Fungal rhinitis in dogs
Polish Journal of Veterinary Sciences
|January 27, 2016
Summary
Fungal rhinitis in dogs is often diagnosed via rhinoscopy. Histopathology is the gold standard for diagnosis, while nasal swab cytopathology has limited diagnostic value for canine fungal infections.
Area of Science:
- Veterinary Medicine
- Mycology
- Canine Diseases
Background:
- Fungal rhinitis and sinusitis are common causes of chronic nasal discharge in dogs.
- Rhinoscopy is frequently recommended for diagnosing these conditions.
Purpose of the Study:
- To evaluate the diagnostic value of different methods for canine fungal rhinitis.
- To compare histopathology and cytopathology in diagnosing fungal nasal infections in dogs.
Main Methods:
- Forty-three dogs with chronic respiratory symptoms underwent rhinoscopy.
- Diagnostic procedures included clinical examination, hematology, biochemistry, radiography, CT (one dog), histopathology, and cytopathology (nasal swabs).
Main Results:
- Fungal rhinitis was diagnosed in 9 out of 43 dogs (20.5%), all male, aged 1-13 years.
- Histopathology confirmed mycosis in 7 cases, while cytopathology alone diagnosed it in 2 cases.
- Cytopathological examination of nasal swabs showed low diagnostic value.
Conclusions:
- Histopathology of samples collected during rhinoscopy remains the gold standard for diagnosing fungal rhinitis in dogs.
- While cytopathology can be supplementary, it is insufficient as a sole diagnostic tool for canine nasal fungal infections.

01:16Drugs Used in Upper Respiratory Disorders: Overview
988
Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...

01:29Fungal Group Zygomycota
2.1K
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...

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
2.0K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

01:29Microbiota of the Respiratory Tract
16
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

01:24Nose and Nasal Cavity
15.3K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

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...
