Genomic characterization of SARS-CoV-2 from Uganda using MinION nanopore sequencing
In this study, we sequenced and characterized 49 SARS-CoV-2 samples from Uganda, collected between April 2020 and July 2021, using MinION Nanopore sequencing. Overall, the ARTIC protocol used was able to generate the required libraries for successful sequencing on the long-read sequencer. MinION Oxford Nanopore technology enabled the identification of…
Characteristics of Klebsiella pneumoniae co-infections
Introduction Tuberculosis (TB), caused by Mycobacterium tuberculosis (M. tuberculosis), is a prominent issue in the field of global public health, particularly in lower-middle-income-countries. Nearly two-thirds of global TB cases come from eight countries, including China.There are 780,000 new TB cases in China every year.1 TB is characterized by increased risk…

Clinical Evaluation of Metagenomic Next-Generation Sequencing and Iden
Introduction Infection is one of the major causes of death in patients with acute and critical illnesses. Especially, lower respiratory tract infections (LRTIs) are the most common infectious diseases worldwide, with a high mortality rate.1,2 As estimated, there are about 10 million new cases of LRTIs in China each year.3,4…
Cervical screening using HPV-DNA cytology in a low-income setting: an audit within a socio-economically deprived rural community in the Philippines
Cervical cancer (CC) is the fourth most diagnosed cancer and the fourth leading cause of cancer death among women globally.1 In the Philippines, CC is the second leading cause of cancer in women. In 2018 there were 9.1% new CC cases in the Philippines, compared to 0.47% new cases in…
Global DNA Polymerase Market Size, Trends, Demand, Forecast to 2031
DNA polymerase is a group of enzymes that speeds up DNA synthesis during replication. A cell’s DNA is duplicated during cell division. Nucleotides are added to the 3’OH group to digest the growing DNA strand. It is significant because it facilitates the transmission of genetic information from one generation to…
