF-ss 1 was the cytokine most frequently expressed by cells present in the inflammatory infiltrate, followed by IL-10. There was a minimum to discrete positivity of cells expressing TNF-alpha and iNOS. The results suggest that the presence of immunosuppressive cytokines in skin lesions of patients with the mycosis might be responsible for the lack of containment of the pathogen as demonstrated by the presence of numerous fungi in the granuloma.

Influence of Orthognathic Surgery on Voice Fundamental Frequency

Considering that orthognathic surgery promotes changes in orofacial structures constituting the resonating system, functional changes secondary to surgery are expected to affect speech, leading to the need for further speech and voice adjustments. Thus, understanding the possible relationships of these structures with voice production is important. Therefore, this Study aimed to describe the changes in voice fundamental frequency of a patient submitted to orthognathic surgery and observe if there is a relationship with hyoid bone positioning at the different treatment periods. The results revealed that voice fundamental frequency increased after surgery, returning to values close to the preoperative condition, which corresponded to vertical movement of the hyoid bone.

A crise do transporte a??reo no Brasil: 2006-2007

Este estudo de caso aborda a crise vivida pelo setor de transporte a??reo brasileiro nos anos de 2006 e 2007. Deflagrada por um acidente de vulto, a crise teve como protagonistas os controladores de tr??fego a??reo, que, sob suspeita de falha funcional e comunica????o dif??cil com as autoridades do setor, reagiram por meio de uma estrat??gia de opera????o-padr??o (greve branca). Essa situa????o, somada ?? escassez de pessoal, provocou, de novembro de 2006 at?? meados de 2007, o descontrole operacional dos principais aeroportos do pa??s, com grandes preju??zos aos usu??rios. Um novo acidente a??reo, no decorrer da crise, agravou ainda mais a situa????o do setor, expondo defici??ncias estruturais e profissionais ?? opini??o p??blica brasileira, em uma ??rea at?? ent??o considerada segura. O caso relata as tentativas de equacionamento da crise por parte das autoridades respons??veis pela pol??tica de transporte a??reo, frente ao descontentamento e ??s reivindica????es dos controladores de tr??fego a??reo e ?? indigna????o da sociedade. O objetivo do estudo de caso ?? ilustrar uma situa????o de crise e de processo de negocia????o, tendo sido originalmente utilizado em uma oficina sobre negocia????es no setor p??blico. O caso pode ser utilizado como material de apoio em cursos que abordem, entre outros, os seguintes t??picos: negocia????o, gest??o de crises, comunica????o e planejamento estrat??gico
