Journal Article
To determine the feeding sites preferred by adult gold-spotted pond frogs, Rana plancyi chosenica, and the foods that induce favorable growth of the frogs in the laboratory, we conducted two separate ...experiments between 27 May and 12 July 2007 in a vivarium. In the first experiment, we counted the number of crickets eaten by four gold-spotted pond frogs in a 60 min period at four different feeding sites within the experimental arenas: on the water surface, at the edge of a pond, and at two terrestrial sites.

Relata-se inusitado achado de micro-organismos, semelhantes às espiroquetas, móveis e de diferentes morfologias e tamanhos, identificados pela microscopia de campo escuro, no sangue de animais do ...Centro de Bioterismo da Faculdade de Medicina da USP. As bactérias não crescem em meios habituais de cultivo, são pouco coradas pelo Giemsa e derivados da prata, e as provas sorológicas e moleculares foram negativas para Borrelia e Leptospira. A microscopia eletrônica revelou presença de micro-organismos com morfologia de Mycoplasma e, devido à sua mobilidade, sugeriu-se a presença de Mollicutes do gênero Spiroplasma. Visualizaram-se micro-organismos com mesmas características em 15 dos 26 funcionários (57,6%) do Centro de Bioterismo da FMUSP; contudo, exames clínicos e laboratoriais indicaram que os indivíduos estavam saudáveis. Estudos adicionais desenvolvidos na Disciplina de Reumatologia da FMUSP mostraram que, aproximadamente, 94% dos pacientes com Síndrome Baggio-Yoshinari (SBY) e 20% dos indivíduos normais também exibiam as mesmas estruturas identificadas no Centro de Bioterismo. A microscopia eletrônica realizada com amostras de pacientes com SBY mostrou bactérias que apresentam semelhanças com Mycoplasma, Chlamydia e Bacteroides. Visto que as sorologias e os testes moleculares foram negativos para estes contaminantes e com base em publicações da literatura médica, sugeriu-se que estes agentes infecciosos latentes fossem bactérias na sua apresentação L, que são definidas como bactérias despojadas de parede celular, assumindo, assim, morfologia de Mycoplasma, sendo, na maioria dos casos, inofensivas aos hospedeiros. Concluímos que os "espiroquetídeos" visualizados em animais e funcionários do Centro de Bioterismo seriam bactérias na forma L, não patogênicas, provenientes de contaminantes do meio ambiente, infecções regulares habituais ou oriundos de micro-organismos endógenos da flora saprofítica normal. Ao contrário, os "espiroquetídeos" identificados na SBY, ao preservarem a capacidade de invadir células in vitro, são potencialmente patogênicos e relacionados com a etiologia da SBY. Interpretamos a SBY como zoonose nova e particular ao território brasileiro, causada por espiroquetas adaptadas às formas latentes, possivelmente provenientes de mutações bacterianas em resposta às condições ecológicas e geográficas próprias do país.We report the unusual finding of mobile spirochetal microorganisms with different morphologies and sizes, on dark-field microscopy of the blood of animals from the Vivarium of the Medical School of USP. The bacteria did not grow in common culture media, shows faint staining to Giemsa and silver-derived stains, and serologies and molecular tests were negative for Borrelia and Leptospira. Electron microscopy revealed the presence of microorganisms with Mycoplasma-like morphology and, due to its mobility, it was suggested that they represented Mollicutes of the genus Spiroplasma. Microorganisms with the same morphology were also observed in 15 out of 26 employees (57.6%) of the Vivarium of FMUSP; however, clinical and laboratorial exams indicated that those individuals were healthy. Additional studies undertaken at the Rheumatology Department of FMUSP demonstrated the presence of the same structures identified at the Vivarium in approximately 94% of the patients with Baggio-Yoshinary syndrome (BYS) and 20% of healthy individuals. Electron microscopy of the blood of BYS patients showed bacteria that shared similarities with Mycoplasma, Chlamydia, and Bacteroides. Since serologies and molecular tests were negative for those contaminants, and based on publications in the medical literature, it was suggested that those latent infectious agents were L-form bacteria, defined as cell wall deficient bacteria, assuming, therefore, Mycoplasma morphology and they are, for the most part, harmless to the host. We concluded that spirochetal microorganisms visualized in animals and employees of the Vivarium were non-pathogenic L-form bacteria from contaminants in the environment, regular infections, or endogenous microorganism from the normal saprophytic flora. On the other hand, spirochetal organisms identified in BYS, by preserving the capacity to invade cells in vitro, are potentially pathogenic and related to the etiology of BYS. We consider BYS as a novel Brazilian zoonosis caused by spirochetes adapted to their latent form, possibly due to bacterial mutations in response to ecologic and geographic conditions unique to Brazil.
