The article discusses three pathogens that can cause meningitis: Haemophilus influenzae type b, Neisseria meningitidis, and Streptococcus suis. It then describes a case study of a man who contracted S. suis meningitis after slaughtering pigs without protective gear. An MRI and spinal tap were performed, and S. suis was identified as the cause. The man's exposure to the pigs through slaughtering them without protection was likely how he contracted the infection.
