  • Streptococci
    STREPTOCOCCI Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Older cultures may lose their Gram-positive character. Most streptococci are facultative anaerobes, and some are obligate (strict) anaerobes. Most require enriched media (blood agar). Streptococci are subdivided into groups by antibodies that recognize surface antigens (Fig. 11). These groups may include one or more species. Serologic grouping is based on antigenic differences in cell wall carbohydrates (groups A to V), in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. Rebecca Lancefield developed the serologic classification scheme in 1933. β-hemolytic strains possess group-specific cell wall antigens, most of which are carbohydrates. These antigens can be detected by immunologic assays and have been useful for the rapid identification of some important streptococcal pathogens. The most important groupable streptococci are A, B and D. Among the groupable streptococci, infectious disease (particularly pharyngitis) is caused by group A. Group A streptococci have a hyaluronic acid capsule. Streptococcus pneumoniae (a major cause of human pneumonia) and Streptococcus mutans and other so-called viridans streptococci (among the causes of dental caries) do not possess group antigen. Streptococcus pneumoniae has a polysaccharide capsule that acts as a virulence factor for the organism; more than 90 different serotypes are known, and these types differ in virulence. Fig. 1 Streptococci - clasiffication. Group A streptococci causes: Strep throat - a sore, red throat, sometimes with white spots on the tonsils Scarlet fever - an illness that follows strep throat. It causes a red rash on the body.

  • Pneumococcal Disease (Sickness Caused by Streptococcus Pneumoniae)
    Pneumococcal Disease (Sickness Caused by Streptococcus pneumoniae) What is pneumococcal disease? Pneumococcal disease is an infection caused by the bacteria Streptococcus pneumoniae. It's also called pneumococcus and can cause ear infections, pneumonia, infections in the blood and meningitis. When does it happen? Children can get pneumococcal disease any time of the year. What are the symptoms? Fever and increased fussiness or irritability are common Meningitis symptoms include fever, trouble bending or moving the neck, increased fussiness or irritability, and headache in anyone over age 2. In babies, the only symptoms may be that the baby is less active, fussy or crying more than usual, throwing up, or not eating normally. Pneumonia symptoms in children include fever, cough, working hard to breathe, breathing faster than usual or grunting. Ear infection symptoms are ears that hurt, crying or pulling on ears, sore throat or pain when swallowing. Children may also be sleepy, have a fever, and be fussy. Is it contagious? How is it spread? Pneumococcus is spread by contact with people who either have a pneumococcal illness or who carry the bacteria in their throats without being sick. It can be spread by droplets in the air from coughing or sneezing. It can also be spread if you touch something that has the droplets on it, and then touch your own nose, mouth or eyes. How bad is pneumococcal disease? Pneumococcal disease can be very bad for young children and is the most common cause of meningitis and bacterial pneumonia in children. How can pneumococcal disease be avoided in children? There is a vaccine that can help stop serious pneumococcal disease, such as meningitis and blood infections.

Lacks* Biology Department Brookhaven National Laboratory Upton, NY 11973 Phone: 631-344-3369 Fax: 631-344-3407 E-mail: [email protected] Introduction Transformation, which alters the genetic makeup of an individual, is a concept that intrigues the human imagination. In Streptococcus pneumoniae such transformation was first demonstrated. Perhaps our fascination with genetics derived from our ancestors observing their own progeny, with its retention and assortment of parental traits, but such interest must have been accelerated after the dawn of agriculture. It was in pea plants that Gregor Mendel in the late 1800s examined inherited traits and found them to be determined by physical elements, or genes, passed from parents to progeny. In our day, the material basis of these genetic determinants was revealed to be DNA by the lowly bacteria, in particular, the pneumococcus. For this species, transformation by free DNA is a sexual process that enables cells to sport new combinations of genes and traits. Genetic transformation of the type found in S. pneumoniae occurs naturally in many species of bacteria (70), but, initially only a few other transformable species were found, namely, Haemophilus influenzae, Neisseria meningitides, Neisseria gonorrheae, and Bacillus subtilis (96). Natural transformation, which requires a set of genes evolved for the purpose, contrasts with artificial transformation, which is accomplished by shocking cells either electrically, as in electroporation, or by ionic and temperature shifts. Although such artificial treatments can introduce very small amounts of DNA into virtually any type of cell, the amounts introduced by natural transformation are a million-fold greater, and S.

High genetic and taxonomic similarities and several reclassifications within genera are the most challenging in species identification. The aim of this study was to identify Streptococcus and Enterococcus species using genetic and phenotypic methods and to determine the most discriminatory identification method. Thirty strains recovered from clinical samples representing 15 streptococcal species, five enterococcal species, and four nonstreptococcal species were subjected to bacterial identification by the Vitek® 2 system and Sanger-based sequencing methods targeting the 16S rRNA, sodA, tuf, rpoB, and recA genes. Phenotypic methods allowed the identification of 10 streptococcal strains, five enterococcal strains, and four nonstreptococcal strains (Leuconostoc, Granulicatella, and Globicatella genera). The combination of sequencing methods allowed the identification of 21 streptococcal strains, five enterococcal strains, and four nonstreptococcal strains.

  • Pneumonia Panel
    Guidance on Use of the Pneumonia Panel for Respiratory Infections Although the number of pathogens that cause pneumonia is lengthy, establishing the microbiologic etiology of pneumonia is inherently difficult. A recent large multi-center study of community-acquired pneumonia (CAP) found that only 38% of 2259 CAP cases had a microbiologic diagnosis with 23% having viruses detected, 11% bacterial, and 3% had both viruses and bacteria detected.1 Current tools to assist in pneumonia diagnosis include respiratory tract cultures (sputum, BAL, tracheal aspirate, mini-BAL), urine antigens (pneumococcal, Legionella), serology, and PCR for viral and certain bacterial pathogens. While these tools are useful, the study noted above used all these tools and was unable to document an etiology causing pneumonia in 62% of patients. Thus, more sensitive tools for detection of respiratory pathogens are still needed. Nebraska Medicine has recently introduced a new FDA-approved multiplex PCR panel to assist in determination of the etiology of pneumonia, termed the Pneumonia Panel (PP). This test uses a nested multiplex PCR- approach to amplify nucleic acid targets directly from sputum or bronchoalveolar lavage (BAL) in patients with suspected pneumonia. The list of pathogens and resistance genes included in the panel is found in Table 1. Note that the bacterial targets are detected semi-quantitatively whereas the atypical pathogens and the viral targets are detected qualitatively. Table 1: Pneumonia Panel Pathogen Targets and Associated Resistance Genes Semi-quantitative Detection: Gram Positive Organisms: Resistance Genes (Staph aureus only): Staphylococcus aureus mecA/C and MREJ Streptococcus pneumoniae Streptococcus agalactiae Streptococcus pyogenes Gram Negative Organisms: Resistance Genes (All Gram Negatives): Acinetobacter calcoaceticus-baumannii complex CTX-M Enterobacter cloacae complex IMP E.
