there are three pathways for pathogens to to enter the ear, what are they?
1.auditory tube also known as esutachian tube present in the throat and nose
2.pathogens can easily enter through external ear.
3.other way of entering in the pathogens to ear is blood and lymph
This pathogens can cause various infections such as ottitis media,ottorrhoea,labyrinhittis.most of the ear i fections occurs in middle ear
there are three pathways for pathogens to to enter the ear, what are they?
Many pathogens enter the human body via the upper respiratory system. Please identify both the viral and bacterial pathogens that infect the upper respiratory system. Specifically, the sinuses, the auditory tube, the nasal cavity, middle ear, and the trachea.
Based on your knowledge of complement activation pathways, predict which group of pathogens would be MOST susceptible to lysis by MACs. Gram-negative pathogens Enveloped viruses Gram-positive pathogens Gram-negative pathogens and enveloped viruses are equally susceptible. Gram-negative pathogens and enveloped viruses are equally susceptible. Every possible light chain that could be formed, in terms of receptor specificity, is encoded by a separate gene within the human genome. Light chains are produced by means of somatic rearrangement of germ-line DNA in B...
What are three ways that commensal bacteria use to protect themselves and their host from pathogens?
As sound waves enter the ear, in what order do they reach the structures of the outer, middle and inner ear? A. pinna, auditory canal, tympanic membrane, ossicles, cochlea B. pinna, cochlea, auditory canal, tympanic membrane, ossicles C. auditory canal, ossicles, tympanic membrane, cochlea, pinna D. cochlea, ossicles, tympanic membrane, pinna, auditory canal
Diagram the three pathways of complement.
What are the common pathogens for acute sinusitis? List the top three antimicrobials indicated in the literature or in guidelines for non-allergic (bacterial) sinusitis. Discuss the pharmacokinetics/dynamics, side effects, and contraindications of each. What are the costs of each of these three antimicrobials? B What is the most common organism for pharyngitis? How is it diagnosed? Locate the most up-to-date clinical practice guideline for management of pharyngitis and discuss its recommendations. Provide a link to the reference and use APA...
