Abstract: The Northern Territory (NT) has the highest rates of sexually transmitted infections (STI) in Australia; however, the local prevalence of Mycoplasma genitalium (M. genitalium) has not been previously determined. This study was designed to review M. genitalium detection, to determine the regional NT prevalence and macrolide resistance rates. In our study the NT background prevalence of M. genitalium is 13%, with the highest detection rates occurring in central Australia and in correctional facility inmates. Symptomatic patients attending sexual health clinics have a positivity rate of 12%, but very high macrolide resistance. The decision to screen for M. genitalium should be based on several factors, including the prevalence of the infection in the local population; the availability of effective treatments; and the potential benefits and risks of detection and therapy.

BACKGROUND: Fungal keratitis is an ophthalmic emergency that can cause visual impairment and blindness. We reviewed the epidemiology and clinical features of fungal keratitis in a tropical Australian setting. OBJECTIVES: To document the clinical and microbiological characteristics of fungal keratitis in an Australian tropical setting. METHODS: A retrospective cohort study of patients with fungal keratitis from October 2014 to December 2022 was conducted at Royal Darwin Hospital, Northern Territory, Australia. We reviewed all patients with culture-proven fungal keratitis and their outcomes. RESULTS: There were 31 patients identified. Aboriginal and Torres Strait Islander (ATSI) patients were of a significantly younger median age (28 years) compared to non-ATSI patients (42 years), and they also presented later to health care. Contact lens use and ocular trauma were the most common predisposing factors. Most patients presented with a corneal infiltrate and corneal epithelial defect, and the central visual axis was affected in 54% of patients. Curvularia spp. and Fusarium spp. were the commonest causative fungi (39% and 30% respectively). CONCLUSIONS: Our series is different and reveals a wider range of fungal species identified over the 7 years of the study, in particular, a range of Curvularia spp. were detected. Access to eye health services in rural and remote settings is important, particularly for ATSI patients, as morbidity remains high.
RESUMO
Group B streptococcus (GBS) is a significant cause of perinatal morbidity and mortality; prophylactic antibiotics in the obstetric population can mitigate the risk of neonatal infection. The antibiotic of choice is penicillin; however, in women who have a penicillin hypersensitivity, clindamycin is the preferred agent. Worldwide resistance to clindamycin is rising in GBS isolates. In the Top End of the Northern Territory of Australia, we reviewed 113 GBS isolates in 2023. These GBS isolates revealed a 30% resistance to clindamycin. This rate has considerably increased since the Australia-wide survey published in 2011 where GBS resistance to clindamycin was quoted at 4.2%. As a result of this study, we are advocating for a change in practice in patients with known GBS resistance with penicillin hypersensitivity.
