A case history of a 15-year-old schoolgirl with fluctuating bilateral uveitis, bilateral stromal keratitis with vascularisation, and bilateral deafness associated with tinnitus and balance disturbance is described. Three years from the onset of her clinical signs she died of a sudden cardiac arrest caused by endocarditis associated with valvular and arterial lesions. Chlamydia psittaci was isolated from her conjunctiva. In her blood type-specific antichlamydial antibody at a level of 1/64 against her own isolate was detected. The clinical findings in this patient were suggestive of a Cogan's syndrome. It is highly probable that the chlamydia isolated from the eyes was responsible for her various lesions.

A 34-year-old woman died of left-heart failure due to combinated aortic-valve disease three years after manifestation of Cogan's syndrome characterized by sudden inner-ear deafness, loss of equilibrium, interstitial keratitis, and progressive loss of vision during pregnancy. At necropsy there was evidence of recurrent endocarditis of the aortic valves with stenosis and regurgitation, severe angitis of the thoracic aorta with marked secondary sclerosing changes as the cause of the heart failure. Angitis within the optical fasciculus and stato-acoustic nerve was the cause of the vestibular and optical defects. Primary changes in the visual and auditory cortices, the retina and inner ear were excluded as causes. There was also acute membrano-proliferative glomerulonephritis, which may have been coincidental.

A 61-year-old pig farmer was found to be suffering from meningitis caused by Streptococcus suis type II. He was successfully treated with intravenous penicillin G but was left with permanent deafness. B-cell lymphoma was also diagnosed one year later. S. suis is a zoonotic pathogen which causes meningitis, septicemia and endocarditis in pigs. Human infection is rare and often presents as meningitis with the sequela of permanent deafness. It has previously been reported in pig rearing countries such as Holland or Hong Kong. This is the second documented case of human meningitis caused by S. suis in Taiwan, which is also a major pig rearing country in Asia. Infections caused by viridans streptococci or other beta-hemolytic streptococci in Taiwan may therefore actually be due to S. suis. Further investigation of the possibility of the underlying deficiency of humoral immunity is warranted.

A recent outbreak of Streptococcus suis infection associated with the slaughter, preparation or consumption of pigs in Sichuan, China has led to concerns that similar outbreaks could occur in other Asian countries. Although the pig farming industry is flourishing in Taiwan, reports of S. suis infection remain rare. We report 2 cases of S. suis meningitis successfully treated with ceftriaxone and penicillin. Previous reports of S. suis infection from the English literature are reviewed and the clinical data of cases reported in Asian and European countries are summarized. In Europe, there was good correlation between clinical disease and porcine contact, while few cases in Asia reported this association. Meningitis remained the most common presentation of infection in both areas (84.6% and 75.2%, respectively), followed by sepsis (15.4% and 18.6%, respectively), which had a higher mortality rate, particularly for splenectomized patients. Other clinical presentations included enteritis, arthritis, endocarditis, pneumonia, spondylodiscitis, endophthalmitis, uveitis and peritonitis. Deafness was a distinct sequelae (50.5% in Europe and 51.9% in Asia) after recovery from S. suis infection, especially in patients with meningitis. Not all commercial identification systems for streptococci could offer adequate speciation for S. suis. When viridans group streptococci are isolated from patients with meningitis and sepsis, prompt and correct identification of isolates to the species level should be performed, especially in areas with a high prevalence of S. suis diseases.

Streptococcus suis is a zoonotic pathogen which causes meningitis, bacteremia, and endocarditis in pigs. Human infection is rare and often presents as meningitis with the sequela of permanent deafness and endocarditis. Previous cases were reported from pig-rearing countries such as Holland and Hong Kong. We report a 55-year-old bedridden man with S. suis meningitis complicated with ventriculoperitoneal shunt infection and lumbar spine spondylodiscitis. He presented with fever, delirium, neck stiffness, lower leg weakness and sudden onset hearing loss for several days. He was successfully treated with intravenous antibiotics, ventriculoperitoneal shunt replacement, lumbar spinal laminotomy and discectomy. Cerebrospinal fluid culture initially misidentified the organism as Streptococcus acidominimus, and S. suis was later identified by 16S rRNA sequencing. Misidentification of the microbiological findings may lead to a failure to correctly diagnose this disease. S. suis meningitis should be included in the differential diagnosis of patients with meningitis and sudden hearing loss.

Streptococcus suis is a major swine pathogen, an emerging zoonotic agent responsible for meningitis, endocarditis and septicaemia followed by deafness in humans. The development of antimicrobial resistance in S. suis increases the risk for therapeutic failure in both animals and humans. In this study, we report the synergism of combination therapy against multi-resistant S. suis isolates from swine. Twelve antibiotic profiles were determined against 11 S. suis strains. To investigate their synergistic/antagonistic activity, checkerboard assay was performed for all the possible combinations. In-vitro killing curves and in-vivo treatment trials were used to confirm the synergistic activity of special combinations against S. suis dominant clones. In this study, 11 S. suis isolates were highly resistant to erythromycin, clindamycin, trimethoprim/sulfamethoxazole, and tetracycline with ratios of 80-100%, and the resistance percentages to enrofloxacin, florfenicol, and spectinomycin were ~50%. The checkerboard data identified two combination regimens, ampicillin plus apramycin and tiamulin plus spectinomycin which gave the greatest level of synergism against the S. suis strains. In-vitro kill-curves showed a bacterial reduction of over 3-logCFU with the use of combination treatments, whilst the application of mono-therapies achieve less than a 2-logCFU cell killing. In-vivo models confirm that administration of these two combinations significantly reduced the number of bacterial cells after 24 h of treatment. In conclusions, the combinations of ampicillin plus apramycin and tiamulin plus spectinomycin showed the greatest synergism and may be potential strategies for treatment of multi-resistant S. suis in animal.
