False-negative cerebral spinal fluid cryptococcal antigen lateral flow assay due to postzone phenomenon in a patient with disseminated cryptococcal disease: a case report.

This report presents the case of false-negative cerebral spinal fluid (CSF) cryptococcal antigen (CrAg) lateral flow assay (LFA) in a HIV-positive 25-year-old male. The patient presented with headache, nausea and vomiting for 5 days and syncope for 1 day. An initial CSF CrAg LFA test was negative, but a 1:4 dilution of the CSF was weakly positive and a 1:8 dilution was positive.

Clinical features of patients with talaromycosis marneffei and microbiological characteristics of the causative strains.

Background: Talaromyces marneffei (T. marneffei) is a temperature-dependent dimorphic fungus that is mainly prevalent in Southeast Asia and South China and often causes disseminated life-threatening infections. This study aimed to investigate the clinical features and improve the early diagnosis of talaromycosis marneffei in nonendemic areas.

infection in a patient with diffuse large B-cell lymphoma and haemophagocytic syndrome: A case report and literature review.

Although uncommon, infection caused by may be life threatening particularly in immunocompromised patients. We report here a rare presentation of a patient with diffuse large B-cell lymphoma and haemophagocytic syndrome associated with bacteraemia. The management of the patient is described as well as a review of medical literature.

Antibiotic Resistance Determinants and Virulence Factors of Hypervirulent and Carbapenem Non-Susceptible Pseudomonas aeruginosa.

Background: The aim was to investigate the distribution of antibiotic resistance determinants and virulence factors in a group of carbapenem non-susceptible Pseudomonas aeruginosa (P. aeruginosa).

Methods: From March 2018 to May 2019, a total of 98 P.

Eikenella corrodens infections in human: Reports of six cases and review of literatures.

Purpose: To investigate clinical characteristics of six cases of Eikenella corrodens infection in Ningbo First Hospital in China in recent 2 years.

Methods: We retrospectively analyze medical records of six cases of E. corrodens infection in Ningbo First Hospital from 2020 to 2021.

Clinical and Microbiological Characteristics of a Community-Acquired Carbapenem-Resistant ST410 Isolate Harbouring NDM-5-Encoding IncX3-Type Plasmid From Blood.

The aim of this research was to investigate the clinical and microbiological characteristics of a case of community-acquired carbapenem-resistant isolated from a patient with a bloodstream infection in China. Huamei202001 was recovered from the first blood culture from a patient hospitalised in China. An antimicrobial susceptibility test was performed, and the genome was sequenced on an Illumina HiSeq X 10 platform with a 150-bp paired-end approach.

Differential diagnosis of coronavirus disease 2019 pneumonia or influenza A pneumonia by clinical characteristics and laboratory findings.

Background: Pneumonia caused by the 2019 novel Coronavirus (COVID-2019) shares overlapping signs and symptoms, laboratory findings, imaging features with influenza A pneumonia. We aimed to identify their clinical characteristics to help early diagnosis.

Methods: We retrospectively retrieved data for laboratory-confirmed patients admitted with COVID-19-induced or influenza A-induced pneumonia from electronic medical records in Ningbo First Hospital, China.

Dynamic change process of target genes by RT-PCR testing of SARS-Cov-2 during the course of a Coronavirus Disease 2019 patient.

We report the dynamic change process of target genes by RT-PCR testing of SARS-Cov-2 during the course of a COVID-19 patient: from successive negative results to successive single positive nucleocapsid gene, to two positive target genes (orf1ab and nucleocapsid) by RT-PCR testing of SARS-Cov-2, and describe the diagnosis, clinical course, and management of the case. In this case, negative results of RT-PCR testing was not excluded to diagnose a suspected COVID-19 patient, clinical signs and symptoms, other laboratory findings, and chest CT images should be taken into account for the absence of enough positive evidence. This case highlights the importance of successive sampling and testing SARS-Cov-2 by RT-PCR as well as the increased value of single positive target gene from pending to positive in two specimens to diagnose laboratory-confirmed COVID-19.

Investigation of antibiotic resistance determinants and virulence factors of uropathogenic Escherichia coli.

Multidrug-resistant (MDR) uropathogenic Escherichia coli (UPEC) are prevalent throughout the world resulting in a major public health burden. In this research, we isolated and identified 28 MDR UPEC from one university hospital in China, investigated MDR and pathogenic mechanisms by PCR, including 55 antibiotic resistance determinants (ARDs) genes, 13 genetic markers of mobile genetic elements (MGEs) and 6 virulence factors (VFs) genes. In these isolates, we identified 23 ARDs genes and 6 genetic markers of MGEs that played a key role in MDR phenotypes.

Draft Genome Sequence of a Klebsiella pneumoniae Strain (New Sequence Type 2357) Carrying Tn3926.

We present the draft genome sequence of a Klebsiella pneumoniae carbapenemase-producing sequence type 2357 (ST2357) strain, NB60, which contains drug-resistant genes encoding resistance to beta-lactams, fluoroquinolones, aminoglycosides, trimethoprim-sulfamethoxazole, colistin, macrolides, and tetracycline. Strain NB60 was isolated from human blood, making it an important tool for studying K. pneumoniae pathogenesis.

Draft Genome Sequence of Uropathogenic Escherichia coli Strain NB8.

Escherichia coli NB8 is a clinical pyelonephritis isolate. Here, we report the draft genome sequence of uropathogenic E. coli NB8, which contains drug resistance genes encoding resistance to beta-lactams, aminoglycosides, quinolones, macrolides, colistin, sulfonamide-trimethoprim, and tetracycline.

Antibiotic resistance determinants of a group of multidrug-resistant Acinetobacter baumannii in China.

A group of Acinetobacter baumannii confers multidrug resistance, but the molecular epidemiology and multidrug resistance mechanisms are poorly understood. Nineteen isolates were identified, and the antimicrobial susceptibility profile was determined using the disc diffusion method. Then, PCR of 78 kinds of resistance-associated genes were performed.
