background: resistance to contemporary broad-spectrum b-lactam antibiotics mediated by extended-spectrum b-lactamases (esbls) is increasing worldwide. klebsiella pneumoniae , an important cause of nosocomial and community acquired urinary tract infections has rapidly become the most common esbl producing organism. we examined esbl production in urinary isolates of k. pneumoniae in relation to t...

Mycoplasma pneumoniae is a leading cause of community-acquired pneumonia. Although two genetically distinct types of M. pneumoniae are known, variants of each also exist. We used a real-time PCR high-resolution melt genotyping assay to identify clinical variants which may provide greater insight into the genetic distribution of M. pneumoniae strains.

The present study evaluated the association between different Mycoplasma pneumoniae (M. pneumonia) genotypes and clinical features of pediatric patients. Subjects were children diagnosed with community-acquired pneumonia at the Children's Hospital of Soochow University (Suzhou, China) from January 2012 to December 2013. Clinical and laboratory tests were conducted and clinical samples positive ...

The most common clinical signs, host responses and radiographic patterns were studied in 203 Italian children hospitalized for community-acquired pneumonia in order to clarify the role of clinical and radiological characteristics in the diagnosis of Mycoplasma pneumoniae and/or Chlamydia pneumoniae infections. Antibody measurements in paired sera and polymerase chain reaction on nasopharyngeal ...

Mycoplasma pneumoniae is responsible for approximately 20% to 30% of community-acquired pneumonia, and is well known for its diverse extrapulmonary manifestations. However, acute necrotizing pancreatits is an extremely rare extrapulmonary manifestation of M. pneumoniae infection. A 6-year-old girl was admitted due to abdominal pain, vomiting, fever, and confused mentality. Acute necrotizing pan...

The polymerase chain reaction (PCR) technique was used to detect Mycoplasma pneumoniae. A specific DNA sequence for M. pneumoniae was selected from a genomic library, and two oligonucleotides were chosen in this sequence to give an amplified fragment of 144 base pairs. We show that DNA from different M. pneumoniae strains can be detected by PCR, with DNA from other Mycoplasma species giving neg...

Serology remains the method of choice for laboratory diagnosis of Mycoplasma pneumoniae infection. Currently available serological tests employ complex cellular fractions of M. pneumoniae as antigen. To improve the specificity of M. pneumoniae diagnosis, a recombinant protein was assessed as a serodiagnostic reagent. A panel of recombinant proteins were expressed from a cloned M. pneumoniae gen...

STUDY OBJECTIVE This study was designed to evaluate the usefulness of polymerase chain reaction (PCR) to detect Mycoplasma pneumoniae DNA in samples obtained by transthoracic needle aspiration (TNA). DESIGN Prospective study of cases. SETTING A university hospital in Lleida, Spain. PATIENTS A total of 101 unselected patients, admitted between January 1993 and March 1994 in the emergency d...

Historically, atypical pneumonia was a term used to describe an unusual presentation of pneumonia. Currently, it is used to describe the multitude of symptoms juxtaposing the classic symptoms found in cases of pneumococcal pneumonia. Specifically, atypical pneumonia is a syndrome resulting from a relatively common group of pathogens including Chlamydophila sp., and Mycoplasma pneumoniae. The in...

We describe a case of rhabdomyolysis in a patient infected with antimicrobial drug-resistant Mycoplasma pneumoniae The patient's acute-phase serum levels of interleukin-18 and tumor necrosis factor-α were high, which suggests a pathogenic role for M. pneumoniae. In an era of increasing antimicrobial drug resistance, a system for rapidly identifying resistant M. pneumoniae would be beneficial.
