A 59-year-old woman presented with fever and malaise and was found to have Lactococcus lactis bacteraemia. L. lactis infection is rare in humans with few reported cases, with most associated with dairy food product ingestion. The patient reported use of a multistrain over-the-counter probiotic supplement. After isolation of L. lactis from blood culture, the patient was treated empirically with ertapenem and amoxicillin and displayed clinical improvement. She remained well after completion of antibiotic regimen and discontinued probiotic supplementation use. We review the clinical presentation of L. lactis infection including diagnosis, identification and treatment.

Mycobacterium tuberculosisis highly endemic in the Philippines. The diagnosis is challenging with its non-specific presentation and the organism could extend to any of the organs. Interestingly, bacterial peritonitis arising spontaneously from gastrointestinal tuberculosis (TB) in an otherwise healthy, non-cirrhotic patient is quite unusual. In this paper, we discuss the case of a 27-year-old HIV-seronegative woman with massive intraperitoneal mixed bacterial and tuberculous abscess presenting 20 months after being diagnosed with bacteriologically confirmed gastrointestinal TB. Repeated large-volume paracentesis was done to drain out the infected ascites instead of inserting a percutaneously implanted catheter. Clinical improvement was noted and she was discharged after 12 days of intravenous antibiotics. She had completed 6 months of antituberculosis therapy and been well since then. The case has demonstrated that repeated paracentesis along with appropriate antibiotic regimen, may be a viable option for patients with TB and bacterial coinfected peritonitis. And possibly, peritoneal TB may increase the risk for (spontaneous) bacterial peritonitis.

Pseudomonal scleritis complicating scleral buckling surgery is described in a patient unable to tolerate systemic side effects from aminoglycoside antibiotics. Particular reference is made to a novel antibiotic regimen comprising systemic ceftazidine and ciprofloxacin.
