In a 5-year prospective study in a Hong Kong teaching hospital there were 344 clinically significant episodes of paediatric septicaemia. Many of the microbiological and clinical features were similar to those reported in Japanese and Western studies but there were some important differences. Half of the episodes (or 70% if neonatal infections are excluded) were community-acquired. The commonest organisms found were Salmonella spp (15% of all and 27% of community-acquired infections); this was related to the high local incidence of salmonellosis and typhoid fever. Salmonella typhi, which was responsible for one-third of the salmonella septicaemias, was usually seen in school-age children, while non-typhoid salmonellae were common in infants. Methicillin-resistant Staphylococcus aureus, which are now endemic in Hong Kong hospitals, was a common cause of hospital-acquired septicaemia. Pneumococcal septicaemia accounted for 22% of episodes in infants and pre-school children, but Haemophilus influenzae was uncommon (2% of all episodes) and there was no case of meningococcal septicaemia. The rarity of invasive infection with H. influenzae and Neisseria meningitidis in Hong Kong children is unexplained.

We have treated 42 episodes of pediatric infections with sulbactam/ampicillin since 1987. Included were 9 cellulitis, 9 urinary tract infections, 5 cervical lymphadenitis, 4 meningitis, 2 thoracic empyema, 2 osteomyelitis, 2 sepsis, 1 furuncle, 1 perianal abscess, 1 dental abscess, 1 peritonsillitis, 1 salmonellosis, 1 shigellosis, 1 peritonitis, 1 suppurative thyroiditis, 1 infective endocarditis. Responsible pathogens were Escherichia coli in 8, Staphylococcus aureus in 6, Hemophilus influenzae in 2, Streptococcus pneumoniae in 3, Streptococcus viridans in 2, Staphylococcus epidermidis in 1, Bacteroides fragilis in 1, Salmonella D1 in 1, Shigella sonnei in 1, Klebsiella pneumoniae in 1, Enterobacter agglomerans in 1, Acinetobacter calcoaceticus in 1, Enterobacter cloacae in 1, group A beta-hemolytic streptococcus in 1, and polymicrobial infection in 4 cases. Thirty-nine out of 41 (95%) clinically evaluable patients cured and all (34/34) bacteriologically evaluable patients eradicated their pathogens after treatment with sulbactam/ampicillin. Side reactions were seen in five patients; one maculopapular skin rash, one hemolytic anemia, two diarrhea, and one liver function impairment plus leukopenia. All these reactions were transient and did not require interruption of therapy. These results indicate that sulbactam/ampicillin is safe and effective in the treatment of common pediatric infections beyond the neonatal period.

Bacterial infections occur often in HIV-infected patients. Defects in both cell-mediated and humoral immunity are associated with an increased frequency of infections due to encapsulated and enteric bacteria. Pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae, and other pathogens may occur early in the course of AIDS and have typical clinical presentations. Bacteremia is extremely common, and patients frequently fail to develop protective elevations in specific antibodies following infection. Recurrences are noted in up to one third of patients, and suppressive antimicrobial therapy may be required. The frequency of salmonellosis is increased as much as 20-fold in AIDS patients and is associated with bacteremia in more than 40 per cent of cases. Salmonella, Shigella, and Campylobacter infections in HIV-infected individuals may precede an AIDS diagnosis, may fail to respond to appropriate therapy, or may recur after completion of treatment. Prevention of bacterial infections with antibiotics or immunotherapy, or both, is recommended for children with AIDS or ARC.

The Limulus test was carried out for endotoxin determination using a synthetic chromogenic substrate after perchloric acid(PCA) treatment to remove inhibiting substances in the blood. PCA treatment completely removed non-specific amidolytic activity and other factors which interfered with the Limulus test. The recovery of added endotoxin was about 100% irrespective of animal species. Endotoxin levels in PCA-treated blood plasma of healthy domestic animals were invariably below 1 pg ml-1. Many of the cows with gangrenous mastitis, from which Gram-negative rods were isolated, showed high endotoxin levels ranging from 22.8 to 138.0 pg ml-1. Endotoxin was also detected in the blood of cows affected with salmonellosis, colibacillosis, Haemophilus somnus infection and urethritis associated with Proteus.

T-1982 (cefbuperazone) was evaluated in 25 children with a suspicion of bacterial infections, of the 21 confirmed bacterial infections, 18 were shown to be effective (efficacy rate, 85.7%). The diagnosis included pneumonia (4), bronchopneumonia (3), acute bronchitis (4), acute pharyngitis (1), acute laryngitis (1), acute epiglottitis (1), acute enterocolitis (3), cervical lymphadenitis (1), acute pyelonephritis (1) and suspected septicemia (2). The etiologic pathogens recovered were Haemophilus influenzae (4), Staphylococcus aureus (2), Salmonella typhimurium (1), Salmonella subgenus (1), and enteropathogenic Escherichia coli (2). Among these strains, 7 strains were eradicated after treatment. A case of suspected septicemia and 2 cases of acute enterocolitis with Salmonella infection were not effectively treated with T-1982. The serum half-life of T-1982 was 1.2 hours after an intravenous bolus injection. No severe adverse reaction was encountered with the T-1982 therapy. The data suggest that T-1982 is an effective and safe parenteral antibiotic in the treatment of susceptible pediatric bacterial infections.

