Malaria rapid diagnostic tests had poor performance in P. malariae diagnosis and may threaten the prevention of malaria re-establishment from returned travellers in China, finds a study published in the MalariaJournal.
Considering past malaria epidemic patterns, whether RDTs are useful in diagnosing importedcases were analysed and the sensitivity of five RDTs in detectingto identify the ideal diagnostic methods was evaluated, which can be applied in the POR of malaria. Moreover, the factors that influenced the results of RDTs in the detection ofImported malaria cases in China and Jiangsu Province from 2013 to 2020 were analysed.
The age, sex and origin country distributions of the reported imported malaria cases were collected and analysed, and the duration between patients’ return to China to symptom onset and symptom onset to first medical facility visit were analysed.Clinic attendees with fever symptoms were tested for malaria by either microscopy examination or a RDT; both methods were used in medical facilities at the county and above levels.

The future of CRISPR in Mycobacterium tuberculosis infection - Journal of Biomedical ScienceClustered Regularly Interspaced Short Palindromic repeats (CRISPR)-Cas systems rapidly raised from a bacterial genetic curiosity to the most popular tool for genetic modifications which revolutionized the study of microbial physiology. Due to the highly conserved nature of the CRISPR locus in Mycobacterium tuberculosis, the etiological agent of one of the deadliest infectious diseases globally, initially, little attention was paid to its CRISPR locus, other than as a phylogenetic marker. Recent research shows that M. tuberculosis has a partially functional Type III CRISPR, which provides a defense mechanism against foreign genetic elements mediated by the ancillary RNAse Csm6. With the advent of CRISPR-Cas based gene edition technologies, our possibilities to explore the biology of M. tuberculosis and its interaction with the host immune system are boosted. CRISPR-based diagnostic methods can lower the detection threshold to femtomolar levels, which could contribute to the diagnosis of the still elusive paucibacillary and extrapulmonary tuberculosis cases. In addition, one-pot and point-of-care tests are under development, and future challenges are discussed. We present in this literature review the potential and actual impact of CRISPR-Cas research on human tuberculosis understanding and management. Altogether, the CRISPR-revolution will revitalize the fight against tuberculosis with more research and technological developments.
