-positive strains, ST-16 was the main type. Two main

variants KD (T112K, Y176D) and RDK (I104R, Y176D, E256K) slightly raised enterococci's MIC of linezolid.

OptrA exists in linezolid non-resistant enterococci with diverse amino acid substitutions. The variants play different roles in changing the MIC of linezolid.

One of the critical issues to be addressed is the improvement in laboratory diagnosis and screening of large portions of the population to stop the virus spreading. Currently, the laboratory diagnosis of SARS-CoV-2 infection and the related disease is based on the research of viral RNA with rt-PCR methods in upper and lower respiratory airways. Serological tests to detect SARS-CoV-2 antibodies could help physicians and healthcare workers to support COVID-19 diagnosis and follow-up and perform population screening. Our review, using MEDLINE and EMBASE, summarizes the current knowledge of direct and serological tests performed to research RNA, antigens, or antibodies for SARS-CoV-2, evaluating the advantages and drawbacks for specific tests.

Despite the worldwide spread of the coronavirus disease 2019 (COVID-19), the epidemiological and clinical patterns of the COVID-19 infection remain largely unclear, particularly among children. In this study, we explored the epidemiological characteristics, clinical patterns, and laboratory and imaging findings of pediatric patients with COVID-19.

From March 7 to March 30, 2020, there were a total of 35 patients who had confirmed COVID-19 infection by laboratory virus nucleic acid test (RT-PCR) assay with throat swab samples or typical chest CT manifestation compatible with COVID-19, in addition to a history of close contact with suspected or confirmed SARS-CoV-2 in family members. Information recorded included demographic data, medical history, exposure history, underlying comorbidities, symptoms, signs, laboratory findings and radiologic assessments, severity of disease, treatment, and mortality.

The median age of the patients was 7.5 years (IQR=4-11; range=4 months to 15 years). A total of 63% were mt was observed, early detection of children with COVID-19 infection by CT is conducive to reasonable management and early treatment.

Tuberculosis is a rare but life-threatening complication in patients who received hematopoietic stem cell transplantation. Early identification and intervention are essential to prevent severe complications.

We report two pediatric patients who developed tuberculosis after receiving hematopoietic stem cell transplantation for thalassemia major among 330 recipients between January 2012 and August 2019. Patient A presented with pulmonary tuberculosis and patient B presented with lymph node tuberculosis mimicking post-transplantation lymphoproliferative disorder associated with Epstein-Barr virus reactivation. Patient B's condition was deteriorated, and shortly after the initiation of anti-tuberculosis therapy, the patient was found to have disseminated pulmonary tuberculosis. Patient B was also found to have tuberculous granulomas, an uncommon manifestation of tuberculosis causing severe airway obstruction. Immunology activator Both patients developed critical respiratory failure and required mechanical ventilation; however, they recovered with almost full resolution of pulmonary lesions after multiple treatment adjustments.

Tuberculosis must be carefully evaluated in all pediatric patients that receive hematopoietic stem cell transplantation, regardless of the identification of other pathogens. Prophylactic tuberculosis therapy should be considered for high-risk pediatric hematopoietic stem cell transplantation recipients from tuberculosis-endemic regions.

Forty-four COVID-19 patients (severe/critical N = 8, non-severe N = 36) were examined by next generation sequencing (NGS) of nasopharyngeal test paper to observe the effect of novel coronavirus infection to the microbial composition in upper airway.

In these nasopharyngeal test paper samples, 38 kinds of bacteria, 10 kinds of viruses except

, nine kinds of fungi and three kinds of atypical pathogens had been found. There was some difference in microbial composition in the upper airway between severe and non-severe cases.

These results are important for us to study the effect of

on the local microbial composition of upper airway and prevent opportunistic infection in severe patients.

The purpose of this study was to identify the common clinical presentations and the evidence on the presence of ageusia and anosmia as an emerging coronavirus disease 2019 (COVID-19) symptom to better inform in both COVID-19 patients and clinicians.

As part of a double-institutional collaboration coordinated by doctors, this study retrospectively collected and analyzed the clinical characteristics of 60 patients with COVID-19 pneumonia between April 1 and April 20, 2020. Pregnant women and patients taking anti-cancer drugs had been excluded from the study. Data from each institution's electronic medical record had been obtained.

Sixty patients who had RT-PCR positive for COVID-19 were included in this study; of these patients, all of them had unknown exposure to COVID-19. The mean (SD) age was 45.7 (13.5) years, and 42 were men (70%). Of these patients, 80% had at least ageusia or anosmia. The most common symptoms at the onset of illness were cough (75%), fever (71.3%), myalgia or fatigue (53.3%), anosmia (loss of smell) (40%), ageusia (loss of taste) (28.
