Nose and Nasal Cavity01:24

Nose and Nasal Cavity

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...
Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

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 like...
Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
Botulism01:22

Botulism

Botulism is a life-threatening neuroparalytic condition caused by botulinum neurotoxin, which is produced by the bacterium Clostridium botulinum, a Gram-positive, spore-forming, obligate anaerobe.In adults, the toxin enters the body in different ways: in foodborne botulism, the preformed toxin is absorbed in the intestine. In wound botulism, spores grow in injured tissue and release the toxin into the blood. Infant botulism differs mechanistically from adult forms. In infants, botulism commonly...

Area of Science:

  • Veterinary Parasitology
  • Entomology
  • Zoology

Background:

  • Obligatory myiasis-causing larvae, particularly nasal bots (Oestridae), affect various animals and humans, impacting nasopharyngeal cavities, wounds, and internal organs.
  • Nasal bots are prevalent in Mediterranean and tropical regions, causing significant discomfort and respiratory distress in hosts through sneezing and nasal discharge.

Purpose of the Study:

  • To explore the fascinating morphological, biological, and life cycle adaptations of nasal bot larvae and adults.
  • To investigate host behavioral and immune responses to nasal bot infections, including pathophysiological mechanisms and their impact.

Main Methods:

  • Review of existing literature on Oestridae family, focusing on genera like Oestrus, Rhinoestrus, and Gedoelstia.
  • Analysis of larval adaptations, life cycle complexities (direct larval injection vs. migration), and hypobiosis.
  • Examination of host-parasite interactions, including behavioral avoidance, immune responses (mast cells, eosinophils), and clinical manifestations in different hosts.

Main Results:

  • Nasal bots display remarkable adaptations for parasitism, with diverse life cycles including direct larval development and complex migration routes.
  • Host immune responses, particularly eosinophilia, play a crucial role in limiting larval development, sometimes with systemic effects.
  • Clinical signs vary significantly between hosts; bacterial infections are often overestimated, and effective treatments include macrocyclic lactones, closantel, and nitroxynil.

Conclusions:

  • Nasal bots are highly adapted parasites with complex life cycles and significant host-parasite interactions.
  • Understanding host responses is crucial for managing myiasis, with specific treatments available for effective control.
  • Despite their impact, nasal bot infections are manageable with appropriate veterinary interventions, though reinfections are common.
