Let's analyze the statements:
A is False. "Panting" is a term sometimes used for the heart condition in FMD survivors, but the characteristic sequela is lameness, not panting.
B is True. Hydrophobia, or fear of water, is a classic clinical sign of Rabies in humans, caused by painful spasms of the throat muscles when trying to swallow.
C is True. Penicillin and other beta-lactam antibiotics work by inhibiting the formation of peptidoglycan cross-links in the bacterial cell wall, leading to cell lysis.
D is True. The presence of "zebra markings" (streaks of congestion and hemorrhage) in the rectum and large intestine is a pathognomonic (specifically characteristic) post-mortem finding for Rinderpest.
Therefore, statements B, C, and D are correct.
