Brendan J. Mcmullan is an Infectious Disease Specialist based in Randwick, NSW, Australia. His work is focused on helping people when infections are more complex, persistent, or serious. In many cases, this means teaming up with other health professionals so care is safe, well planned, and timely.
Brendan looks after a wide range of conditions. This can include tough bloodstream infections like sepsis, and infections that affect the lungs, such as pneumonia and certain fungal infections. He also treats bone and joint infections in children, including osteomyelitis and septic arthritis, where early treatment really matters. For some patients, the issue is repeated or severe urinary tract infections, including UTIs in children.
He has experience supporting patients with infections linked to lower immunity, such as neutropenia and agranulocytosis, and conditions like MRSA. Over time, he also sees people with infections that affect the brain and nerves, including meningitis and cryptococcal meningitis. At times, his patients also have ongoing problems after infections, like Long Haul COVID.
Brendan’s training is grounded in careful assessment and current infectious disease practice. He works with families, carers, and local teams to explain what’s happening and what the next steps are. Where it helps, he also supports decisions around tests and treatment plans, including when fungal and other unusual infections are a possibility.
Research is part of how infectious disease care moves forward, and Brendan keeps up with new guidance as it comes to hand. Clinical trials can sometimes be an option for the right person, and he can talk through whether that’s relevant in a given situation.
