Emergence of B.1.524(G) SARS-CoV-2 in Malaysia during the third COVID-19 epidemic wave.

The COVID-19 pandemic first emerged in Malaysia in Jan 2020. As of 12th Sept 2021, 1,979,698 COVID-19 cases that occurred over three major epidemic waves were confirmed. The virus contributing to the three epidemic waves has not been well-studied.

Replication Kinetics of in Tick Cell Lines.

is one of the causative agents of tick-borne lymphadenopathy in humans. This bacterium was previously isolated and propagated in tick cell lines; however, the growth characteristics have not been investigated. Here, we present the replication kinetics of in cell lines derived from different tick genera (BME/CTVM23, RSE/PILS35, and IDE8).

Detection and confirmation of dengue pre- and postintroduction of dengue NS1-antigen test at the University Malaya Medical Centre: An observational study.

Early diagnosis of dengue is important to ensure proper management of patients and effective implementation of control measures. The present study was undertaken to determine the outcome of the implementation of dengue NS1-antigen (Ag) rapid diagnostic test (RDT) in the confirmation of dengue at the first patient hospital visit at the University Malaya Medical Centre. A total of 1036 and 1097 sera from the year 2008 and 2015 were used, representing samples from before and after dengue NS1-Ag RDT was implemented as routine diagnostic at the hospital.

Isolation and Propagation of Laboratory Strains and a Novel Flea-Derived Field Strain of in Tick Cell Lines.

are intracellular endosymbionts of several invertebrate taxa, including insects and nematodes. Although DNA has been detected in ticks, its presence is generally associated with parasitism by insects. To determine whether or not can infect and grow in tick cells, cell lines from three tick species, , and , were inoculated with strains Stri and AlbB isolated from mosquito cell lines.
