Pseudomonas paucimobilis (formerly CDC group IIK, biotype 1) is a strictly aerobic, nonfermenting, oxidase- and catalase-positive, gram-negative bacillus that is widely distributed in water and soil. Its name derives from the difficulty encountered in demonstrating its motility, even in liquid media. This microorganism is responsible for two types of infection in humans: sporadic or community-acquired infections, probably of endogenous or environmental origin (bacteremia, meningitis, urinary tract infection, and wound infection); and outbreaks of nosocomial infection associated with the contamination of sterile fluids employed in hospitals. We present four cases of infection caused by P. paucimobilis (two of bacteremia, one of leg ulcer infection, and one of cervical adenitis). The majority of infections produced by P. paucimobilis have a good prognosis; no deaths related to this entity have been reported in the literature. The published results of susceptibility tests suggest that the aminoglycosides (either alone or in combination with a beta-lactam antibiotic) or the quinolone may be the agents of choice in the treatment of these infections.

The clinical manifestations of patients with group A beta-hemolytic streptococcal (GAS) bacteremia presenting to an urban children's hospital were reviewed. Group A beta-hemolytic streptococci were isolated from blood cultures from 17 children over a three-year period. Systemic illnesses that may have predisposed these children to GAS bacteremia were identified in seven patients: preceding varicella infection (four patients) or malignant neoplasm/immunosuppressive therapy (three patients). Possible sources of GAS included compromised integument (seven patients), the oropharynx (six patients), or the lower respiratory tract (two patients). The clinical manifestations of GAS sepsis included the following: fever (15 patients); arthritis or arthralgias (four patients); cellulitis (three patients); maculopapular eruption (one patient); petechial or pustular exanthems (three patients); osteomyelitis (two patients); cervical adenitis (one patient); empyema (one patient); and meningitis with multiple brain abscesses (one patient). Two patients died of apparent overwhelming GAS sepsis while at home. Group A beta-hemolytic streptococcal bacteremia can present with a wide range of clinical manifestations and cause mild to fulminant disease in children.

An increasing proportion of reported cases of toxic shock syndrom (TSS) are not associated with menstruation (13.2% of reported cases with onset in 1981). The 54 cases of TSS not associated with menstruation-reported through the US national surveillance system between January 1980-Jun 1981 were either associated with Staphylococcus aureus infections (cutaneous or subcutaneous lesions, infected surgical wounds, bursitis, mastitis, adenitis, lung abscess, or primary bacteremia) or followed childbirth be vaginal delivery and cesarean section. Patients with TSS not associated with menstruation differed significantly in age and racial distributions from those with menstruation-associated TSS, and 17 of them were male. The clinical features of TSS not associated with menstruation and the characteristics of the S. aureus strains isolated from these patients were similar to those observed in TSS related to menstruation. The median incubation period of the disease in postsurgical cases was 2 days. TSS can occur in many clinical settings in patients of both sexes and of all ages and races.

Seven infants with group B streptococcal (GBS) cellulitis-adenitis were compared with nine previously described patients. The clinical features of infection included a mean age at onset of five weeks, a male predominance (75%), a history of poor feeding or irritability (94%), and a rapid resolution with appropriate antimicrobial therapy. Bacteremia occurred in 94% of the patients. Type III GBS were associated with 75% of these infections; no antibody response to the capsular antigen of these organisms was detected in convalescent sera. Two of our cases had previously unreported sites of involvement, inguinal lymph nodes and a thyroglossal duct cyst. Four infants (80%) with typical facial or submandibular GBS cellulitis had ipsilateral otitis media at the time of admission. Otitis media with subsequent lymphatic spread to facial or submandibular areas, rather than primary bacteremia, may explain the pathogenesis of these unusual infections.

One hundred and thirty cases of toxic shock syndrome not associated with menstruation have been reported to the Centers for Disease Control, including 57 with onset in 1981 (12% of reported cases in 1981). These cases show that the syndrome occurs in a wide range of clinical settings and is associated with Staphylococcus aureus infections at a variety of sites: focal cutaneous and subcutaneous lesions, surgical-wound infections, postpartum infections, adenitis, bursitis, deep abscesses, and "primary" bacteremia. Although the clinical characteristics of nonmenstrual toxic shock syndrome are identical to those for menstrual toxic shock syndrome, the epidemiologic and demographic features are different. Of particular interest is the contrast in the racial distribution of the menstrual and nonmenstrual cases. Toxic shock syndrome can occur in persons of any age, race, or sex and must be considered in the differential diagnosis for any patient with a compatible illness.

