Detection of novel tick-borne pathogen, Alongshan virus, in Ixodes ricinus ticks, south-eastern Finland, 2019The newly identified tick-borne Alongshan virus (ALSV), a segmented Jingmen virus group flavivirus, was recently associated with human disease in China. We report the detection of ALSV RNA in Ixodes ricinus ticks in south-eastern Finland. Screening of sera from patients suspected for tick-borne encephalitis for Jingmen tick virus-like virus RNA and antibodies revealed no human cases. The presence of ALSV in common European ticks warrants further investigations on its role as a human pathogen.
Added Value of Xpert MTB/RIF Ultra for Diagnosis of Pulmonary Tuberculosis in a Low-Prevalence SettingOnya Opota, Fathiah Zakham, Jesica Mazza‐Stalder et al.|Journal of Clinical Microbiology|2018 = 196) in Lausanne (Switzerland). Clinical data were used to investigate discrepant results. Correlation between semiquantitative result of Ultra and smear microscopy status for the detection of acid-fast bacilli (AFB) was established. The sensitivities of Xpert and Ultra were 82.9% (39/47) and 95.8% (45/47), respectively, when considering all culture-positive specimens, 100% (23/23) for both assays on smear-positive specimens, and 66.7% (16/24) and 91.7% (22/24) on smear-negative specimens. Using culture as gold standard, the specificities of Xpert and Ultra were 97.3% (145/149) and 96.64% (144/149), respectively. All the patients with Ultra-positive results with the new category "trace" were diagnosed with active TB based on clinical findings and microbiological culture. The semiquantitative results of both Xpert and of Ultra positively correlated with the semiquantitative result of AFB detection. Our data support an increased sensitivity of Ultra compared to Xpert in a low-prevalence setting. Correlation between the Ultra semiquantitative result and AFB burden can help in evaluating a patient's transmission potential.
Viral RNA Metagenomics of Hyalomma Ticks Collected from Dromedary Camels in Makkah Province, Saudi ArabiaArthropod-borne infections are a medical and economic threat to humans and livestock. Over the last three decades, several unprecedented viral outbreaks have been recorded in the Western part of the Arabian Peninsula. However, little is known about the circulation and diversity of arthropod-borne viruses in this region. To prepare for new outbreaks of vector-borne diseases, it is important to detect which viruses circulate in each vector population. In this study, we used a metagenomics approach to characterize the RNA virome of ticks infesting dromedary camels (Camelus dromedaries) in Makkah province, Saudi Arabia. Two hundred ticks of species Hyalomma dromedarii (n = 196) and Hyalomma impeltatum (n = 4) were collected from the Alkhurma district in Jeddah and Al-Taif city. Virome analysis showed the presence of several tick-specific viruses and tick-borne viruses associated with severe illness in humans. Some were identified for the first time in the Arabian Peninsula. The human disease-associated viruses detected included Crimean Congo Hemorrhagic fever virus and Tamdy virus (family Nairoviridae), Guertu virus (family Phenuiviridae), and a novel coltivirus that shares similarities with Tarumizu virus, Tai forest reovirus and Kundal virus (family Reoviridae). Furthermore, Alkhurma hemorrhagic virus (Flaviviridae) was detected in two tick pools by specific qPCR. In addition, tick-specific viruses in families Phenuiviridae (phleboviruses), Iflaviridae, Chuviridae, Totiviridae and Flaviviridae (Pestivirus) were detected. The presence of human pathogenetic viruses warrants further efforts in tick surveillance, xenosurveillence, vector control, and sero-epidemiological investigations in human and animal populations to predict, contain and mitigate future outbreaks in the region.
Challenges and coping strategies faced by female scientists—A multicentric cross sectional studyWomen can play a pivotal role in the progress and sustainability of the world if they are empowered through education and employment opportunities in Science, technology, innovation and through changing the social stereotypes that restrain them in certain workplaces. In the literature, few recently published studies exist that document the challenges faced by female scientists in their workplaces. The purpose of this study was to understand the challenges and coping strategies faced by female scientists around the world today, in order to contribute to their improved performance. A multi-centre electronic cross-sectional survey across 55 countries was conducted to profile female scientists and to identify the challenges that they experience throughout their career as well as the coping mechanisms that they use to overcome the barriers. A total of 263 female scientists from different countries across the world participated in our study and most participants were from the South East Asian Region. Most female scientists in our study belong to the middle and junior level career category and earning around 1250 USD per month. Most of the scientists reported availability of maternity leave at their workplace but less than a third reported presence of a creche at work. Workplace sexual harassment was reported by 24% of the study population. Work related stress (71.5%) and work life imbalance (46%) are also major challenges faced by female scientists. Self-confidence, dedication and hard work are the most commonly adopted coping strategy. Flexible work timings, woman-friendly management policies, fair appraisal and mentorship appear to reduce the work-related stress and improve work-life balance among female scientists. In conclusion, female scientists face numerous challenges, which can greatly affect both their individual and career growth. Intrinsic (personal) and extrinsic (institutional) factors are important for improving female scientists' wellbeing and productivity.
