Following a rattlesnake bite, a patient is injected with horse anti-rattlesnake venom, serum. Ten days later he has general weakness, muscular and joint pains. Laboratory studies show Proteinuria. Serum concentrations of immunoglobulins are within the reference range, but serum c3 and c4 qare decreased. Which is the most likely pathologic proces (A) Anaphylactic reaction (B) Delayed hypersensititvity to horse proteins (C) Formation of antigen-antibody complexes containing horse proteins and human immunoglobulins

43. A patient who has been bitten by a rattlesnake is given an injection of equine anti-rattlesnake venom. Ten days later, he still feels weak all over, has headaches, aches in his muscles and joints, and has black urine. Studies in the lab reveal proteinuria. Immunoglobulin levels in the serum are within the normal range, while serum C3 and C4 levels are lower. Which of the following pathological processes is more likely? (A) Anaphylactic Reaction (B) Delayed Hypersensitivity to horse protein (C) Formation of antigen-antibody complexes containing horse proteins and human immunoglobulin (D) Formsation of antigen-antibody complexes containing snake venom proteins and a horse antibody (E) Systemic reaction to snake venom

(>1 ans) Which of the following statements is/are correct? Hepatitis A viral infection will result in long-lasting immunity against subsequent infection. For disinfection of enteroviruses, such as hand-foot-mouth disease viruses, acidic disinfectant is effective. Prior rotaviral infection may not prevent subsequent infection of the same virus. For poliovirus and enterovirus-71, both neutralizing antibodies and cellular immunity are critical for defending the host against the pathogens. There is an effective vaccine available for noroviral infection due to its availability of animal models.