Three hundred eighty-six isolates of Propionibacterium sp. were recovered from 2,003 specimens studied for the identification of anaerobic bacteria in children during a 15-year period. Three hundred forty-three (89%) of these were Propionibacterium acnes. A total of 50 (13%) Propionibacterium isolates identified from 45 patients were considered to cause infection. Clinically significant infections caused by Propionibacterium sp. were associated with bacteremia in 10 children; ear infection in eight; abscesses in seven; adenitis and central nervous system infection in five each; burns in four; wounds in three; tumors and bone in two each; and cysts, eye, sinus, and mastoid in one each. Predisposing or underlying conditions were present in 33 children (73%). These included the presence of a foreign body (17), immunodeficiency (six), malignancy (five), diabetes (five), previous surgery (four), and steroid therapy (two). Antimicrobial therapy was given to 41 (91%) children. Surgical drainage was concomitantly performed in 22 (49%). Four patients died. This study highlights the importance of Propionibacterium sp. as an unusual, but potentially important, pathogen in children.

Bartonella (Rochalimaea) henselae causes a variety of diseases, including bacillary angiomatosis, peliosis hepatis, lymphadenitis, aseptic meningitis with bacteremia, and cat-scratch disease (CSD). Cases of B. henselae-related disease were collected from September 1991 through November 1993. Patients with suspected CSD, unexplained fever and lymphadenitis, or suspected B. henselae infection who were seen in the Infectious Diseases Clinic at Wilford Hall Medical Center (Lackland Air Force Base, TX) underwent physical and laboratory examinations. In addition to three previously described cases, 23 patients with R. henselae-related infection were identified. The patients included 19 immunocompetent individuals presenting with lymphadenitis (11), stellate neuroretinitis (5), Parinaud's oculoglandular syndrome with retinitis (1), chronic fatigue syndrome-like disease (1), and microbiologically proven adenitis without the presence of immunofluorescent antibodies to B. henselae (1) and four patients infected with human immunodeficiency virus type 1 presenting with isolated lymphadenitis (1), diffuse upper-extremity adenitis (1), neuroretinitis (1), and aseptic meningitis (1). A couple with neuroretinitis and their pet cat, a persistently fatigued patient, and a patient with Parinaud's oculoglandular syndrome were shown to have bacteremia. Tissue cultures were positive for B. henselae in three recent cases of adenitis. Twenty-two patients were exposed to cats. This series further demonstrates the similarities between B. henselae-related diseases and CSD and identifies several new syndromes due to B. henselae.

Burkholderia gladioli has only recently been reported to be a human pathogen. Four cases of B. gladioli infection (including bacteremia, pneumonia, and cervical adenitis) in two adults and two young children are reported. Three of these four patients were severely immunocompromised. Commercial systems were frequently unable to identify this bacterium correctly. Antimicrobial susceptibility patterns indicated that B. gladioli strains were susceptible to the quinolones, aminoglycosides, and imipenem. In vitro laboratory investigations demonstrated that B. gladioli strains were susceptible to complement-mediated lysis of pooled human serum, thus implying that healthy individuals should be immune to infection. These four cases together with three previously reported cases suggest that B. gladioli primarily causes disease in severely immunocompromised individuals. The lack of mortality associated with infection, coupled with susceptibility to serum and lack of recognizable virulence-associated factors, suggests that this species has a low pathogenic potential.

A registry of United States residents with chronic granulomatous disease (CGD) was established in 1993 in order to estimate the minimum incidence of this uncommon primary immunodeficiency disease and characterize its epidemiologic and clinical features. To date, 368 patients have been registered; 259 have the X-linked recessive form of CGD, 81 have 1 of the autosomal recessive forms, and in 28 the mode of inheritance is unknown. The minimum estimate of birth rate is between 1/200,000 and 1/250,000 live births for the period 1980-1989. Pneumonia was the most prevalent infection (79% of patients; Aspergillus most prevalent cause), followed by suppurative adenitis (53% of patients; Staphylococcus most prevalent cause), subcutaneous abscess (42% of patients; Staphylococcus most prevalent cause), liver abscess (27% of patients; Staphylococcus most prevalent cause), osteomyelitis (25% of patients; Serratia most prevalent cause), and sepsis (18% of patients; Salmonella most prevalent cause). Fifteen percent of patients had gastric outlet obstruction, 10% urinary tract obstruction, and 17% colitis/enteritis. Ten percent of X-linked recessive kindreds and 3% of autosomal recessive kindreds had family members with lupus. Eighteen percent of patients either were deceased when registered or died after being registered. The most common causes of death were pneumonia and/or sepsis due to Aspergillus (23 patients) or Burkholderia cepacia (12 patients). Patients with the X-linked recessive form of the disease appear to have a more serious clinical phenotype than patients with the autosomal recessive forms of the disease, based on the fact that they are diagnosed significantly earlier (mean, 3.01 years of age versus 7.81 years of age, respectively), have a significantly higher prevalence of perirectal abscess (17% versus 7%), suppurative adenitis (59% versus 32%), bacteremia/fungemia (21% versus 10%), gastric obstruction (19% versus 5%), and urinary tract obstruction (11% versus 3%), and a higher mortality (21.2% versus 8.6%).
