37. Insertion sequences as variability generators in the Mycoplasma hyopneumoniae and M. synoviae genomes
We have analyzed the sequenced genomes of three strains of Mycoplasma hyopneumoniae and one strain of M. synoviae, and have found three and two different transposable element families, respectively in each species. In M. hyopneumoniae, the Insertion Sequences of the IS4 family is represented by ISMHp1, a putatively active element. The IS3 family is represent

38. Differential metabolism of Mycoplasma species as revealed by their genomes
The annotation and comparative analyses of the genomes of Mycoplasma synoviae and Mycoplasma hyopneumonie, as well as of other Mollicutes (a group of bacteria devoid of a rigid cell wall), has set the grounds for a global understanding of their metabolism and infection mechanisms. According to the annotation data, M. synoviae and M. hyopneumoniae are able to

39. ABC transporters in Mycoplasma hyopneumoniae and Mycoplasma synoviae: insights into evolution and pathogenicity
ABC transporters represent one of the largest superfamilies of active membrane transport proteins (MTPs) with a highly conserved ATPase domain that binds and hydrolyzes ATP, supplying energy for the uptake of a variety of nutrients and for the extrusion of drugs and metabolic wastes. The complete genomes of a non-pathogenic (J) and pathogenic (7448) strain o

40. Restriction-modification systems in Mycoplasma spp
Restriction and Modification (R-M) systems are present in all Mycoplasma species sequenced so far. The presence of these genes poses barriers to gene transfer and could protect the cell against phage infections. The number and types of R-M genes between different Mycoplasma species are variable, which is characteristic of a polymorphism. The majority of the

41. Genes involved in cell division in mycoplasmas
Bacterial cell division has been studied mainly in model systems such as Escherichia coli and Bacillus subtilis, where it is described as a complex process with the participation of a group of proteins which assemble into a multiprotein complex called the septal ring. Mycoplasmas are cell wall-less bacteria presenting a reduced genome. Thus, it was important

42. Modulação da expressão dos genes EF1A e PTI-1 no câncer de próstata
Prostate cancer (PCa) has become a serious problem of public health for men. It is the second most diagnosed cancer, and even with the improvement of the clinical, histopathology and chemical techniques of detection, there is still a high mortality rate in consequence of the delayed or inefficient diagnosis of the illness. Finding more specific markers to in

43. Production and Evaluation of Recombinant Subunit Vaccine Against Swine Enzootic Pneumonia / Produção e avaliação de uma vacina de subunidade recombinante contra a pneumonia enzoótica suína
A Pneumonia Enzoótica Suína (PES), causada pela bactéria Mycoplasma hyopneumoniae, é a doença respiratória mais importante na suinocultura. As vacinas convencionais utilizadas para controlar esta doença consistem de bacterinas, que apresentam custo de produção elevado e eficiência limitada. O objetivo deste estudo foi desenvolver e avaliar uma nova

44. Diagnóstico da pneumonia enzoótica suína pela técnica da imunoperoxidase
Avaliou-se a técnica da imunoperoxidase como método auxiliar para a detecção de Mycoplasma hyopneumoniae em suínos naturalmente infectados. Foram colhidos 80 fragmentos de pulmões de 40 animais provenientes de granjas consideradas negativas e 40 de granjas com diagnóstico positivo de pneumonia enzoótica. Com a utilização de soro policlonal específ

45. Avaliação da resposta sorológica de suínos SPF inoculados com Mycoplasma hyopneumoniae
Three specific pathogen free (SPF) groups of pigs were inoculated with Mycoplasma hyopneumoniae intratracheally (group A) and three other ones with Mycoplasma flocculare intranasally (group B). Five SPF pigs of each group were exposed by contact with the inoculated pigs. A group of eight pigs were kept as control (group C), below the same others groups pigs

46. Mycoplasma hyopneumoniae Increases Intracellular Calcium Release in Porcine Ciliated Tracheal Cells
We investigated the effects of intact pathogenic Mycoplasma hyopneumoniae, nonpathogenic M. hyopneumoniae, and Mycoplasma flocculare on intracellular free Ca2+ concentrations ([Ca2+]i) in porcine ciliated tracheal epithelial cells. The ciliated epithelial cells had basal [Ca2+]i of 103 ± 3 nM (n = 217 cells). The [Ca2+]i increased by 250 ± 19 nM (n = 47 ce

47. Mycoplasma hyopneumoniae Potentiation of Porcine Reproductive and Respiratory Syndrome Virus-Induced Pneumonia
An experimental model that demonstrates a mycoplasma species acting to potentiate a viral pneumonia was developed. Mycoplasma hyopneumoniae, which produces a chronic, lymphohistiocytic bronchopneumonia in pigs, was found to potentiate the severity and the duration of a virus-induced pneumonia in pigs. Pigs were inoculated with M. hyopneumoniae 21 days prior

48. Oral immunization of mice with attenuated Salmonella typhimurium aroA expressing a recombinant Mycoplasma hyopneumoniae antigen (NrdF).
Mycoplasma hyopneumoniae is the etiological agent of porcine enzootic pneumonia, a commercially expensive respiratory disease of swine. Salmonella typhimurium SL3261 was used as a live carrier of plasmid pKF1, which encodes a 15-kDa recombinant M. hyopneumoniae protein. This expressed recombinant protein consists of the carboxy-terminal 11 kDa of a 42-kDa M.
