Enterococci are important causes of community-acquired and nosocomial infection. They cause endocarditis, bacteremia, urinary tract infections and neonatal sepsis. As causes of intra-abdominal and pelvic infection, enterococci are more commonly associated with abscess, biliary tract infection, spontaneous bacterial peritonitis, post-operative infection, post-partum endomyometritis and chronic or recurrent infection. As causes of soft tissue infection, enterococci are more commonly identified in burns, decubitus or diabetic foot ulcers, and wounds associated with intestinal surgery. Enterococci are often cultured in association with other pathogens when identified in intra-abdominal, pelvic or skin and soft tissue infection. Enterococcal superinfection after therapy with cephalosporins has been well described, and occurs as a result of the low in vitro activity of cephalosporins against enterococci. The epidemiology of enterococcal infection is complex and includes both endogenous and exogenous acquisition of the organism. Antibiotic resistance is an ever-increasing problem complicating therapy in patients with enterococcal infection.

Bacterial infection is a serious and often fatal complication of patients with liver disease and can prove fatal either directly or by precipitation of gastrointestinal bleeding, renal failure, or hepatic encephalopathy. At greatest risk are patients with alcoholic cirrhosis or decompensated chronic liver disease, or cases of acute liver disease who progress to fulminant hepatic failure or subacute hepatic necrosis. Infection appears to be unusual in patients with primary biliary cirrhosis. The site and type of infection is unrelated to the aetiology of the liver disease. Bacteraemia, pneumonia, urinary tract infection and spontaneous bacterial peritonitis are most common but infective endocarditis and meningitis, especially with pneumococci, are easily overlooked. Clinical suspicion of infection must be high as the only indication may be a general deterioration in the patients' clinical state, increasing encephalopathy or renal impairment. In the case of patients with fulminant hepatic failure, infection may precipitate the initial or recurrent encephalopathy and contributes to death in 10% of fatal cases. Spontaneous bacterial peritonitis is now recognized to occur in the absence of clinical features of peritonitis. The PMN content of the ascitic fluid may provide the only indication of infection and is the most readily available screening test. The most common types of organism responsible for all types of infection are Gram-negative enteric and streptococci, especially pneumococci, while infection with anaerobes is rare. Risk factors for infection include decompensated alcoholic liver disease, fulminant hepatic failure, gastrointestinal bleeding, invasive practical procedures and impaired host defence mechanisms against infection. Of the host defence mechanisms, impaired function of the reticuloendothelial system, complement, and PMNs represent the most common and serious defects. Defects of humoral immunity are present in ascitic fluid from patients with cirrhosis and are probably a major reason for development of spontaneous bacterial peritonitis. Diuresis improves these functions and reduces the risk of peritonitis. Treatment of infections even with the appropriate antibiotic is still associated with a high mortality but the use of adjuvant gut sterilization is promising, particularly in cases infected with Gram-negative enteric organisms. Infusions of fresh frozen plasma, blood and cryoprecipitate improve some systemic host defences and may be beneficial in the treatment and reduction of risk of infection.

Although in the last few years several cases of bacterial endocarditis have been reported in patients with obstructive hypertrophic cardiomyopathy, such as association is still infrequent and only in rare instances has pathologic examination of the cardiac lesions been possible. In this work a brief comment is made on the different forms of clinical presentation of the disease. The type of endocarditis, the relative incidence of responsible germs, and the prognosis are similar to those of other endocarditis. The clinical and autopsy findings of a female patient with alcoholic liver cirrhosis and symptomatic obstructive hypertrophic cardiomyopathy who developed a bacterial endocarditis of the mitral valve due to Staphylococcus aureus are reported. The patient died of an infected ascites. Some recent reports point to a higher incidence of bacterial endocarditis in cirrhotic patients, and this fact is felt to be an argument in favour of the hematogenous origin of spontaneous bacterial peritonitis.

Transient bacteremia during and after endoscopic procedures is a well- documented phenomenon, but complicated bacteremia such as endocarditis in patients at risk is considered to be extremely rare. The recommendations for prophylaxis before endoscopy in patients with valvular heart disease were recently released. We discuss 16 cases of complicated bacteremia that developed after endoscopy (eight cases previously published in the literature and eight cases we encountered). The endoscopic procedures were gastroscopy (five cases), sclerotherapy (six cases), sigmoidoscopy (three cases), and esophageal dilation (two cases). Fourteen patients had underlying disease: valvular heart disease (six patients), cirrhosis of the liver (five patients, one of whom also had a prosthetic knee), valvular heart disease and cirrhosis of the liver (two patients), and gastric carcinoma (one patient). The organisms involved were Streptococcus viridans (six cases), streptococcus group D (three cases), Streptococcus pneumoniae (two cases), Streptococcus microaerophilicus (two cases), Staphylococcus aureus (two cases), and Cardiobacterium hominis (one case). The patients presented with the following infections: endocarditis (12 patients), spontaneous bacterial peritonitis (two patients), septic arthritis (one patient), and brain abscess (one patient). The outcome was good in 15 patients; one patient died. Patients with valvular heart disease, cirrhosis of the liver, ascites, malignancies, or prosthetic joints who undergo endoscopic procedures should be considered for antibiotic prophylaxis.

