Project description:Although Bordetella hinzii coccobacilli is most commonly identified in respiratory tracts of birds and rodents, this organism has occasionally been isolated in human infections. We describe a case of B. hinzii spontaneous bacterial peritonitis in Missouri, USA. Whole-genome sequencing of blood and peritoneal fluid isolates confirmed B. hinzii infection.

Bordetella hinzii Pneumonia in Patient with SARS-CoV-2 Infection.

Project description:Patients infected with severe acute respiratory syndrome coronavirus 2 might have bacterial and fungal superinfections develop. We describe a clinical case of coronavirus disease with pulmonary aspergillosis associated with Bordetella hinzii pneumonia in an immunocompetent patient in France. B. hinzii infections are rare in humans and develop secondary to immunosuppression or debilitating diseases.

Bordetella hinzii Pneumonia and Bacteremia in a Patient with SARS-CoV-2 Infection.

Project description:Patients with severe acute respiratory syndrome coronavirus 2 infection may have bacterial co-infections, including pneumonia and bacteremia. Bordetella hinzii infections are rare, may be associated with exposure to poultry, and have been reported mostly among immunocompromised patients. We describe B. hinzii pneumonia and bacteremia in a severe acute respiratory syndrome coronavirus 2 patient.

The first case of Acrophialophora levis-induced severe pneumonia: a case report and literature review.

Project description:BackgroundIn recent years, some rare fungi have been increasingly recognized as new human pathogens. Here we reported the first fatal case of human severe pneumonia complicated by multiple organ dysfunction caused by Acrophialophora levis infection. However, its pathogenic mechanism and risk factors are unknown. Acrophialophora genus has only reported in six cases of human infection worldwide, but it has not been reported previously in China.Case presentationA 71-year-old male patient with severe pneumonia complicated with multiple organ dysfunction caused by A. levis infection. The fungal identification was based on micromorphology and sequence analysis of the internal transcriptional spacer (ITS) of ribosomal RNA genes recovered from lower respiratory tract secretions. The microbial characteristics, sensitivity to antifungal drugs of this isolated A. levis were studied. Anti-infective regimen, liposomal amphotericin B combined with tegacycline, was used to prevent infection. The next day, the fever decreased, body temperature fluctuated between 36.5 and 37.8 degree, cough and sputum decreased, and sputum volume decreased, with oxygen uptake for 5 L/min, blood oxygen saturation over 95%. After 17 days of treatment, CT reexamination showed that the lesions in the right lung and left upper lung were absorbed and pleural effusion was reduced. The next 8 days, the patient asked to return to the local hospital for treatment. The local hospital stopped using liposomal amphotericin B because of the absence of liposomal amphotericin B, and died of respiratory failure 2 days later.ConclusionsThis study is the first to report the occurrence, risk factors, molecular determinants, microbial characteristics and susceptibility to antifungal agents of A. levis infection in China. In addition, six published cases of human infection with Acrophialophora were reviewed.

Exogenous lipid pneumonia in old people caused by aspiration: Two case reports and literature review.

Project description:BackgroundExogenous lipoid pneumonia is a rare entity, the diagnosis is often missed or delayed.ObjectiveTo investigate the clinical characteristics of exogenous lipid pneumonia in elderly patients, improve the efficiency of early diagnosis and treatment of this disease.MethodsRetrospectively analyzed the clinical information and imaging data of these 2 exogenous lipid pneumonia patients, reviewed related literature.ResultsBoth of the 2 patients were over 60 with a history of gastrointestinal diseases. The clinical presentation is nonspecific. Chest CT showed many different manifestations. Histopathology analysis revealed the accumulation of lipid carrying macrophages, vacuolar cells and inflammation. A literature review indicated that 25 previous cases of exogenous lipid pneumonia were caused by aspiration. The most common site of the lesion was located in right lung, while mineral oil was the most common substances. We sought to discuss the patient's treatment and the corresponding outcomes.ConclusionThe diagnosis of lipid pneumonia's mainly depends on medical history and histopathological morphology. The standard treatment for exogenous lipid pneumonia was composed of antibiotics, steroid, bronchoscopic lavage and a regular follow-up.

First human case of catheter-related blood stream infection caused by Staphylococcus schleiferi subspecies coagulans: a case report and literature review.

Project description:BackgroundStaphylococcus schleiferi is a gram-positive pathogenic coccus which causes canine skin and ear infections. Only four cases of human infection caused by Staphylococcus schleiferi subspecies coagulans have been reported. Herein, we present the first case of catheter-related bloodstream infection caused by S. schleiferi subspecies coagulans.Case presentationA 62-year-old Japanese man was admitted to our hospital for examination of sigmoid colon tumor. During hospitalization, he had fever, shaking chills, and swelling at the peripheral venous catheter insertion site. Two sets of blood cultures were positive for S. schleiferi subspecies coagulans which was confirmed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), 16S ribosomal RNA sequencing and the coagulase test. The patient was successfully treated without relapse.ConclusionTo our knowledge, this is the first report of catheter-related bloodstream infection caused by S. schleiferi subspecies coagulans. S. schleiferi subsp. coagulans can be pathogenic in humans, and MALDI-TOF MS can contribute to accurate identification of S. schleiferi subspecies coagulans.
