Building Research Capacity In Low- And Middle-Income Countries And Pandemic Preparedness: Lessons Learned And Future Directions, Peter H. Kilmarx, Karen A. Goralesk, Erum Khan, John F. Lindo, Nancy Gore Saravia
Building Research Capacity In Low- And Middle-Income Countries And Pandemic Preparedness: Lessons Learned And Future Directions, Peter H. Kilmarx, Karen A. Goralesk, Erum Khan, John F. Lindo, Nancy Gore Saravia

Research capacity is a critical component of pandemic preparedness, as highlighted by the challenges faced during the Ebola outbreak in West Africa. Recent global initiatives, such as the Research & Development Task Force of the Global Health Security Agenda and the World Health Assembly's resolution on strengthening clinical trials, emphasize the need for robust research capabilities. This Perspective discusses the experiences of leaders in infectious disease research and capacity building in low- and middle-income countries, focusing on Colombia, Jamaica, and Pakistan. These case studies underscore the importance of collaborative efforts, interdisciplinary training, and global partnerships in pandemic response. The experiences …
Drug-Resistant Bacterial Infections: We Need Urgent Action And Investment That Focus On The Weakest Link, Christiane Dolecek, Sadia Shakoor, Buddha Basnyat, Tochi Okwor, Benn Sartorius

Despite high mortality and morbidity, drug-resistant bacterial infections remain the forgotten pandemic. We argue for strengthening of diagnostics, WASH (water, sanitation, and hygiene) and infection prevention and control to reduce drug-resistant infections, as an integral part of sustainable high-quality health services, particularly in low- and middle-income countries.
Emergence Of A Multidrug-Resistant And Virulent Streptococcus Pneumoniae Lineage Mediates Serotype Replacement After Pcv13: An International Whole-Genome Sequencing Study, Stephanie W.

Background: Serotype 24F is one of the emerging pneumococcal serotypes after the introduction of pneumococcal conjugate vaccine (PCV). We aimed to identify lineages driving the increase of serotype 24F in France and place these findings into a global context.
Methods: Whole-genome sequencing was performed on a collection of serotype 24F pneumococci from asymptomatic colonisation (n=229) and invasive disease (n=190) isolates among individuals younger than 18 years in France, from 2003 to 2018. To provide a global context, we included an additional collection of 24F isolates in the Global Pneumococcal Sequencing (GPS) project database for analysis. A Global Pneumococcal Sequence Cluster …
Chloroquine-Susceptible And -Resistant Plasmodium Falciparum Strains Survive High Chloroquine Concentrations By Becoming Dormant But Are Eliminated By Prolonged Exposure, Johan Ursing, Rasmus Johns, Berit Aydin-Schmidt, Carla Calçada, Poul-Erik Kofoed, Najia Karim Ghanchi, Maria Isabel Veiga, Lars Rombo

Background: Plasmodium falciparum strains that are resistant to standard-dose chloroquine can be treated by higher chloroquine concentrations maintained for a longer time in vivo.
Objectives: To determine the relative importance of chloroquine concentrations versus exposure time for elimination of chloroquine-susceptible and -resistant P. falciparum in vitro.
Methods: Chloroquine-susceptible (3D7) and -resistant (FCR3) strains were exposed in vitro to 1, 2, 4, 8, 16 or 32 times their respective 90% inhibitory chloroquine concentrations for 3, 5, 7 or 14 days and then followed until recrudescence, or not, by 42 days after the end of exposure.
Results: Exposure to chloroquine appeared to …

Background: Mutations in the Rv0678, pepQ and atpE genes of Mycobacterium tuberculosis (MTB) have been reported to be associated with reduced antimycobacterial susceptibility to bedaquiline (BDQ). Resistance conferring mutations in treatment naïve MTB strains is likely to have implications for BDQ based new drug regimen that aim to shorten treatment duration. We therefore investigated the genetic basis of resistance to BDQ in MTB clinical isolates from BDQ naïve TB patients from Pakistan. In addition, mutations in genes associated with efflux pumps were investigated as an alternate mechanism of resistance.
Methods: Based on convenience sampling, we studied 48 MTB clinical isolates …

Non-tuberculous mycobacteria (NTM) are ubiquitous dwellers of environmental niches and are an established cause of natural and nosocomial infections. The incidence of NTM infections is rising owing to a growing population of immunocompromised and vulnerable individuals, complex medical and surgical procedures, as well as increased awareness and diagnostic capabilities. The prevalence of different NTM varies between continents, regions, and countries. The true global burden of pulmonary and extrapulmonary disease is unknown and estimates are subject to under and/or over-estimation. Diagnosis requires confirmation by isolation of NTM along with clinical and radiological criteria, which may be suboptimal at all levels. Susceptibility …
