25. Genes involved in translation of Mycoplasma hyopneumoniae and Mycoplasma synoviae
This is a report on the analysis of genes involved in translation of the complete genomes of Mycoplasma hyopneumoniae strain J and 7448 and Mycoplasma synoviae. In both genomes 31 ORFs encoding large ribosomal subunit proteins and 19 ORFs encoding small ribosomal subunit proteins were found. Ten ribosomal protein gene clusters encoding 42 ribosomal proteins

26. 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

27. 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

28. 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

29. 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

30. A model for the RecA protein of Mycoplasma synoviae
In this work, we predict a structural model for the RecA protein from M. synoviae (MsRecA) by theoretical homology modeling and evaluate the occurrence of polymorphisms in this protein within several isolates of this species. The structural model suggested for MsRecA conserves the main domains present in MtRecA and EcRecA. The L1 and L2 regions showed six an

31. Serologic response of SPF chickens to live vaccines and other strains of Mycoplasma gallisepticum
False positive serologic reactions and difficulties in the diagnosis of Mycoplasma gallisepticum (MG) in chickens have increased lately as a result of infection by low virulent MG strains and the use of live MG vaccines in poultry. The objective of this study was to evaluate the serologic responses of SPF chickens exposed to the three commercially available

32. Detecção da infecção de rotavírus e levantamento soroepidemiológico de alguns patógenos com potencial zoonótico em avestruzes (Struthio camelus) no Estado do Paraná / Detection of rotavirus infection and serosurvey of some pathogens with zoonotic potential in ostriches (Struthio camelus) in Paraná State
A criação industrial de avestruzes no Brasil tem crescido nos últimos anos, mas avestruzes podem ser reservatórios de agentes com potencial zoonótico, como é o caso do vírus da influenza, rotavírus, vírus da encefalomielite eqüina do leste (EEEV) e do oeste (WEEV), salmonela, leptospira e micoplasma. O objetivo deste trabalho foi detectar rotavíru

33. Avian mycoplasmosis update
Avian mycoplasmas occur in a variety of bird species. The most important mycoplasmas for chickens and turkeys are Mycoplasma gallisepticum (MG), M. synoviae (MS), and M. meleagridis. Besides, M. iowe (MI) is an emerging pathogen in turkeys, but of little concern for chickens. Mycoplasmas are bacteria that lack cell wall and belong to the class Mollicutes. Al

34. Infectious laryngotracheitis virus: detection and molecular characterization, isolation, differential diagnosis and epidemiology of an outbreak in commercial layer flocks in Bastos region, São Paulo State / Vírus da laringotraqueíte infecciosa: detecção e caracterização molecular, isolamento, diagnóstico diferencial e epidemiologia de um surto em granjas de poedeiras comerciais na região de Bastos, Estado de São Paulo
O presente trabalho descreve o desenvolvimento de uma técnica de nested-PCR para a detecção de ADN do vírus da laringotraqueíte infecciosa (VLTI) utilizando primers que amplificam uma região do gene que codifica a glicoproteína E viral. A técnica padronizada amplificou amostras isoladas e de campo, mostrando alta sensibilidade e especificidade tomand

35. Test profiles of broiler breeder flocks housed in farms with endemic Mycoplasma synoviae infection
There is a need for a better understanding of the epidemiology of Mycoplasma synoviae (MS) infection in broiler breeders in Brazil. Many features of the infection remain unrecognizable, because there are no clinical signs of the disease. A detailed testing was performed at each 6 to 8 weeks in three MS-free flocks introduced in farms with endemic MS infectio

36. Resistance to Mycoplasma synoviae is Bursal Dependent
Bursectomizing small bursa line birds produced susceptibility to Mycoplasma synoviae. This suggested that M. synoviae is B cell dependent, but does not rule out a T cell effect.
