Thermoregulatory responses include redirecting blood to or from cutaneous vascular beds only.
Different mechanisms that can produce fever include pyrogens, heat production exceeding heat loss and defective heat loss.

Most Staphylococcus strains possess factors that protect the organism from the host defenses. Which of the ff statements is true?
The so called slime layer is a polysaccharide capsule which facilitates optogenesis.
The clumping factor interacts with fibrinogen to cause large clumps of organisms promoting phagocytosis.
Protein A is present in both Staphylococcus aureus and coagulase (-) staph and reacts specifically with IgG.
Panton-Valentin leucocidin combines with phospholipid layer in the leukocytic cell membrane producing increased permeability and eventual cell death.
This is know as the super antigen that produces interleukin-1 and tumor necrosis factor.

A 1 year and 6 mos old female goes to your clinic for checkup. Patient has been having cough and colds for the past 5 days associated with fever. She was given carbocisteine drops, salinase nasal drops and paracetamol drops.