It has been suggested that the therapeutic use of oral chloramphenicol in animals is liable to select resistance to antibiotics and that the resistance may jeopardise the treatment of infections in man. At present this risk appears minimal; resistance to chloramphenicol in animal bacteria may well be selected by the increasing use of semi-synthetic penicillins because of linkage between genes coding for production of beta-lactamase and resistance to chloramphenicol. Among salmonellae, the strains causing enteric fever have no animal reservoir and the few food poisoning incidents in man that require therapy can be treated with antibacterial agents such as trimethoprim. Chloramphenicol is not now the antibiotic of choice for any human infection except perhaps a few caused by Haemophilus influenzae. Resistance to antibiotics in 'human' cultures has largely been selected by the use of antibiotics in human medicine. Control of salmonellosis is essentially a public health, not a therapeutic problem.

Recent developments (including more accurate assays) that have led to revised recommendations for route of administration, dosage, and indications for chloramphenicol are reviewed. Chloramphenicol is most bioavailable by the oral route; doses of 75 mg/kg/day provide adequate therapeutic concentrations for most clinical indications. Serum concentrations of the drug should be monitored to ensure adequate therapeutic concentrations and to avoid toxicity. This is particularly important in newborns, in patients with liver dysfunction, and in those receiving concomitant drugs that may influence free chloramphenicol concentrations. The indications for chloramphenicol therapy evaluated are: Haemophilus influenzae infections, anaerobic infections, salmonellosis, Rocky Mountain spotted fever, and eye infections. Chloramphenicol is useful in the treatment of invasive Haemophilus influenzae infections resistant to ampicillin, in selected anaerobic and ocular infections, and for rickettsioses in patients under the age of eight years. Because the rare but life-threatening complication of chloramphenicol (aplastic anemia) persists, indications for the drug's clinical use are narrowing once again with the advent of third-generation cephalosporins highly active against gram-negative bacilli including ampicillin-resistant H. influenzae. Similarly, metronidazole or clindamycin may be preferred for some anaerobic infections.

Seventeen complicated outbreaks of infectious coryza in layer, broiler-breeder, and broiler flocks were studied. In the layer flock outbreaks, drops in egg production of up to 35% were seen. In the broiler flocks and several of the layer flocks, losses due to persistent mortality and/or culling varied between 2 and 5%. Signs of infectious coryza in both layers and broiler-breeders were typical; in broilers, however, swollen head-like syndrome was seen. Except in one flock, no viral diseases were clinically or serologically detected. Excluding broiler-breeders, birds from most other flocks were serologically positive for Mycoplasma gallisepticum, and some were also positive for M. synoviae. Haemophilus paragallinarum was isolated from all of the outbreaks, but only as a pure culture in three outbreaks. Isolation of H. paragallinarum from sites such as liver, kidney, and particularly tarsal arthritis and ocular globes appears to be reported for the first time. Serovar A was isolated in eight outbreaks, serovar B in six, serovar C in one, and untypable serovars in two. The severity of these infectious coryza outbreaks may have been increased by concurrent salmonellosis, pasteurellosis, and mycoplasmosis, although under certain conditions H. paragallinarum is able to cause septicemia. Ten of the outbreaks occurred in birds vaccinated against infectious coryza; this may be due to the use of vaccines that do not provide protection against the types of H. paragallinarum that affect poultry in the region.

In 1996 there were 65,024 notifications to the National Notifiable Diseases Surveillance System. The record high number of Ross River virus infection notifications was of particular note. The highest rates were recorded in Western Australia, where an outbreak was documented in the South West, and in Queensland. Most cases occurred in the late summer and early autumn months. The number of measles cases has continued to fall markedly following the outbreak in 1993 and 1994. Rubella notifications also fell in 1996. The number of cases of pertussis remained at a similar level to that recorded in recent years, the highest notification rate being recorded for children under the age of one year. A peak in late 1996 marked a resurgence in the pertussis epidemic which has continued into 1997. Notifications of Haemophilus influenzae type b continued to decline reaching a record low rate of 0.3 notifications per 100,000 population. For the enteric diseases, the number of cases of campylobacteriosis rose, with an annual adjusted notification rate of 100.4 per 100,000 population; more notifications were received for this disease than for any other in 1996. The number of hepatitis A cases also rose relative to 1995. This is a reversal of the trend observed in recent years when the notification rate fell. The number of cases of salmonellosis and shigellosis remained stable. Notifications for chlamydial infection and gonococcal infection rose relative to 1995, whilst those for syphilis fell.

In 1997 there were 89,579 notifications to the National Notifiable Diseases Surveillance System. A notable feature of 1997 was the pertussis outbreak which peaked towards the end of the year and resulted in 10,668 cases being notified. The highest number of notifications received was for hepatitis C (unspecified) with 19,692 notifications; this is the first year for which data have been reported for New South Wales and South Australia for this disease category. The number of measles cases rose after the low number reported in 1996 but is still well below the number reported in the outbreak years of 1993 and 1994. Rubella notifications continued to decline in 1997. Notifications of Haemophilus influenzae type b appeared to have stabilised at a low rate, having declined markedly after introduction of the conjugated vaccine in 1992. The number of cases of campylobacteriosis remained steady after having risen for several years. Notifications of hepatitis A cases rose considerably, much of this being due to one outbreak in New South Wales. The number of cases of salmonellosis rose while shigellosis numbers dropped slightly. Notifications for chlamydial infection and gonococcal infection continued to rise, whilst those for syphilis continued to fall.
