A simple mathematical model to determine the ideal empirical antibiotic therapy for bacteremic patients BJID
Tuon,Felipe F.; Rocha,Jaime L.; Leite,Talita M.; Dias,Camila.
BACKGROUND: Local epidemiological data are always helpful when choosing the best antibiotic regimen, but it is more complex than it seems as it may require the analysis of multiple combinations. The aim of this study was to demonstrate a simplified mathematical calculation to determine the most appropriate antibiotic combination in a scenario where monotherapy is doomed to failure. METHODS: The susceptibility pattern of 11 antibiotics from 216 positive blood cultures from January 2012 to January 2013 was analyzed based on local policy. The length of hospitalization before bacteremia and the unit (ward or intensive care unit) were the analyzed variables. Bacteremia was classified as early, intermediate or late. The antibiotics were combined according to the...

A single center 14 years study of infectious complications leading to hospitalization of patients with primary antibody deficiencies BJID
Mamishi,Setareh; Eghbali,Aiden Nasiri; Rezaei,Nima; Abolhassani,Hassan; Parvaneh,Nima; Aghamohammadi,Asghar.
Primary antibody deficiencies (PADs) are a heterogeneous group of disorders, characterized by hypogammaglobulinemia and increased susceptibility to bacterial infections, leading to hospitalizations. This study was performed to determine the main infectious causes of hospital admissions in selective Iranian patients with PADs. Forty patients with PADs, who were admitted to the Infectious Ward of Children's Medical Center Hospital during a 14-year period, were reviewed in this study. There were 115 documented episodes of hospital admission during a 14-year period. The average length of hospital stay was 33.30 ± 25.72 days. Pneumonia was the most prominent infection leading to hospitalization among these patients (n = 48), followed by gastroenteritis (n =...

Adhesion of uredospores of Phakopsora pachyrhizi on soybean seeds and their viability during storage Rev. bras. sementes
Magnani,Elisandra Batista Zambenedetti; Mendonça,Elisabeth Aparecida Furtado de; Albuquerque,Maria Cristina de Figueiredo e.
To study adhesion and viability of uredospores of the fungus Phakopsora pachyrhizi on soybean seeds during storage, suspension tests of those uredospores were carried out by washing seeds at each 30 days interval. Furthermore, germination and inoculation tests of uredospores on soybean plants were performed with uredospores collected from seeds of two soybean production areas, located in the municipalities "Chapada dos Guimarães" and "Tangará da Serra", State of Mato Grosso, Brazil. High levels of uredospores infestation were detected before storage [249.31 and 85.18 uredospores/100 seeds (U/100)] on seeds collected in both localities, respectively. After 30 days storage, these figures were 46.12 and 122.5 U/100; at 60 days were 14.62 and 26.62 U/100; and...

Altered peripheral lymphocyte subsets in untreated systemic lupus erythematosus patients with infections BJMBR
Lu,Zhimin; Li,Jing; Ji,Juan; Gu,Zhifeng; Da,Zhanyun.
The leading cause of death in systemic lupus erythematosus (SLE) patients is infection. The objective of this study was to evaluate the distribution of lymphocyte subsets in untreated SLE patients with infections. This was a cross-sectional study. Data from January 2017 to May 2018 were collected. Flow cytometry was used to measure the peripheral lymphocyte subsets including CD3+T cells, CD4+T cells, CD8+T cells, CD19+B cells, CD3-CD16+CD56NK cells, and CD3+CD16+CD56NKT cells in 25 healthy controls and 52 treatment-naive SLE patients, among whom 13 were complicated with infections. Association between the lymphocyte subsets and infections was further analyzed. SLE patients with infections (n=13) showed a significantly higher incidence rate of fever (84.6...

Anti-Bacterial Activity of Phenolic Compounds against Streptococcus pyogenes ArchiMer
Macé, Sabrina; Truelstrup Hansen, Lisbeth; Rupasinghe, H. P. Vasantha.
Background: Worldwide, Streptococcus pyogenes is the leading cause of bacterial pharyngitis. To reduce the use of antibiotics, antimicrobial phytochemical-containing remedies, which have long been in use in traditional medicine, may provide new approaches for management of streptococcal pharyngitis. The objective of this study was to assess the inhibitory activities of 25 natural phenolic compounds against three strains of S. pyogenes. Methods: After an initial screening, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the nine most effective phenolic compounds were determined. The effect of four compounds with the lowest MIC and MBC on streptococcal growth and biofilm formation was also studied. Results:...

