Summary
Antibiotic treatment in young ostriches led to a rare disease causing anorexia, stunting, and stomach impaction due to Rhizopus oryzae fungal infection.
Area of Science:
- Veterinary Pathology
- Mycology
- Avian Medicine
Background:
- A novel disease affecting young ostriches was observed following antibiotic administration.
- Clinical signs included anorexia, stunting, and stomach impaction.
Purpose of the Study:
- To identify the causative agent of the unusual disease in ostriches.
- To characterize the pathological findings associated with the condition.
Main Methods:
- Gross and histological examination of affected ostrich ventriculi.
- Isolation and identification of fungal pathogens from affected tissues.
Main Results:
- Consistent findings included massive gelatinous mucus accumulation and glandular necrosis in the ventriculus.
- Histological analysis revealed zygomycete invasion of the gastric tissue.
- The fungus Rhizopus oryzae was successfully isolated from all affected birds.
Conclusions:
- Rhizopus oryzae is identified as the causative agent of this specific ostrich disease.
- The disease is characterized by severe gastric pathology and fungal invasion.
- Further research into the link between antibiotic use and this fungal infection is warranted.

01:29Fungal Group Zygomycota
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...
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,...
01:25Inhalation Anthrax
Anthrax is a zoonotic disease caused by Bacillus anthracis, a Gram-positive, spore-forming bacterium. It primarily affects herbivorous animals but can be transmitted to humans through skin contact, ingestion, or inhalation of spores.Cutaneous anthrax, the most common form, typically results from direct contact with bacterial spores through skin abrasions and is generally less severe. Gastrointestinal anthrax results from eating undercooked or contaminated meat. It affects the mouth, throat, or...
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...
01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...
