Complex networks have been widely used to model biological systems. The concept of accessibility has been proposed recently as a means to organize the nodes of complex networks as belonging to its border or center. Such an approach paves the way to investigating how the functional and structural properties of nodes vary with their respective position in the networks. In this work, we approach such a problem in a biological context applying border detection to Protein-Protein Interaction networks from four organisms of the Mycoplasma genus...

A 7-month-old female infant had clinical and laboratory evidence of severe warm autoimmune hemolytic anemia. She also had clinical evidence of an upper respiratory tract infection with molecular detection of Mycoplasma pneumoniae. Although reticulocytopenic initially, she responded to red blood cell transfusion, steroids, and intravenous immunoglobulin and remains well today. With the increasing use of multiplex respiratory viral and bacterial pathogen detection systems, the rare association described in this report may prove to be more common than previously thought and may provide insight into the pathogenesis and clinical consequences of red blood cell autoantibodies...

In disease ecology, the host immune system interacts with environmental conditions and pathogen properties to affect the impact of disease on the host. Within the host, pathogens may interact to facilitate or inhibit each other's growth, and pathogens interact with different hosts differently. We investigated co-infection of two Mycoplasma and the association of infection with clinical signs of upper respiratory tract disease in four congeneric tortoise host species (Gopherus) in the United States to detect differences in infection risk and disease dynamics in these hosts...

BACKGROUND: The structure and function of bacterial nucleoid are controlled by histone-like proteins of HU/IHF family, omnipresent in bacteria and also founding archaea and some eukaryotes.HU protein binds dsDNA without sequence specificity and avidly binds DNA structures with propensity to be inclined such as forks, three/four-way junctions, nicks, overhangs and DNA bulges. Sequence comparison of thousands of known histone-like proteins from diverse bacteria phyla reveals relation between HU/IHF sequence, DNA-binding properties and other protein features...

Although Mycoplasma ovis (formerly Eperythrozoon ovis) has been described in small ruminants worldwide, data on M. ovis in goats remain scarce. Accordingly, the aims of the present study were to i) determine the prevalence of hemoplasmas in goats, ii) identify the tick species parasitizing the animals, and iii) determine factors associated with infection in five dairy and three beef goat farms from the Paraíba State, northeastern Brazil. Blood samples were obtained from 402 goats. Samples were screened for hemoplasmas using a pan-hemoplasma PCR...

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia-related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain...

Despite their small genomes mycoplasmas maintain large multigene families devoted to surface antigenic variation. Although implicated as important factors for mycoplasma pathogenicity and persistence, the role of these antigenic switches in host immune evasion has never been unequivocally proven in these minimalist microbes. Mycoplasma agalactiae exhibits antigenic variation due to Xer1-mediated site-specific DNA inversions of vpma genes encoding abundant multiple surface lipoproteins. To evaluate the biological significance of Vpma oscillations the xer1 recombinase gene has been disrupted in earlier studies to abolish Vpma switching and to generate stable phase-locked mutants (PLMs) steadily expressing a single Vpma product...

Multifocal serpiginoid choroiditis is an infectious variety of serpiginous choroiditis. The disease is characterized by infectious etiology and overlapping clinical features in an intermediary form of acute posterior multifocal placoid pigment epitheliopathy and serpiginous choroiditis. In a 33-year-old patient, bilateral multiple placoid partially confluent chorioretinal lesions were diagnosed after a febrile flu-like episode. On the right eye, there was a progressive decrease in visual acuity. Later, the lesions had a prolonged progressive devastating clinical course and widespread distribution of placoid lesions, and took the form of serpiginoid choroiditis...

Avian infectious bronchitis (IB) caused by the infectious bronchitis virus (IBV) and mycoplasmosis caused by Mycoplasma gallisepticum (MG) are two major respiratory diseases in chickens that have resulted in severe economic losses in the poultry industry. We constructed a recombinant adenovirus that simultaneously expresses the S1 spike glycoprotein of IBV and the TM-1 protein of MG (pBH-S1-TM-1-EGFP). For comparison, we constructed two recombinant adenoviruses (pBH-S1-EGFP and pBH-TM-1-EGFP) that express either the S1 spike glycoprotein or the TM-1 protein alone...

Introduction.Mycoplasma pneumoniae is a small cell-wall-lacking bacterium that belongs to the mycoplasma (Mollicutes) prokaryote micro-organisms. It is a common cause of both upper and lower respiratory tract infections in all age groups. Respiratory illness is the most common manifestation of M. pneumoniae infection; however, extrapulmonary involvement may be present or predominant. The skin, mucus membranes, central nervous system, cardiovascular system, haematopoietic system, kidneys and musculoskeletal system are the most commonly involved extrapulmonary sites...