Antibiotics produced by Streptomyces BJID
Procópio,Rudi Emerson de Lima; Silva,Ingrid Reis da; Martins,Mayra Kassawara; Azevedo,João Lúcio de; Araújo,Janete Magali de.
Streptomyces is a genus of Gram-positive bacteria that grows in various environments, and its shape resembles filamentous fungi. The morphological differentiation of Streptomyces involves the formation of a layer of hyphae that can differentiate into a chain of spores. The most interesting property of Streptomyces is the ability to produce bioactive secondary metabolites, such as antifungals, antivirals, antitumorals, anti-hypertensives, immunosuppressants, and especially antibiotics. The production of most antibiotics is species specific, and these secondary metabolites are important for Streptomyces species in order to compete with other microorganisms that come in contact, even within the same genre. Despite the success of the discovery of antibiotics,...

B-1 cell: the precursor of a novel mononuclear phagocyte with immuno-regulatory properties Anais da ABC (AABC)
Lopes,José Daniel; Mariano,Mario.
Characterization of the origin, properties, functions and fate of cells is a fundamental task for the understanding of physiological and pathological phenomena. Despite the bulk of knowledge concerning the diverse characteristics of mammalian cells, some of them, such as B-1 cells, are still poorly understood. Here we report the results obtained in our laboratory on these cells in the last 10 years. After showing that B-1 cells could be cultured and amplified in vitro, a series of experiments were performed with these cells. They showed that B1 cells reside mostly in the peritoneal and pleural cavities, migrate to distant inflammatory foci, coalesce to form giant cells and participate in granuloma formation, both in vitro and in vivo. They are also able to...

Bacterial biofilms with emphasis on coagulase-negative staphylococci J. Venom. Anim. Toxins incl. Trop. Dis.
Oliveira,A; Cunha,MLRS.
In addition to their capacity to attach to surfaces, various groups of microorganisms also produce an extracellular polymeric substance known as "slime". This slime forms a thin layer around cells known as biofilm. Thus, biofilm structure comprises bacterial cells and an extracellular polymeric substance. It also presents a defined architecture, providing the microorganisms with an excellent protective environment and favoring the exchange of genetic material between cells as well as intercellular communication. The ability to produce biofilm is observed in a large group of bacteria, including coagulase-negative staphylococci (CNS) which are the predominant microorganisms of normal skin flora and have been implicated as the causative agents of hospital...

Bonamia ostreae, parasite of the European flat oyster, Ostrea edulis, does not experimentally infect the Japanese oyster, Crassostrea gigas ArchiMer
Renault, Tristan; Cochennec, Nathalie; Grizel, Henri.
The protozoan Bonamia ostreae (Ascetospora) is the etiological agent of bonamiosis, or hemocyte disease of the European fiat oyster, Ostrea edulis (Pichot et al., 1980). Since this infection was first reported from the coast of Brittany (Comps et al., 1980), the parasite has spread rapidly along the French Atlantic coasts (Grizel & Tigé, 1982), and in the European countries including the UK, Holland, lreland and Spain (Bannister & Key, 1982; Van Banning, 1982; Polanco et al., 1984). Under the EEC Council Directive 91/67, this parasitic protozoan is included in list II of Annex A. Serious pathogen agents for molluscs that should be obligatorily declared are placed in this list

Chronic granulomatous disease: why an inflammatory disease? BJMBR
Roxo-Junior,P.; Simão,H.M.L..
Chronic granulomatous disease is a primary immunodeficiency caused by mutations in the genes encoding subunits of the phagocytic NADPH oxidase system. Patients can present with severe, recurrent infections and noninfectious conditions. Among the latter, inflammatory manifestations are predominant, especially granulomas and colitis. In this article, we systematically review the possible mechanisms of hyperinflammation in this rare primary immunodeficiency condition and their correlations with clinical aspects.

Clustering of Enterococcus faecalis infections in a cardiology hospital neonatal intensive care unit BJID
Strabelli,Tânia Mara Varejão; Cais,Daiane P.; Zeigler,Rogério; Siciliano,Rinaldo; Rodrigues,Cristhieni; Carrara,Dirceu; Neres,Suzi; Lessa,Sarita; Uip,David Everson.
Early identification of an outbreak is one of the main advantages of routine epidemiological surveillance. Enterococcus spp. used to be regarded as microorganisms of low pathogenicity, because they are part of the normal microbial flora of the gastrointestinal and genitourinary tract. Recently, they have emerged as important pathogenic agents, sometimes causing infections with high mortality rates. We studied a clustering of primary bloodstream infections caused by Enterococcus faecalis in a cardiology hospital neonatal intensive care unit (NICU). Four cases of primary bloodstream infection by E. faecalis were detected from April 15 to May 13, 2004, during active infection surveillance. The isolates were sensitive to glycopeptides. Some aspects of the...
