Explain the characteristics that makeup Salmonella.

Salmonella is a Gram-negative, facultatively anaerobic bacteria belonging to the Enterobacteriaceae family that is highly adaptive and often leads to severe illnesses in humans and animals alike. Salmonella possesses several vital characteristics contributing to its pathogenicity and ability to cause disease: First is Motility: Salmonella is highly mobile, having peritrichous flagella to facilitate corkscrew-like movement within host tissues and colonizing various organs (CDC, 2021). This allows it to invade host tissues more readily and spread disease. The second characteristic is Biofilm Formation: Salmonella bacteria can form biofilms - communities of bacteria attached by an extracellular matrix produced by itself - which provide protection from environmental stresses and disinfectants and enable Salmonella to remain viable in various environments, including food processing equipment or utensils (Rabsch et al., 2002).

Third, Salmonella exhibits a wide array of antigens, such as O, H, and Vi antigens that help it escape the host immune response and cause infection. This diversity facilitates their survival. Fourth, Salmonella contains various secretion systems, including type III secretion system (T3SS), which allow it to directly inject effector proteins into host cells for invasion and survival in these environments. Fifth, Salmonella bacteria can thrive in various environments, from food, water, soil, and animal and human guts - giving it the edge in terms of survival and spreading throughout different settings (Ohl & Miller, 2001).

Discuss transmission routes between various strains of Salmonella. Include what the different transmission routes are used for.

Transmission Routes of Different Strains of Salmonella: Salmonella can spread via multiple routes that may differ depending on its strain and individual circumstances. Some common transmission pathways include the Fecal-oral way of Salmonella transmission: This is the primary mode of infection with this bacterium, occurring when food, water, or surfaces contaminated with Salmonella become consumed by an individual who may already be infected. Salmonella strains, such as those associated with raw eggs, raw meat, unpasteurized dairy products, fruits, vegetables, or water, become ingestion...
