<prompt> Apart from Escherichia coli, the other most common organism implicated in acute suppurative bacterial peritonitis is-BacteroidesKlebsiellaPeptostreptococcusPseudomonas  <response>: When bacteria contaminate the peritoneum as a result of spillage from an intra-abdominal viscus. Infection in secondary bacterial peritonitis is polymicrobial E. coli and Bacteroides are MC organisms. The species of organism isolated vary with the source of the initial process and the normal flora present at the site. Peritonitis is one of the MC complications of CAPDQ, occurring with an incidence of approximately one episode every 1 to 3 years. Refractory or recurrent peritonitis is MC cause of technical failure of CAPD. MC organism: Staphylococcus epidermidis 3050.Clinical Features Patients present with abdominal pain, fever, and cloudy peritoneal dialysate containing 100 WBCmm3, with 50 of the cells being neutrophils. Gram staining detects organisms only in 1040 of cases.Treatment CAPD associated peritonitis is treated by the intraperitoneal administration of antibiotics, usually a first-generation cephalosporin. Overall, 75 of infections are cured by culture-directed antibiotic therapy. Recurrent or persistent peritonitis requires removal of the dialysis catheter and resumption of hemodialysis.
