Mycoplasma hominis and Ureaplasma urealyticum are common inhabitants of the human genital tract. Evidence for an aetiological role in pyelonephritis, pelvic inflammatory disease, post-abortion and post-partum fever has been presented. There are sporadic reports of Mycoplasma causing serious extragenital infection such as septicemia, septic arthritis, neonatal meningitis and encephalitis. We review 38 cases of surgical infections with Mycoplasma.

Pyomyositis is an infection of the striated muscle seen frequently in Africa but rarely in Western countries with a temperate climate. Over the last few years it has been observed with increasing frequency, especially in immunocompromised hosts. An unusual case of pyomyositis in a 65-year-old immunocompetent woman is described. The disease emerged during septicemia caused by Staphylococcus aureus. It was associated with pleuropneumonia and affected two different and opposite groups of muscles. Diabetes mellitus, a known predisposing factor, was diagnosed during the infection. The diagnosis of pyomyositis was based on microbiological cultures, computed tomography, and radio-labelled granulocyte scintigraphy. Follow-up until recovery was based on computed tomography. Surgical drainage of abscesses was avoided thanks to early diagnosis and specific antibiotic therapy.

A survey designed to obtain information on the indications, contraindications, complications, and methodology of percutaneous lung biopsy in the horse was sent to large animal diplomates of the American College of Veterinary Internal Medicine. Sixty-five of 190 diplomates returned the survey (response rate: 34%) and 59 of these 65 respondents (91%) indicated that they worked with horses. Forty-four diplomates had performed a percutaneous lung biopsy in 1 or more horses (i.e. 75% of those diplomates working with horses and 68% of total respondents). Clinical and radiologic diagnoses that prompted diplomates to perform percutaneous lung biopsy in the horse included a pulmonary miliary pattern (93%), suspicion of pulmonary infiltrative disease (91%), suspicion of pulmonary neoplasia (91%), suspicion of chronic obstructive pulmonary disease (COPD) (20%), and suspicion of exercise-induced pulmonary hemorrhage (EIPH) (7%). Only one of the respondents reported the use of percutaneous lung biopsy in the diagnostic workup if pneumonia was suspected, but 11% of respondents reported that suspicion of pulmonary abscessation would prompt them to perform a percutaneous lung biopsy. In contrast, a variable percentage of respondents felt there were contraindications to performance of this technique, which included neonatal septicemia (68%), pulmonary abscessation (65%), pleuropneumonia (55%) and pneumonia (42%), EIPH (41%), and COPD (26%). No respondent indicated that suspicion of neoplasia was a contraindication to percutaneous biopsy. Most common complications observed by respondents were epistaxis (68% of respondents), putative pulmonary hemorrhage (52%), tachypnea (39%), and respiratory distress (32%). Ten of 44 respondents (23%) had not seen any complications with percutaneous lung biopsy. Forty-two of 44 respondents (96%) warned owners about possible complications before performing percutaneous lung biopsy. All respondents to this question reported that they would perform percutaneous lung biopsies in horses in the future, but 4 of 41 would use the procedure only as a last resort.

Sickle cell disease is associated with frequent and often severe infections as a result of immune function impairment and functional asplenia. Also, infection can trigger a vasoocclusive crisis. Pneumococcal bacteremia and meningitis are so severe as to warrant prophylactic penicillin therapy, which has provided a dramatic decrease in early mortality. Bacterial pneumonia is common in patients younger than four years, with most cases being due to S. pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, and Chlamydia pneumoniae. Acute chest syndrome is both a difficult differential diagnosis and a common concomitant of bacterial pneumonia. Osteomyelitis is generally due to a salmonella, most often S. enteritidis; multiple foci are common and treatment is difficult, with some patients developing chronic osteomyelitis with sequestration. Parvovirus B 19 infection causes acute bone marrow failure. Malaria does not result in cerebral malaria but can lead to severe anemia or vasoocclusive crisis, and should therefore be effectively prevented. Antimicrobials are generally selected for efficacy against pneumococci (septicemia, meningitis), Salmonella (septicemia, meningitis, osteomyelitis), and mycoplasmas (pneumonia). Prophylactic therapy is of paramount importance and relies on long-term or lifelong penicillin therapy started at four months of age and on closely-spaced immunizations, most notably against pneumococci, the hepatitis B virus, S. typhi, and H. influenzae. Resistant pneumococcal strains have not been reported to cause prophylactic treatment failures. Conjugated pneumococcal vaccines are effective in protecting infants and should therefore be used in sickle cell patients.

Pericardial abscess is a very rare complication of sepsis. Authors describe the case of a 69-year-old woman. In her case staphylococcus sepsis led to pericardial abscess. During the course positive blood cultures (3x) indicated the sepsis and pus was obtained from the left pleural cavity (pleuropneumonia). Concomitant purulent process in the left shoulder also was noted. Decline immunity due to long-standing corticoid therapy (prednisone) for proctocolitis idiopathica was observed. Following antibiotic treatment successful surgical evacuation of the pericardial abscess was performed.

