What populations are at higher risk for pseudomonas infections and why?
Press to flip
Populations at higher risk for pseudomonas infections include individuals with acute COPD exacerbations, recent surgery or trauma, living in close quarters, due to their opportunistic nature and preference for moist environments.
Discuss the complications that can arise from streptococcal pneumonia in immunocompromised individuals.
Complications from streptococcal pneumonia in immunocompromised individuals can include sepsis, empyema, bacteremia, and meningitis.
What are the preferred treatment methods for C. diff infections and why?
Preferred treatments for C. diff infections include probiotics and specific antibiotics to restore normal gut flora and target the bacteria effectively.
How long can C. diff spores survive on surfaces and what cleaning method is effective against them?
C. diff spores can survive up to months on surfaces and require bleach or commercial disinfectant wipes that air-dry for 2 minutes to be effectively cleaned.
List the common symptoms and transmission route for pseudomonas infections.
Pseudomonas infections can include respiratory issues, bacteremia, CNS involvement, soft tissue infections, and osteomyelitis, and are transmitted via moist surfaces or improper hygiene.
How does Staphylococcus aureus commonly enter the body and what are the initial symptoms?
Staphylococcus aureus often enters the body through secretions or traumatic inoculation, leading to symptoms like local abscess, fever, chills, pain, and swelling.
Explain the role and importance of aggressive debridement in the treatment of streptococcal necrotizing fasciitis.
Aggressive debridement is crucial in treating streptococcal necrotizing fasciitis to remove necrotic tissue and reduce bacterial load, improving the effectiveness of antibiotic therapy.
What infection control measures are recommended for preventing Staphylococcus aureus transmissions in healthcare settings?
Recommended infection control measures include strict contact precautions and rigorous hand hygiene practices.
What are the common risk groups for developing a C. diff infection?
Common risk groups include antibiotic users, individuals over 65, and those living with an infected person.
What strain of Staphylococcus is known for its resistance to methicillin and what is the primary antibiotic used for its treatment?
MRSA (Methicillin-resistant Staphylococcus aureus) is treated primarily with vancomycin.
Describe the transmission and primary symptoms of Group A Streptococcal pharyngitis.
Group A Streptococcal pharyngitis is transmitted via respiratory droplets and presents with fever, sore throat, swollen tonsils, and abdominal pain.
What are the characteristic features of scarlet fever and its relationship to Group A Streptococcus?
Scarlet fever is characterized by a fever, sore throat, strawberry tongue, and rash, and is caused by Group A Streptococcus.
What is necrotizing fasciitis and which bacterial group primarily causes it?
Necrotizing fasciitis is a rapidly spreading infection causing severe skin necrosis, primarily caused by Group A Streptococcus.
Identify the symptoms and common transmission route for impetigo caused by Group A Streptococcus.
Impetigo presents with small vesicles, often localized in toddlers, and is transmitted through poor hygiene and minor skin trauma.
What type of bacteria is Clostridioides difficile and where is it typically contracted?
Clostridioides difficile is an anaerobic bacteria typically contracted in hospitals as a nosocomial infection.
