First report of Entamoeba histolytica infection from Timor-Leste--acute amoebic colitis and concurrent late development of amoebic liver abscess in returned travellers to Australia.

This communication reports invasive amoebic colitis and late onset amoebic liver abscess in three members of a group of 12 Australian travellers to Timor-Leste (TL). This is the first report of Entamoeba histolytica infection from TL. Clinicians in Australia need to consider amoebiasis in the differential diagnosis in travellers returning with colitis, abdominal pain and fever.

Congenital cytomegalovirus infection is a significant cause of moderate to profound sensorineural hearing loss in Queensland children.

Aim: To investigate the proportion of children with moderate to profound hearing loss who have congenital cytomegalovirus (cCMV) infection.

Method: Retrospective analysis of CMV dried blood spot (DBS) polymerase chain reaction (PCR) in children with moderate to profound hearing impairment referred to tertiary referral centres in Queensland. Participants were under 18 years old with no readily identified cause of hearing impairment, between 2008 and 2011.

Disseminated varicella infection caused by varicella vaccine strain in a child with low invariant natural killer T cells and diminished CD1d expression.

Background: Live attenuated varicella vaccine is considered a safe vaccine with serious adverse effects reported only in immunocompromised children. We describe a severe life-threatening infection with varicella vaccine virus causing rash and pneumonitis in a 6-year-old boy with no apparent immunodeficiency.

Methods And Results: Polymerase chain reaction (PCR) analysis of vesicle swab samples demonstrated varicella zoster virus (VZV).
