<![CDATA[Streptococcus suis (S. suis) is a significant zoonotic pathogen that can cause severe infections in humans, primarily manifesting as meningitis, septicemia, and endocarditis. This review focuses on the pathophysiology of S. suis meningitis, emphasizing the bacterium's mechanisms for crossing the blood-brain barrier (BBB) and eliciting a robust inflammatory response. The review highlights the virulence factors, including collagenase-like protease and capsular polysaccharides, that facilitate the pathogen's evasion of the immune system and contribute to the severity of the disease. Notably, the prevalence of S. suis infections remains a critical public health concern, particularly in regions with high pig consumption, where occupational exposure increases the risk of human disease. The manuscript also evaluates current diagnostic techniques, comparing traditional methods, such as cerebrospinal fluid culture, with advanced molecular diagnostics, including polymerase chain reaction (PCR) and next-generation sequencing (NGS). These newer methods demonstrate enhanced sensitivity and specificity, crucial for timely and accurate diagnosis. Furthermore, emerging innovations in diagnostic technology, including point-of-care testing and biosensors, hold promise for rapid identification of S. suis, potentially mitigating morbidity associated with the disease. This comprehensive review highlights the urgent need for enhanced diagnostic capabilities and public health strategies to reduce the burden of S. suis meningitis, promoting interdisciplinary collaboration to improve disease prevention and management.]]>
