General MicrobiologyOrthomyxoviruses, which include the influenza viruses, are characterized by their single-stranded RNA genome. This feature distinguishes them from other virus families that may have different types of genetic material. Orthomyxoviruses are distinguished by their single linear RNA genome, which is essential for their replication and pathogenicity.

Physiology
The afferent arterioles are part of the juxtaglomerular apparatus along with the macula densa and efferent arterioles. When the macula densa detects a decrease in sodium chloride delivery, it triggers the juxtaglomerular cells in the afferent arterioles to release renin, which is the initial step in the RAAS.

Antiphospholipid syndrome is an autoimmune disorder characterized by the presence of antiphospholipid antibodies. These antibodies can bind to phospholipids in cell membranes, leading to a prothrombotic state and an increased risk of thrombosis. The exact mechanism by which these antibodies induce thrombosis is complex and may involve interference with anticoagulant proteins like protein C and protein S, as well as platelet activation and endothelial damage. However, the primary mechanism is the presence of these autoantibodies.

The sudden onset of symptoms, along with neck stiffness and photophobia, suggests meningitis. The CSF findings of a high white blood cell count with a predominance of neutrophils and low glucose are more indicative of bacterial meningitis, as this pattern is less common in viral or fungal meningitis.
