Second-generation cephalosporins are a class of antibiotics that provide a broader spectrum of activity against Gram-positive and Gram-negative bacteria compared to first-generation cephalosporins. They are commonly used to treat infections such as respiratory tract infections, skin infections, and urinary tract infections, offering moderate resistance to beta-lactamases produced by some bacteria.

Second-generation Cephalosporins

Class of antibiotics

Broader spectrum of activity

Gram-positive bacteria are characterized by a thick peptidoglycan layer in their cell wall, which retains the crystal violet stain used in the Gram staining procedure, making them appear purple under a microscope. They are a diverse group of bacteria that include many significant pathogens and are generally more susceptible to antibiotics that target cell wall synthesis.

Gram-positive Bacteria

Gram-negative bacteria are characterized by their unique cell wall structure, which includes a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides. This structure contributes to their resistance to certain antibiotics and their ability to cause severe infections in humans.

Gram-negative Bacteria

First-generation cephalosporins are a class of antibiotics primarily effective against Gram-positive bacteria, commonly used to treat skin and soft tissue infections. They have a narrower spectrum compared to later generations but are preferred for their effectiveness against susceptible staphylococci and streptococci.

First-generation Cephalosporins

Treat infections

Respiratory tract infections encompass a range of illnesses caused by viral or bacterial pathogens affecting the upper or lower respiratory system, with symptoms varying from mild to severe. Effective management relies on accurate diagnosis, appropriate antimicrobial use, and preventive measures like vaccination and hygiene practices.

Respiratory Tract Infections

Skin infections occur when pathogens such as bacteria, viruses, fungi, or parasites invade the skin, leading to inflammation and other symptoms. Effective treatment depends on identifying the type of pathogen involved and may include topical or oral medications, hygiene measures, and sometimes surgical intervention.

Skin Infections

Urinary Tract Infections (UTIs) are common infections that occur when bacteria enter the urinary tract, leading to symptoms such as frequent urination, pain, and urgency. Prompt diagnosis and treatment are crucial to prevent complications like kidney infections and to alleviate discomfort.

Urinary Tract Infections

Moderate resistance

Beta-lactamases

Infections occur when harmful microorganisms, such as bacteria, viruses, fungi, or parasites, invade the body, multiply, and cause disease or damage. The body's immune response is crucial in fighting infections, but the effectiveness of this response can vary based on the pathogen and the individual's health status.
