Infection with group A streptococci (GAS) can lead to the development of severe postinfectious sequelae such as rheumatic fever (RF). In Thailand, RF and rheumatic heart disease (RHD) remain important health problems. More than 80% of GAS circulating in this population are non-M antigen typeable by conventional M serotyping methods. In this study, we determine the M protein sequence types of GAS isolates found in northern Thailand. The emm genes from 53 GAS isolates, collected between 1985 and 1995 from individuals with pharyngitis, impetigo, acute RF (ARF), RHD, or meningitis as well as from individuals without infections, were amplified by PCR and sequenced. Thirteen new sequence types that did not show homology to previously published sequences were characterized. Six of these sequence types could be isolated from both skin and throat sites of impetigo and pharyngitis/ARF patients, respectively. In many cases we could not specifically differentiate skin strains or throat strains that could be associated with ARF or acute glomerulonephritis. Antigenic variations in the emm gene of the isolates investigated, compared to published M protein sequences, were predominantly due to point mutations, small deletions, and insertions in the hypervariable region. One group of isolates with homology to M44 exhibited corrected frameshift mutations. A new M type isolated from an RHD patient exhibited nucleotide sequence corresponding to the N terminus of M58 and the C terminus of M25, suggesting that recombination between the two types may have occurred. This study provided epidemiological data relating to GAS endemic to northern Thailand which could be useful for identification of vaccine candidates in a specific region of endemicity.

Neisseria meningitidis infection (meningococcemia) is very common throughout the world. It usually presents as meningitis or sometimes pharyngitis. A gastroenteritis-like syndrome, with diarrhea, vomiting and abdominal pain, may occur in children but is very rare in adults. Search of the medical literature revealed only 3 such cases, all in young adults. We report an 80-year-old woman who presented with fever, diarrhea and abdominal pain. Meningococcus infection was later suspected, and proved by culture. Although treatment was intensive and included ceftriaxone (Rocephin) and garamycin, she did not respond and died 40 hours after admission. We draw attention to the possibility that what is usually a common symptom can be the first presentation of a serious, often fatal condition.

Neisseria meningitidis is known to cause a spectrum of diseases, including bacteraemia without sepsis, meningococcaemia without meningitis, meningitis with or without meningococcaemia, and chronic meningococcaemia. Less common manifestations of meningococcal infection include pharyngitis, pneumonia, pericarditis, urethritis and arthritis. To our knowledge, there have been no previous reports of N. meningitidis causing prosthetic joint infection. Herein, we report a case of primary meningococcal arthritis in a woman with a prosthetic knee joint. After surgical drainage the prosthesis was retained and the patient received appropriate and prolonged antibiotic treatment. The outcome was favourable, as with primary meningococcal arthritis affecting native joints.

This review describes the microbiology and management of meningitis and shunt infections caused by anaerobic bacteria in children. The predominant anaerobes recovered in meningitis are Bacteriodes spp., Bacteriodes fragilis, Fusobacterium spp., and Clostridium spp. Peptostreptococcus, Veillonella, Actinomyces, Propionibacterium acnes, and Eubacterium are less commonly isolated. The predisposing conditions for meningitis are acute or chronic middle-ear infection, sinusitis, pharyngitis, and pulmonary infections. In newborn and preterm infants the predisposing conditions are rupture of membranes, amnionitis, fetal distress, necrotizing enterocolitis, gastric perforation and subsequent ileus followed by bacteremia, aspiration pneumonitis and septicemia, infected ventriculoperitoneal or ventriculoatrial shunt, and complicating dermal sinus tract infections. Shunt infection with Propionibacterium spp. has been reported in children, especially in association with ventriculoauricular and ventriculoperitoneal shunts. Clostridium perfringens has been recovered from infants with a ventriculoperitoneal shunt. Multiple-organism meningitis was reported as a complication of ventriculoperitoneal and lumboperitoneal shunts that perforated the gastrointestinal tract. Early recognition and effective therapy are essential to recovery. Management of meningitis includes the use of antimicrobials effective against anaerobes that penetrate the blood-brain barrier. These include metronidazole, chloramphenicol, the combination of a penicillin and a beta-lactamase inhibitor, and carbapenems. The treatment of shunt infection includes antimicrobial therapy and removal of the shunt.

The clinical and laboratory findings in 21 patients with listeriosis are described and the subject is reviewed. Eleven of the infections were septicemias of newborns, eight were meningitis in infants or adults, and two other children had unusual manifestations.Neonatal septicemia was rapidly fatal; one of 11 infants survived. The disease often seemed traceable to mild maternal infection during the third trimester usually leading to premature delivery of critically ill babies. Only awareness of the possible presence of listeriosis and early antibiotic therapy seem capable of reducing this high mortality.Tissues from autopsies showed characteristic microscopic necrotic foci with mononuclear infiltration progressing to microabscesses containing small Gram-positive rods. Lesions were found in the one placenta examined.Five infants with meningitis recovered, and one of three affected adults. Specific diagnosis depends on demonstrating Listeria monocytogenes; differentiation from other forms of acute meningitis cannot be made clinically.One older child had septicemia and another had listerial pharyngitis. Both recovered.

