Abstract Background Emerging fungal pathogens pose important threats to global public health. The World Health Organization has responded the rising threat of traditionally neglected infections by developing a Fungal Priority Pathogens List (FPPL). Taking highest-ranked pathogen in FPPL, Cryptococcus neoformans , as paradigm, we review progress made over past two decades on its burden, clinical manifestation and management cryptococcal infection, antifungal resistance. purpose this is drive research efforts improve future diagnoses, therapies, interventions associated with infections.

Abstract Background COVID-19 is known as a new viral infection. Viral-bacterial co-infections are one of the biggest medical concerns, resulting in increased mortality rates. To date, few studies have investigated bacterial superinfections patients. Hence, we designed current study on patients admitted to ICUs. Methods Nineteen our ICUs were enrolled this study. detect COVID-19, reverse transcription real-time polymerase chain reaction was performed. Endotracheal aspirate samples also collected and cultured different media support growth bacteria. After incubation, formed colonies identified using Gram staining other biochemical tests. Antimicrobial susceptibility testing carried out based CLSI recommendations. Results Of nineteen patients, 11 (58%) male 8 (42%) female, with mean age ~ 67 years old. The average ICU length stay 15 days at end study, 18 cases (95%) expired only 1 case (5%) discharged. In total, all found positive for infections, including seventeen Acinetobacter baumannii (90%) two Staphylococcus aureus (10%) strains. There no difference bacteria species detected any sampling points. Seventeen 17 strains resistant evaluated antibiotics. No metallo-beta-lactamases -producing strain found. One isolates methicillin-resistant isolated from patient who died, while another susceptible tested drugs methicillin-sensitive . Conclusions Our findings emphasize concern superinfection due Consequently, it important pay attention critical COVID-19.

Abstract Background It has been recognised for a considerable time-period, that viral respiratory infections predispose patients to bacterial infections, and these co-infections have worse outcome than either infection on its own. However, it is still unclear what exact roles and/or superinfections play in with COVID-19 infection. Main body This was an extensive review of the current literature regarding SARS-CoV-2 The definitions used were those Centers Disease Control Prevention (US), which defines coinfection as one occurring concurrently initial infection, while are follow previous especially when caused by microorganisms resistant, or become antibiotics earlier. Some researchers envisioned three potential scenarios bacterial/SARS-CoV-2 co-infection; namely, secondary following colonisation, combined viral/bacterial pneumonia, superinfection SARS-CoV-2. There myriad published articles ranging from letters editor systematic reviews meta-analyses describing varying ranges co-infection COVID-19. concomitant described included other viruses, bacteria, including mycobacteria, fungi, well other, more unusual, pathogens. will be seen this review, there often not clear distinction made authors referring to, whether true concomitant/co-infections superinfections. In addition, possible mechanisms interactions between SARS-CoV-2, particularly discussed further. Lastly, impact severity their also described. Conclusion describes rates although two literature. When they occur, appear associated both poorer outcomes.

The dissemination of COVID-19 around the globe has been followed by an increased consumption antibiotics. This is related to concern for bacterial superinfection in patients. identification pathogens challenging low and middle income countries (LMIC), as there are no readily-available cost-effective clinical or biological markers that can effectively discriminate between viral infections. Fortunately, faced with threat spread, a growing awareness importance antimicrobial stewardship programs, well infection prevention control measures could help reduce microbial load hence circulation pathogens, reduction resistance. These should be improved particularly developing countries. Studies need conducted evaluate worldwide evolution resistance during pandemic, because do not respect borders. issue takes on even greater countries, where data patterns scarce, conditions infectious pathogen transmission optimal, treatment resources suboptimal.
