Mucormycoses are opportunistic fungal infections with a high mortality rate. Rhizopus oryzae is the most common agent implicated in human infections. Although R. homothallicus has been previously reported to be a cause of pulmonary mucormycosis, it is the first time that we are reporting as a causative agent of rhino-orbital and cutaneous mucormycosis.

Mucor and Rhizopus cause life-threatening infections primarily involving the lungs and sinuses, which disseminate very rapidly by necrosis and infarction of the contiguous tissues. We present a case of a 64-year-old African American posttransplant patient who presented with a productive cough and weight loss. He had a past surgical history of renal transplant for renal cell carcinoma and was on dual immunosuppressive therapy, that is, mycophenolate and tacrolimus. During his hospital stay, he developed a pneumopericardium due to the direct extension of a lung lesion...

We studied 19 cases of proven/probable mucormycosis diagnosed from 2007 to 2015 in our hospital and assessed the microbiological characteristics of the isolates. We recorded the incidence of mucormycosis and clinical and microbiological data of infected patients. Isolates were identified to molecular level and tested for their antifungal susceptibility to azoles, amphotericin B, and liposomal amphotericin B according to the CLSI M-38 A2 procedure. The incidence of mucormycosis in cases/100,000 hospital admissions during 2007-2015 increased significantly with respect to that reported in 1988-2006 (3...

Multiple animal models have been developed to study the pathogenesis of invasive pulmonary aspergillosis, as well as to evaluate the efficacy, pharmacokinetics, and pharmacodynamics of various antifungal agents and vaccines. Each model is beneficial depending on the questions that are asked. In this chapter, we will discuss the endpoints assessment of the persistently neutropenic rabbit models of invasive pulmonary aspergillosis and invasive pulmonary mucormycosis.

Mucormycosis is a life threatening infection caused by fungi in the order Mucorales. Mucormycosis can affect any organ system with rhino-orbital-cerebral and pulmonary infections being the most predominant infection types. Gastrointestinal mucormycosis is rare and accounts for only 4-7% of all cases. Here, we present a case of invasive gastrointestinal mucormycosis in an immunocompromised host treated with systemic and topical anti-mold therapy.

Infection caused by Cunninghamella bertholletiae carries one of the highest mortality rates among mucormycosis, and there are no reported cases that survived from the infection in allogeneic hematopoietic stem cell transplantation recipients occurring before neutrophil engraftment. Here, we present two cases of pulmonary mucormycosis caused by C. bertholletiae occurring before neutrophil engraftment after cord blood transplantation. Both were successfully treated with high-dose liposomal amphotericin B (10 mg/kg/day) combined with micafungin, which was then followed by neutrophil recovery, reduction in immunosuppressive agents, and a subsequent lobectomy...

Mucormycosis is a rapidly progressive disease with high mortality reported mostly in immunocompromised individuals. We report a case of Rhino-orbital mucormycosis (Lichtheimia corymbifera) in an immunocompetent individual with history of consumption of Aluminium Phosphide (ALP) tablets. We postulated the following effects of ALP poisoning that would have increased the chances of mucormycosis in this patient: 1) Metabolic acidosis; 2) Acute Kidney Injury (AKI); and 3) Liberation of free oxygen radicals.

Mucormycosis is an opportunistic infection caused by the fungi of the Mucorales order of the class Zygomycetes. Gastrointestinal mucormycosis is an uncommon, fatal condition accounting for only 7% of the cases. We present the case of a gastroduodenal mucormycosis presenting as recurrent massive hematemesis. We report this case to alert clinicians of this rare but fatal condition and to encourage further research into its pathogenesis and management.

A 17-year-old female with recently relapsed acute lymphoblastic leukaemia and a treatment course complicated by rhinocerebral mucormycosis infection developed severe peripheral neuropathy during the treatment for mucormycosis infection. This was felt to be a medication side effect. Her peripheral neuropathy was refractory to many well-established treatments, but ultimately responded dramatically and consistently to a novel therapy, topical doxepin cream (5%). This case report is the first published report of the application of topical doxepin cream for treatment of peripheral neuropathy in a paediatric patient...

A 57 year old man was referred from an outside facility for an unresolving pneumonia. Imaging of the chest demonstrated a right lung mass with a consolidation in the middle lobe, pleural effusion, and mediastinal lymphadenopathy. Cytologic examination of cultures from the bronchoscopy and thoracentesis did not yield a definitive diagnosis. Video-assisted thoracoscopic surgery (VATS) was performed because of a retained hemothorax and a suggestive lesion. Biopsy specimens obtained during VATS were consistent with mucormycosis...

Mucormycosis in humans has been described as early as 1885 in literature. Isolated renal mucormycosis is rare as it has been mainly described in developing countries like India and China. It is rarer still to find this entity in immunocompetent young males without any risk factors. Specific guidelines on the treatment is not yet known but combined surgical and medical therapy is considered the best modality for its management. We describe a young male who presented with bilateral hydroureteronephrosis. He was initially treated as a case renal tuberculosis which is relatively more common in TB endemic country like ours...

Pythiosis is caused by Pythium insidiosum, a fungus-like microbe belonging to the kingdom Stramenopila. Its diagnosis is challenging due to clinical and histopathological similarities with the fungal microbes that cause mucormycosis and entomophthoramycosis. In addition, the proper identification of P. insidiosum in the clinical laboratory is difficult. We have developed a rapid and accurate, species-specific identification method using a thermophilic helicase DNA amplification (tHDA) technique, to differentiate this pathogen from closely related pathogenic fungi...

Cutaneous mucormycosis is a rare but often fatal invasive fungal infection that occurs most commonly in patients with diabetes, malignancy, and other immunocompromising conditions. We report an extremely preterm (<28 weeks) baby boy who developed polymicrobial sepsis and primary cutaneous mucormycosis within his first 10 days of life. He was successfully treated with medical management alone since he was not a candidate for surgery. Successful treatment of cutaneous mucormycosis without surgical debridement has been reported on only two other occasions...

Isavuconazole (ISZ) is a newly available broad-spectrum triazole agent recently approved for the treatment of both invasive aspergillosis and mucormycosis. The aim of this study was to develop a simple and reliable method for therapeutic drug monitoring (TDM) of ISZ in human plasma samples. The method involves using a kit from ChromSystems intended for TDM of itraconazole (ITZ), posaconazole (PSZ), and voriconazole (VRZ) in serum/plasma for sample preparation and high-performance liquid chromatography, using fluorescence detection with emission and excitation wavelengths set to 261 and 366 nm, respectively...

A 61 year-old man with a history of hypertension, type2 diabetes, chronic renal failure, tuberculosis and peripheral arterial disease presented with gangrene in the right leg. A right supracondylar amputation was performed, despite which the patient continued with a high fever, oliguria and hypotension (90/50). Laboratory work-up showed neutrophilic leukocytosis and metabolic acidosis. CT revealed pneumoperitoneum, emphysema and thickening of the gastric wall. Changing the CT window we can appreciate air dissecting the layers of the gastric wall...