Antimicrobial prophylaxis is used by clinicians for the prevention of numerous infections, including sexually transmitted diseases, human immunodeficiency virus infection, tuberculosis, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, malaria, infective endocarditis, pertussis, plague, anthrax, early-onset group B streptococcal disease in neonates, and animal bite wounds. Certain opportunistic infections such as Pneumocystis carinii pneumonia in immunocompromised patients also can be effectively prevented with primary antimicrobial prophylaxis. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infection. Optimal antimicrobial agents for prophylaxis are bactericidal, nontoxic, inexpensive, and active against the typical pathogens that cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be given within 30 to 60 minutes before the time of surgical incision. Antibiotic prophylaxis should be of short duration to decrease toxicity, antimicrobial resistance, and excess cost.

This is a retrospective study of Streptococcus suis infection in humans submitted to the National Streptococcal Referrence Center of Thailand from 1994 to 2001. There were 11 men and 6 women whose mean age was 46.24 years (range 1 month to 75 years). Among the men, two had known occupational and behavioral exposure to pork or meat products. Among the women, one was a butcher and three were housewives. Half of the patients had underlying diseases. One patient had congenital hydrocephalus, three patients had rheumatic heart disease and three were alcoholics. Two of these patients had a history of skin injury before infection. Nine patients had evidence of acute bacterial meningitis, four patients had infective endocarditis, two had the sepsis syndrome and two suffered from pneumonia and spontaneous bacterial peritonitis. The authors suspected that many cases are not reported particularly where pig-rearing or pork consumption are common. In the absence of an effective vaccine, prevention by public health surveillance is important. Prompt treatment of any cuts and wounds among pork-handlers is a sensible precaution. Furthermore, a high index of suspicion and early detection in order to identify and apply effective antimicrobial agents is necessary to successfully treat S. suis infection.

PCT is a new highly sensitive and specific marker of bacterial and fungi infection--to be used in differential diagnosis at Infectious Diseases Departments. Author in this paper presents structure and mechanism of stimulation of PCT as a factor of "early infection's fase" for many infectious agents: bacteria, fungi, viruses and parasites. PCT may be found useful in diagnosing diseases; for ex.: sepsis, meningitis, inflammation of respiratory system, spontaneous bacterial peritonitis (SPB) and other local inflammatory foci (otitis media, endocarditis). PCT level is low in systemic inflammatory response syndrome (SIRS) and multiorgan dysfunction syndrome (MODS) of non-infectious origin (< 0.5 ng/ml), medium in case of localized infections (1.0-2.0 ng/ml) and in severe cases of disseminated infections (sepsis-->SIRS-->MODS) high (approximately 20 ng/ml).

Transient bacteremia associated with various endoscopic procedures is a well-documented phenomenon. Clinically important bacteremias are very rarely seen, however, this malady has significant morbidity in susceptible patients with valvular heart disease, liver cirrhosis, malignancy and immune deficiency. This bacteremia is a complication that is generally observed secondary to upper endoscopy and other associated invasive procedures in at risk patients, and the more serious manifestations include spontaneous bacterial peritonitis, septic arthritis, meningitis, brain abscess and infective endocarditis. Infective endocarditis is an extremely rare complication of gastrointestinal endoscopy, and it has been convincingly documented in only seven cases. We report a case of native valve endocarditis due to Streptococcus intermedius in a patient with valvular heart disease as a consequence of routine upper endoscopy.

Despite widespread pneumococcal vaccination of children and adults, invasive pneumococcal disease (IPD) remains prominent. Using our database of all Streptococcus pneumoniae infections at the Veterans Affairs Medical Center, Houston, Texas, since 2000, we reviewed cases of IPD, defined as the isolation of pneumococci from any normally sterile body site. In 136 cases, the mean age of patients was 63 years; 43% were African American, a higher proportion than the 30% served by our hospital. One hundred sixteen patients (85%) had pneumonia, of whom 3 also had empyema. Seven had bacteremia with no apparent source, 5 meningitis, 5 spontaneous bacterial peritonitis, 3 septic arthritis, 2 endocarditis, and individual patients had osteomyelitis and/or localized abscesses. One hundred twenty-one patients (89%) had > or =1 underlying condition associated with susceptibility to pneumococcal infection, and another 8 (6%) were aged >65 years old. Thus only 5% of patients lacked a condition for which 23-valent pneumococcal polysaccharide vaccine (PPV23) is recommended. Fifty-five percent had been vaccinated; similar proportions of vaccine serotypes infected previously vaccinated and nonvaccinated patients. All but 2 isolates were fully susceptible to penicillin and cefotaxime as currently defined. Consistent with substantial replacement of infecting serotypes since the introduction of 7-valent pneumococcal conjugate vaccine (PCV7), none of the predominant infecting serotypes was included in PCV7, although all except for 6A were contained in PPV23. The overall mortality at 30 days was 16% and was similar in vaccinated and nonvaccinated subjects. IPD causes a wide spectrum of disease. Mortality is substantial. PPV23 is clearly not fully protective.

Antimicrobial prophylaxis is commonly used by clinicians for the prevention of numerous infectious diseases, including herpes simplex infection, rheumatic fever, recurrent cellulitis, meningococcal disease, recurrent uncomplicated urinary tract infections in women, spontaneous bacterial peritonitis in patients with cirrhosis, influenza, infective endocarditis, pertussis, and acute necrotizing pancreatitis, as well as infections associated with open fractures, recent prosthetic joint placement, and bite wounds. Perioperative antimicrobial prophylaxis is recommended for various surgical procedures to prevent surgical site infections. Optimal antimicrobial agents for prophylaxis should be bactericidal, nontoxic, inexpensive, and active against the typical pathogens that can cause surgical site infection postoperatively. To maximize its effectiveness, intravenous perioperative prophylaxis should be administered within 30 to 60 minutes before the surgical incision. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost.
