Rhizopus homothallicus, an emerging pathogen causing cavitary lung lesions.

ABSTRACT:

Introduction

Rhizopus homothallicus is an emerging pathogen that causes pulmonary mucormycosis.

Case presentation

We report a case of pneumonia caused by R. homothallicus in a 54-year-old type 2 diabetic patient. The organism was isolated from bronchoalveolar lavage fluid and preliminarily identified by fungal morphology and finally by sequencing of the internal transcribed spacer region.

Conclusion

Mucormycosis may be associated with cavitary lung lesions against a backdrop of poorly controlled diabetes or other immunosuppressed states. Pulmonary mucormycosis may have variable clinical and radiological presentations. Therefore, strong clinical suspicion and prompt management can address the high fatality associated with the disease.

Cavitary lung lesions: Melioidosis and pulmonary embolism causing necrotizing pneumonia.

Project description:Cavitary lung lesions of various etiologies may be encountered in patients with respiratory symptoms associated with fever. Non-malignant cavitary lesions may mimic malignant lung lesions on most of radiographic modalities including chest radiographs or thoracic computed tomography (CT). Primary lung malignancy can be detected in as high as one-fifths of CT thorax as cavitary lesions and the remaining aetiologies may be due to bacterial, parasitic, and invasive fungal infections, as well as Granulomatosis with polyangiitis (GPA), sarcoidosis, septic thrombo-embolism, and lung metastasis from extra-pulmonary primaries. We report an interesting case of melioidosis infection complicated with pulmonary embolism, both of which can lead to cavitary lung lesions and subsequently cause a clinical conundrum.

Cavitary lung lesions and pneumothorax in a healthy patient with active coronavirus-19 (COVID-19) viral pneumonia.

Project description:Severe respiratory sequelae drive morbidity-associated with coronavirus 2019 (COVID-19) disease. We report a case of COVID-19 pneumonia complicated by cavitary lesions and pneumothorax in a young healthy male. Pneumothorax management with catheter thoracostomy and rapid resolution of the cavitary lesions are described. An extensive work-up for other causes a cavitation was negative and the temporal correlation of the cavities with COVID-19 infection plus their rapid resolution suggest a direct relationship. We propose a mechanism for cavitation secondary to microangiopathy, a cause of cavitation in the vasculitides and a known feature of COVID-19.

Diffuse interstitial and multiple cavitary lung lesions due to Talaromyces marneffei infection in a non-HIV patient.

Project description:A 57-year-old man presented with unproductive cough and dyspnea for 6 months in Fujian Province, China. His misuse of a large amount of steroids (accumulated dose equivalent to 3530 mg prednisolone) resulted in Talaromyces marneffei infection. Chest computed tomographic scan revealed diffuse interstitial and multiple cavitary lung lesions. Treatment with amphotericin B combined with itraconazole resulted in total recovery, with marked regression of lung lesions.

Mycobacterium heckeshornense sp. nov., A new pathogenic slowly growing Mycobacterium sp. Causing cavitary lung disease in an immunocompetent patient.

Project description:A pathogenic scotochromogenic Mycobacterium xenopi-like organism was isolated from the lung of an immunocompetent young woman. This pathogen caused severe bilateral cavitary lung disease, making two surgical interventions necessary after years of chronic disease. This case prompted us to characterize this mycobacterium by a polyphasic taxonomic approach. The isolate contained chemotaxonomic markers which were typical for the genus Mycobacterium, i.e., the meso isomer of 2,6-diaminopimelic acid, arabinose, and galactose as diagnostic whole-cell sugars, MK-9(H(2)) as the principal isoprenoid quinone, a mycolic acid pattern of alpha-mycolates, ketomycolates, and wax ester mycolates, unbranched saturated and unsaturated fatty acids plus a significant amount of tuberculostearic acid, and small amounts of a C(20:0) secondary alcohol. On the basis of its unique 16S rRNA and 16S-23S spacer gene sequences, we propose that the isolate should be assigned to a new species, Mycobacterium heckeshornense. This novel species is phylogenetically closely related to M. xenopi. The type strain of M. heckeshornense is strain S369 (DSM 44428(T)). The GenBank accession number of the 16S rRNA gene of M. heckeshornense is AF174290.

