Summary
A fungal infection caused by Candida albicans affected male broiler breeders, specifically their combs and facial skin. This study details the clinical signs and microscopic findings of this cutaneous mycosis in poultry.
Area of Science:
- Veterinary Mycology
- Avian Pathology
Background:
- Candida albicans is a common yeast that can cause opportunistic infections.
- Broiler breeders are crucial for poultry production, making flock health a priority.
Observation:
- A cutaneous mycosis was observed in male broiler breeders, primarily affecting the combs and wattles.
- Lesions included white, adherent, crusty patches and diffuse areas, sometimes with black scabs.
- Affected areas showed hyperkeratosis with minimal inflammation and the presence of yeast and pseudohyphae.
Findings:
- High numbers of Candida albicans were isolated and identified from the affected tissues.
- Morbidity varied between flocks (10% vs. <2%), but mortality and fertility were unaffected.
- Microscopic examination confirmed hyperkeratosis and intralesional fungi consistent with Candida albicans.
Implications:
- This study highlights Candida albicans as a potential pathogen causing cutaneous mycosis in broiler breeders.
- Understanding the clinical presentation and causative agent is crucial for effective diagnosis and management in poultry farms.
- Further research may be needed to explore preventative measures and treatment options for this condition.

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...
01:18Trichomoniasis
Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
