Group A Streptococcus puerperal sepsis with invasive neonatal infection: A fatal case.

Neonatal invasive Group A Streptococcus (GAS) infection is a rare occurrence nowadays. Prior maternal vaginal colonization is an important factor in early neonatal disease. We report a case of invasive and fatal infection in a neonate. At Day 1 of life, a term baby was found to be lethargic, with poor feeding, and later became unresponsive. Consequently, the baby was immediately brought to the Emergency Department of Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan via ambulance. Despite the active resuscitation efforts in the hospital, the baby died. An autopsy was carried out to determine the cause of death. The mother was noted to have puerperal pyrexia secondary to vaginal discharge. Her high vaginal swab culture was positive for GAS. GAS was also isolated from the intracardiac blood, pleural fluid, peritoneal fluid, and umbilical swab of the baby, giving evidence to the aetiology of the mortality. Vaginal colonization of GAS is an important factor for high morbidity and mortality for both mother and infant due to its invasiveness and virulence.

Seroprevalence of Toxoplasma gondii infection among patients in Hospital Universiti Sains Malaysia.

Toxoplasmosis is a worldwide endemic zoonotic infection caused by the obligate coccidian parasite Toxoplasma gondii. To assess the seroprevalence of T. gondii infection among hospital population of Hospital Universiti Sains Malaysia (HUSM), a cross-sectional study was conducted using serum samples of 102 participants. Samples were screened for the presence of anti-Toxoplasma IgG and IgM antibodies by enzyme-linked immunosorbent assay (ELISA). Only one sample recorded as IgM positive (0.98%) (1/102; 95% CI = 0.02- 5.34%), whereas 44.12% (45/102; 95% CI = 34.29-54.29%) were IgG positive. The study showed that seroprevalence of toxoplasmosis significantly differs between age groups (p < 0.001), with high prevalence of T. gondii infection (37.8%) among patients aged less than one month. Moreover, the study indicated a significant difference in the prevalence of toxoplasmosis between males and females. Additionally, a significant dependent relationships were observed (p = 0.003), when the reasons of toxoplasma serology request was considered, and the highest prevalence (59.6%) observed in congenital toxoplasmosis. In conclusion, the seroprevalence of toxoplasmosis in our study group was high. The study provides preliminary information about the seroprevalence and epidemiology of T. gondii infection among the hospital population in HUSM.