From July 1999 to June 2004, we evaluated Streptococcus pneumoniae bacteremia in 40 children in Kamikawa and Soya Subprefectures in Hokkaido by obtaining the patient's information from 7 out of 9 hospitals in the area. The incidences of S. pneumoniae bacteremia in children aged < 2 years and < 5 years were 79.1 and 63.4. Median age was 19.6 months with a range from 4 months to 4 years. Thirty-one (77.5%) of the total were less than 2 years old. All of the children were admitted. The diagnoses were occult bacteremia in 12 patients, pneumonia or bronchitis in 11, pharyngitis in 7, pneumonia and acute otitis media in 5, acute otitis media in 3, orbital cellulitis in 1, and arthritis in 1. All of the patients had fever and temperatures and 35 (87.5%) of them were more than 39 degrees C. Ten patients had a febrile convulsion. Twenty-nine had a high total white blood cell counts (> 15,000/microg/ml) and 31 had positive CRP values (> 0.6 mg/dl) on admission. Meningitis and poor prognosis did not occur after occult bacteremia in our patients. We studied the susceptibility to penicillin G in 22 strains of S. pneumoniae isolated from the children. One and 18 strains were penicillin-resistant (MIC > or = 2.0 microg/ml) and intermediate (MIC 0.1-1.0 microg/ml).

A 20-year-old woman developed symptoms of pharyngitis followed by generalised skin rash and pulmonary infiltrates with cavitation. Arcanobacterium haemolyticum was identified in blood culture, which was susceptible to the antibiotics given. After initiating pathogen-directed therapy, the patient recovered completely. A. haemolyticum is a Gram-positive rod that can grow under aerobic and anaerobic conditions. The pathogen causes a characteristic haemolysis when cultured on human blood agar. A. haemolyticum causes pharyngitis and skin rash, particularly in adolescents. If the infection is not treated adequately, progression to more severe infections such as pneumonia, meningitis and sepsis can occur. The treatment of choice is a macrolide antibiotic.

Streptococcal organisms, part of the normal human bacterial flora, occasionally become infectious pathogens responsible for a wide array of clinical syndromes, ranging from mild pharyngitis to death. Notably, infections due to group A and group B beta-hemolytic strains are well known for causing invasive disease leading to death. These deaths, while often suspected clinically, occasionally are not diagnosed until autopsy. We present 3 rapid deaths, with very different presentations, due to streptococcal infection. Two decedents experienced sudden deaths due to pneumonia and severe meningoencephalitis caused by group B beta-hemolytic streptococcal infection, a common cause of neonatal meningitis but only rarely reported in nonpregnant adults. The final case involves a 69-year-old male who presented to the emergency room with a complaint of shoulder pain but over the next several hours developed signs of necrotizing fasciitis, became septic, and died. While antemortem cultures were negative, owing to antibiotic administration, postmortem cultures of bone and deep soft tissue were positive for group A beta-hemolytic Streptococcus sp. Acute and sudden deaths due to infectious etiology represent an uncommon yet well-documented occurrence. The importance of appropriate postmortem cultures in these situations and a review of the literature will be discussed.

Kawasaki Disease is a small-to-medium-vessel vasculitis that preferentially affects children. Kawasaki Disease can occur in adults, but the presentation may differ from that observed in children. Typical findings in both adults and children include fever, conjunctivitis, pharyngitis, and skin erythema progressing to a desquamating rash on the palms and soles. Adults more frequently present with cervical adenopathy (93% of adults vs. 15% of children), hepatitis (65% vs. 10%), and arthralgia (61% vs. 24-38%). In contrast, adults are less frequently affected by meningitis (10% vs. 34%), thrombocytosis (55% vs. 100%), and coronary artery aneurysms (5% vs. 18-25%). We report a case of acute Kawasaki Disease in a 24-year-old man who presented with rash, fever, and arthritis. He was successfully treated with high-dose aspirin and intravenous immunoglobulin (IVIG). Our case highlights the importance of considering Kawasaki Disease in adults presenting with symptoms commonly encountered in a general medical practice.

An association between viral infection and late-onset disease caused by group B Streptococcus (GBS), was systematically looked for in neonates hospitalized for fever during a 3 1/2 year period. Five neonates between 5 to 12.5 months of age presented with meningitis (2 cases) or with septicemia (3 cases) caused by GBS. Viral culture, immunofluorescence, and assay of IFNalpha in blood and cerebrospinal fluid were performed. A viral infection was proved in 4 cases and suspected in 1 case (rash and pharyngitis). We speculate that viral infection may provoke late-onset disease in colonized infants with GBS.
