Late Identification of Chikungunya Virus in the Central Nervous System of a 2-Month-Old Infant: Persistence of Maternal-Neonatal Infection?

We report here a probable case of vertical transmission of chikungunya infection with confirmed maternal viremia close to labor that led to severe infection in the newborn. The newborn progressed with cutaneous lesions and irritability 2 months after vertical transmission, when chikungunya virus was detected in the infant's CSF by a molecular diagnostic test (real-time polymerase chain reaction).

Seroprevalence of Bartonella spp., Coxiella burnetii, and Hantavirus among people who inject drugs in Rio de Janeiro, Brazil: a retrospective assessment of a biobank.

The increasing use of illicit drugs imposes a public health challenge worldwide. People who inject drugs (PWID) are more susceptible to health complications due to immunosuppression associated with drug use and non-hygienic self-administration of substances, contaminants, and liquids. PWID are subjected to increased risk of acquiring and transmitting different pathogens (frequently functioning as sentinel cases for (re)emerging pathogens), including those transmitted by arthropods and vertebrate reservoirs in unhealthy environments.

Type III secretion-mediated killing of endothelial cells by Pseudomonas aeruginosa.

Pseudomonas aeruginosa, a common agent of septicemia, enters into human endothelial cellsin vitro but the effects of bacterial infection have not been addressed properly. In this study, human umbilical vein endothelial cells (HUVEC) were infected by the noninvasive PA103 and the invasive PAO1 P. aeruginosa strains and the viability of infected cells was assessed by the methyltiazole tetrazolium (MTT) assay.
