|November 21, 2009
Summary
A plant pathogen, Corynespora cassiicola, caused a rare subcutaneous infection in a diabetic farmer. Prompt identification and amphotericin B treatment led to successful recovery.
Area of Science:
- Mycology
- Infectious Diseases
- Plant Pathology
Background:
- Diabetes mellitus is a common comorbidity that can increase susceptibility to infections.
- Subcutaneous infections can arise from various microbial agents, including plant pathogens.
- Corynespora cassiicola is primarily known as a plant pathogen, with limited reports of human infections.
Observation:
- A 69-year-old female farmer presented with a subcutaneous infection.
- The infection was caused by the plant pathogen Corynespora cassiicola.
- The patient had a history of diabetes mellitus.
Findings:
- Morphological characteristics of the causative agent were consistent with Corynespora cassiicola.
- Sequence analysis of the internal transcribed spacer (ITS) regions confirmed the identification of Corynespora cassiicola.
- The patient's diabetes mellitus was a potential predisposing factor.
Implications:
- This case highlights the potential of Corynespora cassiicola to cause subcutaneous infections in humans, particularly in immunocompromised individuals.
- Accurate identification of the pathogen through morphological and molecular methods is crucial for effective treatment.
- Amphotericin B demonstrated efficacy in treating this rare subcutaneous fungal infection.

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