<i>Streptococcus parasanguinis</i>: An emerging pathogen causing neonatal endocarditis: A case report.

Project description:Background. The microbial infection of the endocardium, popularly known as Infective Endocarditis (IE), is typically classified on the basis of anatomy, valve nativity and its associated microbiology. As per the associated microbiology, Staphylococcus aureus is the most common microorganism responsible for the cause of IE. Even though, the Streptococcus group accounts for a smaller percentage of IE, however this doesn't give us the liberty of ignoring the high mortality and morbidity associated with this pathogen. Case presentation. We report an unusual case of neonatal sepsis, complicated with endocarditis, caused by penicillin resistant Streptococcus parasanguinis . The neonate however died of the same despite all efforts. The said baby was given birth by a mother with gestational diabetes mellitus.ConclusionHigh index of clinical suspicion and prompt diagnosis are the most important factors of patient management, especially in cases of life threatening neonatal infections. In such conditions a coordinated interdepartmental approach is very much needed.

Cavitary lung metastasis as relapse of prostate cancer.

Project description:Prostate cancer is the most common non-cutaneous malignancy diagnosed in men. It usually metastasizes to bone as osteoblastic lesions on radiographs and regional lymph nodes, and uncommonly to lung, liver and brain. Metastatic prostate cancer recurrence after definitive local therapy can occur in any tissue. The role of fine needle aspiration cytology (FNAC) for diagnosis of metastatic malignancies is well established in literature. We describe a 74 years old male, previously treated for localized prostate cancer, admitted to our Department after total body computed tomography revealed multiple irregular lung lesions some of which had an excavated appearance.

Clinical and Mycologic Characteristics of Emerging Mucormycosis Agent Rhizopus homothallicus.

Project description:We retrospectively reviewed consecutive cases of mucormycosis reported from a tertiary-care center in India to determine the clinical and mycologic characteristics of emerging Rhizopus homothallicus fungus. The objectives were ascertaining the proportion of R. homothallicus infection and the 30-day mortality rate in rhino-orbital mucormycosis attributable to R. homothallicus compared with R. arrhizus. R. homothallicus accounted for 43 (6.8%) of the 631 cases of mucormycosis. R. homothallicus infection was independently associated with better survival (odds ratio [OR] 0.08 [95% CI 0.02-0.36]; p = 0.001) than for R. arrhizus infection (4/41 [9.8%] vs. 104/266 [39.1%]) after adjusting for age, intracranial involvement, and surgery. We also performed antifungal-susceptibility testing, which indicated a low range of MICs for R. homothallicus against the commonly used antifungals (amphotericin B [0.03-16], itraconazole [0.03-16], posaconazole [0.03-8], and isavuconazole [0.03-16]). 18S gene sequencing and amplified length polymorphism analysis revealed distinct clustering of R. homothallicus.

New Record of <i>Bipolaris cynodontis</i>: An Emerging Human Pathogen Causing Superficial Mycosis in North India.

Project description:Superficial mycosis, a common fungal infection affecting people worldwide are prevalent in the tropical and subtropical countries, mostly caused by the dermatophytes but nowadays, there is an increase in the incidence of these infections being caused by non-dermatophytic fungi and yeasts. Among non-dermatophytes, Bipolaris species, usually known to cause diseases in plants, have also emerged as potent human pathogens in the past years. Reports on Bipolaris species associated with clinical human skin samples are rare worldwide with no reports on B. cynodontis as a causal agent of superficial human skin mycoses from India. We report the first case of superficial mycosis caused by B. cynodontis that affected the feet of a 19-year-old female student from Jammu district, Jammu and Kashmir, India. Thus, the causal agent described in the research communication constitutes a new addition to the list of pathogenic non-dermatophytes associated with human skin.
