Species and biotypes of Streptococcus bovis causing infective endocarditis.

Introduction: Streptococcus bovis/equinus complex (SBEC) is a major cause of infective endocarditis (IE), although its incidence varies greatly depending on the geographical area. The characteristics of IE caused by Streptococcus gallolyticus susp. gallolyticus are well known; there are hardly any descriptions of IE caused by other species or biotypes.

Relationship among Subsp. , and Colorectal Neoplasms in Recurrent Endocarditis: A Historical Case Series.

Objectives: The role of colorectal neoplasms (CRN) as a common potential source of recurrent subsp. (SGG) and (EF) endocarditis remains unstudied. We aimed to investigate what proportion of episodes of recurrent endocarditis are caused by a succession of SGG and EF, or vice versa, and to assess the role of a colonic source in such recurrent episodes.

Methods: This is a multicenter, comparative study of patients with CS bacteremia [44 of 664 cases (6.

Streptococcus bovis septic arthritis and osteomyelitis: A report of 21 cases and a literature review.

Background: The Streptococcus bovis group (SBG) is a well-known cause of endocarditis, but its role in osteoarticular infections (OAIs) has not been well described.

Methods: We analyzed all patients with OAIs by SBG diagnosed in our hospital (1988-2014). We selected those cases with septic arthritis and osteomyelitis, as defined according to clinical, microbiological, and imaging studies.

[Microbiological diagnosis of bacterial infection associated with delivery and postpartum].

The newborn may acquire infections during delivery due to maternal colonization of the birth canal, by microorganisms such as Streptococcus agalactiae that caused early neonatal infection, or acquisition through the placenta, amniotic fluid or birth products. After birth, the newborn that needs hospitalization can develop nosocomial infections during their care and exceptionally through lactation by infectious mastitis or incorrect handling of human milk, which does not require to stop breastfeeding in most cases. It is important and necessary to perform microbiological diagnosis for the correct treatment of perinatal infections, especially relevant in preterm infants with low or very low weight with high mortality rates.

Differences between endocarditis caused by Streptococcus bovis and Enterococcus spp. and their association with colorectal cancer.

Streptococcus bovis group and Enterococcus spp. share phenotypic characteristics and intestinal habitat. Both have been associated with endocarditis and colorectal neoplasm (CRN).

The clinical epidemiology and malignancies associated with Streptococcus bovis biotypes in 506 cases of bloodstream infections.

Objectives: To determine the incidence of Streptococcus bovis (Sb) biotypes causing bacteraemia and associated malignancies.

Methods: This is a retrospective analysis of patients with Sb bacteraemia, pulled out from a prospective surveillance protocol of bacteraemia cases, in three areas of Spain (1990-2013): a cattle area (Lugo), a fishing area (Ferrol) and an urban area (Barcelona). Colonoscopy and Sb biotypes (Sb-I and Sb-II) were determined in most cases.

Molecular epidemiology and virulence of Escherichia coli O16:H5-ST131: comparison with H30 and H30-Rx subclones of O25b:H4-ST131.

The present study was carried out to evaluate the prevalence of the clonal subgroup O16:H5-ST131 and the H30 and H30-Rx subclones among E. coli isolates causing extraintestinal infections and to know their virulence potential. The ST131 clonal group accounted for 490 (16%) of the 2995 isolates obtained from clinical samples in five Spanish hospitals during the study period (2005-2012).

Is Streptococcus bovis a urinary pathogen?

The Streptococcus bovis group (SBG) comprises several microorganisms associated with human infections. They have been associated with bacteremia, endocarditis, biliary tract infection, meningitis, and colorectal cancer, but their role as urinary pathogens is not well known. The objective of this investigation was to discover the incidence and clinical significance of the bacteriuria associated with this complex.

Streptococcus bovis group and biliary tract infections: an analysis of 51 cases.

Streptococcus bovis is a well-known cause of endocarditis, but its role in other infections has not been well described. We analysed prospectively all patients with biliary tract infections caused by S. bovis group during the period 1988-2011.

Poultry as reservoir for extraintestinal pathogenic Escherichia coli O45:K1:H7-B2-ST95 in humans.

Escherichia coli strains O45:K1:H7 are implicated in severe human infections such as meningitis. Since an increasing prevalence of serogroup O45 among avian pathogenic (APEC) and human extraintestinal pathogenic (ExPEC) E. coli strains isolated in Spain have been noticed, the aims of the present study were to investigate similarities between poultry and human O45 isolates, and to investigate the evolutionary relationship of ST95 types.

Objectives: Methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the mecC gene have been reported from humans and animals from several European countries, but never from Spain. We describe the first isolates of mecC-positive MRSA of human origin collected in Spain and report a fatal case of bacteraemia.

Methods: Isolates were tested for phenotypic resistance using cefoxitin, tested for the mecA/mecC genes and toxin genes by PCR, and typed by staphylococcal cassette chromosome mec (SCCmec), PFGE, spa, multilocus sequence typing and agr.

Is colonoscopy necessary in cases of infection by Streptococcus bovis biotype II?

The association of colorectal neoplasia (CRN) with Streptococcus bovis biotype I (SBI) infection is well recognized. However, this is not the case for Streptococcus bovis biotype II (SBII). We conducted this study in order to analyze the relationship between SBII and CRN.

Association between bacteremia due to Streptococcus gallolyticus subsp. gallolyticus (Streptococcus bovis I) and colorectal neoplasia: a case-control study.

Background: The association between bacteremia by Streptococcus gallolyticus subsp. gallolyticus (SGG) and colorectal neoplasia (CRN) is well established but the frequency of the association varies widely in different studies. We conducted a case-control study to assess the association between SGG bacteremia and CRN.

[Microbiological diagnosis of intra-abdominal infections].

Intra-abdominal infections represent a large and wide group of diseases which include intra- and retro-peritoneal infections. Some of them could be defined as uncomplicated, where the infectious process is limited to the organ or tissue of origin (appendicitis, diverticulitis, cholecystitis…). Complications occur when the infection spreads to the peritoneum, triggering localised peritonitis and abdominal abscesses.