Severe CAP is a life-threatening condition defined by the presence of respiratory failure or symptoms of severe sepsis or septic shock. It accounts for approximately 10% of hospitalized patients with CAP. The majority of patients with severe pneumonia have underlying comorbid illnesses, with COPD, alcoholism, chronic heart disease, and diabetes mellitus being the most frequent. S. pneumoniae, Legionella spp, GNEB (especially K. pneumoniae), H. influenzae, S. aureus/spp, Mycoplasma pneumoniae, respiratory viruses (especially influenza viruses), and P. aeruginosa represent the most important causative organisms of severe CAP. Rapid initiation of appropriate antimicrobial treatment is crucial for a favorable outcome. Initial antimicrobial treatment should be based on an epidemiological (empiric) approach. Microbial investigation may be helpful in the individual case but is probably more useful to define local antimicrobial policies based on local epidemiologic and susceptibility patterns. Mortality rates range from 21% to 54%. The most important prognostic factors include general health state of the patient, appropriateness of initial antimicrobial treatment, and the existence of bacteremia, as well as factors reflecting severe respiratory failure, severe sepsis, septic hypotension or shock, and the extent of infiltrates in chest radiograph. Initial antimicrobial treatment should consist of a second (or third) generation cephalosporin and erythromycin. Modifications of this basic regimen should be considered in the presence of distinct comorbid conditions and risk factors for distinct pathogens. Promising new approaches of nonantimicrobial treatment, including noninvasive ventilation, treatment of hypoxemia, and immunomodulation, are under investigation.

We report a case of a retroperitoneal abscess due to Mycoplasma hominis in a young polytraumatized man who developed septicemia under treatment with rifampin and flucloxacillin. M. hominis was recovered from blood cultures as well as from the abscess near the left iliac spine. After 10 days of therapy with clindamycin the patient improved, and intraoperatively taken swabs were culture negative but still positive by PCR.

Four strains of Mycoplasma mycoides subsp. mycoides small colony type (MmmSC) isolated from recent outbreaks of contagious bovine pleuropneumonia (CBPP) in Africa have been investigated. One Botswanan strain, M375, displayed numerous and significant phenotypic differences from both contemporary field isolates and older field and vaccine strains (African, Australian, and European strains dating back to 1936). Differences include altered morphology, reduced capsular polysaccharide production, high sensitivity to MmmSC rabbit hyperimmune antisera in vitro, and unique polymorphisms following immunoblotting. While insertion sequence analysis using IS1634 clearly indicates a close evolutionary relationship to west African strains, hybridization with IS1296 shows the absence of a band present in all other strains of MmmSC examined. The data suggest that a deletion has occurred in strain M375, which may explain its altered phenotype, including poor growth in vitro and a relative inability to cause septicemia in mice. These characteristics are also exhibited by Mycoplasma capricolum subsp. capripneumoniae (causal agent of contagious caprine pleuropneumonia [CCPP]), against which M375 antiserum exhibited some activity in vitro (unique among the various MmmSC antisera tested). These findings may have evolutionary implications, since CCPP is believed to be lung specific and without a septicemic phase (unlike CBPP). Since M375 was isolated from a clinical case of CBPP, this novel biotype may be fairly widespread but not normally isolated due to difficulty of culture and/or a potentially altered disease syndrome. Bovine convalescent antisera (obtained from contemporary naturally infected cattle in Botswana) were active against strain M375 in an in vitro growth inhibition test but not against any other strains of MmmSC tested. There exists the possibility therefore, that strain M375 may possess a set of protective antigens different from those of other strains of MmmSC (including vaccine strains). These findings have implications for the control of the current CBPP epidemic in Africa.

We classified 1017 patients with community-acquired pneumonia requiring hospitalization experienced in Kawasaki Medical School Kawasaki Hospital during the past 15 years into five age groups (< or = 54 years old, 55-64 years old, 65-74 years old, 75-84 years old, > or = 85 years old). With particular emphasis on the elderly patients, we then compared the clinical and microbiological findings in the five groups. The results were as follows; (1) Half of patients in the over 85 years old group were bed-ridden. (2) The proportion receiving antibiotics before hospitalization decreased with age. (3) There were striking atypical pneumonic symptoms, such as dyspnea and consciousness disturbance in the two age groups over 75 years old. (4) Hypotension (shock) increased with age. (5) Markers of nutritional conditions, such as serum protein, albumin, cholinesterase, and hypoxia remarkably increased in the two age groups over 75 years old. (6) There were no significant differences in the isolation rate of etiological microorganisms. (7) The number of polymicrobial agents in the < or = 54 years old group was lower than that in the other age groups. (8) Mycoplasma pneumoniae was most significantly higher in < or = 54 years old group, Haemophilus influenzae in patients 55-64 years old, and Streptococcus pneumoniae in both 65-74 and 75-84 years old groups. (9) The isolation rate of MSSA, gram-negative bacilli such as Klebsiella pneumoniae, Pseudomonas aeruginosa, respiratory viruses increased with age. (10) The amount of sepsis increased with age. (11) The prognosis was poor in the two groups over 75 years old because the mortality rate (over 10%) was higher that for the other age groups.

The pathogenicity of the nondiphtheria corynebacteria, most commonly known as coryneform bacteria in humans has been recognized in the last two decades. Corynebacterium xerosis is part of the normal flora of the skin, nasopharynx, conjunctives and it has recently been isolated from vaginal swabs. During the last few years, there has been an increased number of case reports claiming an association of C. xerosis with diseases, like septicemia, endocarditis, pleuropneumonia, peritonitis, osteomyelitis, septic arthritis, mediastinitis, meningitis, ventriculitis specially in immunocompromised patients or surgical patients. Infections due to C. xerosis have been reported rarely in newborn. We report a case of sepsis due to C. xerosis in a newborn without evident immunodeficiency. Our case further support the recognition of C. xerosis as a human pathogen and reinforces the fact that it should not be routinely considered as a contaminant.
