Final answer:
The most likely nonzoonotic entity to cause pinkeye or conjunctivitis in technicians is Staphylococcus aureus. This type of bacterial conjunctivitis is common in clinical settings and can be diagnosed through various laboratory tests.
Therefore, option B is correct.
Step-by-step explanation:
The nonzoonotic entity most likely to cause pinkeye or conjunctivitis in technicians is Staphylococcus aureus (b). Bacterial conjunctivitis can be caused by different species of bacteria, including Haemophilus influenzae, S. pneumoniae, and S. aureus. While Candida is a fungus and Chlamydia trachomatis can cause chlamydial conjunctivitis and trachoma, S. aureus is a common cause of conjunctivitis particularly in a hospital or clinical setting where technicians might be exposed. Accurate identification of the causative agent can be done through bacterial cultures and various tests such as Gram stain, antigenic, or nucleic acid profile tests of the isolated pathogen. Contact lens wearers and healthcare workers are advised to observe proper hygiene and handle contact lenses with care to reduce the risk of infection.
