Background:
Coronavirus disease 2019 (COVID-19) has been associated with invasive fungal infection. Several COVID-19 cases were complicated due to coinfection with Aspergillus, Rhizopus, and Mucor species. We present COVID-19 with Aspergillus tubingensis coinfection.
Case Presentation:
A male patient presented with fever, cough, severe shortness of breath, and abdominal pain that persisted for a week. The patient was admitted to the ICU. The patient was diabetic and hypertensive, and COVID-19 pneumonia was confirmed. The patient became septic, and his blood culture was positive for Candida albicans. His sputum culture was positive for Acinetobacter spp. The patient was treated with a broad range of antibiotics and antifungal treatment. His case was complicated by hospital-acquired pneumonia; sputum culture was positive for Aspergillus species. Immediately, he developed septic shock, acute kidney injury, and disseminated intravascular coagulation (DIC). Postmortem molecular identification via ITS sequencing confirmed the presence of Aspergillus tubingensis.
Conclusions:
Invasive fungal infections are characterized by high mortality. Early diagnosis to the species level is essential for successful treatment.
Insights
This case study highlights a rare coinfection of COVID-19 with Aspergillus tubingensis. Early species-level diagnosis is crucial for managing invasive fungal infections in critically ill patients.
Area of Science:
- Mycology
- Infectious Diseases
- Critical Care Medicine
Background:
- Coronavirus disease 2019 (COVID-19) is increasingly associated with invasive fungal infections.
- Coinfections with Aspergillus, Rhizopus, and Mucor species have been reported in COVID-19 patients.
- This report details a unique case of COVID-19 with Aspergillus tubingensis coinfection.
Purpose of the Study:
- To present a case of coinfection between COVID-19 and Aspergillus tubingensis.
- To emphasize the importance of accurate species-level identification of fungal pathogens.
- To highlight the challenges in diagnosing and treating invasive fungal infections in the context of COVID-19.
Main Methods:
- A case presentation of a male patient with severe COVID-19 pneumonia.
- Inclusion of patient's comorbidities (diabetes, hypertension) and clinical course.
- Postmortem molecular identification using ITS sequencing for fungal pathogen confirmation.
Main Results:
- The patient presented with severe symptoms including fever, cough, shortness of breath, and abdominal pain.
- Complications included sepsis, hospital-acquired pneumonia, septic shock, acute kidney injury, and disseminated intravascular coagulation.
- Postmortem analysis confirmed Aspergillus tubingensis as the causative fungal agent.
Conclusions:
- Invasive fungal infections carry a high mortality rate.
- Prompt and accurate species-level diagnosis is essential for effective treatment strategies.
- This case underscores the need for vigilance regarding fungal coinfections in severe COVID-19 cases.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
