CDC Releases Recommendations for the Laboratory-Based Detection of Chlamydia trachomatis and Neisseria gonorrhoeae
An update on the 2002 CDC recommendations for screening of Chlamydia trachomatis and Neisseria gonorrhoeae infections. These recommendations discuss new recommendations for optimal specimen types, the use of tests to detect rectal and oropharyngeal C. trachomatis and N. gonorrhoeae infections, and the conditions in which supplemental testing is warranted.

Transportation of Specimens for Neisseria gonorrhoeae Culture
This APHL document describes the systems suitable for transporting N. gonorrhoeae specimens. It provides available performance data, and compares the benefits and limitations of each system.

The following helpful tables are from the Manual of Clinical Microbiology, 11th ed. (J. H. Jorgensen, M. A. Pfaller, K. C. Carroll, G. Funke, M. L. Landry, S. S. Richter and D. W. Warnock, ed.; ASM Press, Washington, DC, 2015), ASMscience

 Bacterial Collection, Transport and Storage Guidelines
Collection, transport, and storage guidelines for microbiological laboratory diagnostic studies.

 Interpretation of Bacterial Lower Respiratory Tract Culture Results 
Interpretative criteria used with respiratory tract specimens.

 Interpretation of Urine Culture Results
Interpretative criteria used with urine specimens.

 Recommendations for Gram Stain and Plating Media for Bacterial Specimens or Organisms
Gram stains can deliver rapid, actionable results to clinicians, can determine if a specimen is acceptable for culture based on cellularity, and should be used to aid the microbiologist in interpretation of the culture.

Bacterial Identification Tools

Practical Approach to the Identification of Glucose Non-Fermenting Gram-Negative Bacilli
Dr. Paul Schreckenberger’s Clinical Microbiology webpage and the home of the ASHEX Glucose Non-Fermenting Bacteria ID Database. This site was founded in 2004 to provide a home for their project, the ASHEX matrix, which utilizes a program called PIBWin to identify glucose non-fermenting bacteria with a set array of phenotypic tests.

Abbreviated Identification of Bacteria and Yeast, 2nd Edition
A CLSI document that provides the minimum identification criteria that can be used to rapidly identify organisms commonly isolated from clinical specimens. The FDA has evaluated and recognized this approved-level consensus guideline for use in satisfying a regulatory requirement.

Advanced Bacterial Identification Software (ABIS)
ABIS online is a laboratory tool for bacterial identification, based on morpho-biochemical characters, cultural characteristics, growth conditions, ecology  & pathogenicity data. The program allows a great flexibility in choosing biochemical tests and is an alternative to commercial systems, code-books or identification tables.The software is linked with a germs Encyclopedia, the Kauffman-White scheme for Salmonella serovars identification, and an antibiogram interpreter.Main identifiable taxons: Enterobacteriaceae, Pasteurellaceae, Bacillaceae, Campylobacter, Arcobacter,  Helicobacter, Lactobacillus, Staphylococcus, Streptococcus, Clostridium, Vibrio, Aeromonas, Pseudomonas and related species. More than 700 species are included in databases and more than 800 species in encyclopedia. 

Probabilistic Identification of Bacteria for Windows
The University of Southhampton's, United Kingdom, software program, PIBWin, provides probabilistic identification of unknown bacterial isolates against identification matrices of known strains. It has three major functions: the identification of an unknown isolate; the selection of additional tests to distinguish between possible strains if identification is not achieved; and the storage and retrieval of results.

NamesforLife Technology
Provides a completely new approach to bibliographic retrieval, based upon the use of nomenclature as a means of linking to content.

Taxonomy of Bacterial Species
LPSN is an up-to-date source for bacterial nomenclature and classification, listing all validly named species of bacteria, including those associated with animal and human infections.

Pediatric Pneumonia Guidelines
Guidelines on the diagnosis and treatment of community-acquired pneumonia (CAP) in infants and children, from the Pediatric Infectious Diseases Society (PIDS) and the Infectious Diseases Society of America (IDSA), emphasize the importance of immunizations, including a yearly influenza vaccine, to protect children from life-threatening pneumonia.

Vancomycin-Intermediate/Resistant Staphylococcus aureus Laboratory Testing Algorithm
All laboratories should develop a step-by-step problem-solving procedure or algorithm for detecting VISA/VRSA that is specific for their laboratory. A sample algorithm is available and highlights the recommended testing methodologies for detecting VISA/VRSA and actions based on results.

Detection of Enterobacteriaceae Isolates Carrying Metallo-Beta-Lactamase
During January--June 2010, three Enterobacteriaceae isolates carrying a newly described resistance mechanism, the New Delhi metallo-beta-lactamase (NDM-1) (1), were identified from three U.S. states at the CDC antimicrobial susceptibility laboratory. This is the first report of NDM-1 in the U.S., and the first report of metallo-beta-lactamase carriage among Enterobacteriaceae in the U.S.

Recommendation for Diagnosis of Shiga Toxin--Producing Escherichia coli Infection by Clinical Laboratories
Shiga toxin--producing Escherichia coli (STEC) This report provides comprehensive and detailed recommendations for STEC testing by clinical laboratories; detailed procedures for specimen selection, handling, and transport; a review of culture and nonculture tests for STEC detection; and clinical considerations and recommendations for management of patients with STEC infection.
