Late-onset and recurrent neonatal Group B streptococcal disease associated with breast-milk transmission.

The purpose of the study was to determine the epidemiological relationships in three unrelated cases of neonatal late-onset Group B streptococcal (GBS) disease and maternal breast-milk infection with GBS. All deliveries were by cesarean section; case 1 was at term, and cases 2 and 3 were at 32- and 33-wk gestation, respectively. Case 1 relates to a mother with clinical mastitis and recurrent GBS infection in a 20-day-old male infant.

Pasteurella multocida: a case report of bacteremic pneumonia and 10-year laboratory review.

Pasteurella multocida is a normal oral commensal in animals. Animal bites are often complicated by severe wound infection due to P. multocida, but systemic infection is rare.

Leptospirosis presenting as a haemorrhagic fever in a traveller from Africa.

Leptospirosis is usually a mild illness, although the severity of clinical manifestations may vary between the serovars of leptospires. In May 1993, a 48-year-old man from Ghana presented with severe icteric leptospirosis, initially managed as viral haemorrhagic fever. The causative serovar, bataviae, had not been previously diagnosed in human infection in Australia.

Hepatitis A and evidence against the community dissemination of Helicobacter pylori via feces.

Seroprevalence data from 1501 subjects was used to test the hypothesis that Helicobacter pylori may be transmitted by the fecal-oral route. Antibody to hepatitis A virus was used as a marker of fecal-oral exposure. Of the 1501 subjects, 35.

Haemophilus paraphrophilus vertebral osteomyelitis.

Objective: To report the first case of Haemophilus paraphrophilus vertebral osteomyelitis--the second reported case of osteomyelitis of any site caused by this organism.

Clinical Features: A 41-year-old male bus driver with no significant previous medical history presented with severe abdominal and back pain, which was eventually localised to the eleventh thoracic vertebra (T11). H.

Evaluation of direct disc diffusion susceptibility testing for bacteriuria using diluted urine against standard CDS method.

Consecutive urine specimens with > or = 10(9) organisms/L on microscopy were diluted 1:100 and direct disc diffusion susceptibility tests performed. Subsequently, the standard Calibrated Dichotomous Sensitivity (CDS) test was performed on all isolates. Urines with > 2 Isolates or where growth was < 10(8) colony forming units (CFU)/L were excluded.

Pasteurella multocida meningitis in a two-day old neonate.

A normal full-term baby boy, born by vaginal delivery, became ill on day 2 with fever and failure to feed. CSF examination revealed 260 x 10(6)/l leucocytes, mainly mononuclears, protein 2 g/l and glucose zero. Pasteurella multocida was isolated in pure culture from the baby's CSF, blood and umbilicus and from the mother's vagina.

Listeria monocytogenes peritonitis associated with CAPD.

Listeria monocytogenes peritonitis developed in a 67-year-old man on continuous ambulatory peritoneal dialysis following a catered luncheon. Alcoholic liver disease was a predisposing factor. L.

Shigella dysenteriae type 1 enterocolitis.

Shigella dysenteriae type 1 is much more virulent than Shigella flexneri and sonnei which are endemic in Australia. This report describes a 22 year old woman who acquired Shigella dysenteriae type 1 whilst travelling in India. During the course of her illness, she developed severe enterocolitis for which a subtotal colectomy was performed.

Two concurrent epidemics of enteroviral meningitis in an obstetric neonatal unit.

A small epidemic of viral infection occurred in a neonatal unit. It involved 11 infants, all of whom recovered. Echovirus 11 was the cause of illness in six infants, coxsackie B3 in four, and one infant had a biphasic illness, due first to echo 11, then to coxsackie B3.

Possible role of enteric organisms in the pathogenesis of ankylosing spondylitis and other seronegative arthropathies.

One-hundred eighty-five clinical isolates of Salmonella sp., Shigella sp., Escherichia coli, and Campylobacter sp.

Pulmonary strongyloidiasis and lung abscess.

We report a case of lung abscess associated with pulmonary strongyloidiasis which occurred in an asthmatic patient three years after migrating to Australia from Burma where strongyloidiasis is endemic. Thiabendazole was effective in eradicating the Strongyloides infection.

Chronic pulmonary infection with Salmonella typhimurium.

The first report of a case of chronic sputum carriage of salmonella is presented. The patient was a 51-year-old male with pulmonary cavitation and mycetoma, who developed pulmonary infection with Salmonella typhimurium after rectal surgery, and subsequently has carried the salmonella in his sputum for 18 months to date.

Single-dose parenteral antibiotics as prophylaxis against wound infections in colonic operations.

A study of 77 patients undergoing elective operations on the colon and rectum, where wounds were subject to contamination by fecal flora, did not demonstrate that the addition of a preoperative oral regime to parenteral antibiotics alone further decreased the incidence of wound infection. The authors feel that the use of single-dose clindamycin and cephazolin intravenously preoperatively has been shown to be a very effective method of preventing wound infection in elective colonic resections.

Pneumococcal peritonitis in adolescent girls.

Two cases of pneumococcal peritonitis, which occurred after puberty in previously healthy adolescent girls, are described. In each case, the infection was caused by a Type 1 tetracycline-resistant pneumococcus.
