1/3. Highly resistant metabolically deficient dwarf mutant of escherichia coli is the cause of a chronic urinary tract infection.

    We present the case of a 68-year-old diabetic woman who has been suffering from chronic urinary tract infections, recurring over a period of at least 5 years, caused by a slowly growing metabolically deficient dwarf mutant (MDD) of escherichia coli. This MDD strain was auxotrophic for histidine, was resistant to multiple antibiotics, and showed atypical growth behavior. Colonies were tiny on routine media but were able to revert to normal growth after extended incubation. This strain was identified as E. coli by 16S ribosomal dna sequencing, and virulence factor profiles were determined by PCR. Seven MDD isolates collected over the 5-year period were grown from midstream urine to significant colony counts and shown to belong to the same clonal group by pulsed-field gel electrophoresis and enterobacterial repetitive intergenic consensus PCR. These MDDs were repeatedly misidentified by biochemical methods due to their slow growth and atypical colony morphology. This case highlights the importance of recognizing MDDs of enterobacteriaceae in patients with chronic infections. To our knowledge this is the first report of an MDD of E. coli causing a chronic urinary tract infection.

2/3. pregnancy complicated by emphysematous pyonephrosis.

    Emphysematous pyonephrosis is a rare, rapidly progressive infection characterized by the presence of exudative material and fermentative gases within a dilated renal collecting system. This unusual clinical entity is noted almost exclusively in diabetic patients, often in conjunction with chronic urinary tract infection and obstruction. In most instances, E. coli is the etiologic agent; however other enterobacteriaceae may be isolated. High fever, leukocytosis, renal parenchymal necrosis and the accumulation of gases in the kidney and perinephric tissues are the hallmark of this condition. Surgical resection of the involved tissue and systemic antibiotic administration are among the primary mainstays of therapy. We present a unique case of a pregnant patient with fulminant emphysematous pyonephrosis and the successful treatment rendered.

3/3. Neonatal enterobacter suppurative arthritis and osteomyelitis.

    Suppurative arthritis of the right knee and osteomyelitis of the adjacent femur complicated a urinary tract infection in an 18-day-old infant with a posterior urethral valve causing urinary flow obstruction. Initially cephalosporine sensitive Enterobacter caused the urinary tract infection. Shortly following cephazolin therapy, cephalosporine resistant Enterobacter microorganisms were isolated both from the urine and the knee joint fluid. These two infections were successfully treated with a combination of gentamicin and Co-trimoxazole. gram-negative bacteria should be considered among the pathogens in neonatal osteoarticular infections, particularly if a urinary tract infection co-exists.
