• Each part is illustrated with a descriptive animation.
• A comparative description of the cell wall in both gram-positive and gram-negative bacteria is provided in this section.
• A variety of bacteria will be widely discussed in this bacteriology PPT template.

Streptococcus pyogenes

Streptococcus pyogenes characteristics

• S. pyogenes is characteristically a gram-positive bacterium, a round-to-ovoid coccus with a thick peptidoglycan layer, non-motile, non-spore-forming and facultatively anaerobic.
• They divide in one plane and thus occur in pairs or (especially in liquid media or clinical material) in chains of varying lengths.

Virulence factors

• Animated illustrations in Bacteria PPT explain the role and mechanisms of capsules and toxins as virulence factors.
• S. pyogenes can produce several pathogenic virulence factors, including bacteriocins, hemolysin O, streptokinase, NADH enzyme, hyaluronidase and M protein.

Infection

• Pneumonia, lung abscess, brain abscess, meningitis and infective endocarditis
• A common complaint in cases of streptococcus pharyngitis is a sore throat. Clinical manifestations of streptococcal pharyngitis most frequently include fever that strikes suddenly, malaise, pharyngeal discharge, sensitive cervical lymphadenopathy and swollen tonsils.
• One of the most typical skin illnesses is impetigo. S. pyogenes causes non-bullous impetigo.
• A high-grade fever, sore throat, strawberry-like tongue and a blanchable, papular, non-confluent rash are the typical symptoms that a patient with scarlet fever presents with.
• Group A streptococcus (S. pyogenes) causes necrotizing fasciitis, a deep-seated subcutaneous tissue infection that quickly destroys fat and fascia.
• Post-infection sequela, diagnosis and treatment are illustrated with medical icons.

Streptococcus pneumoniae

Streptococcus pneumoniae characteristics

• Streptococcus pneumoniae is a lancet-shaped, gram-positive, facultative anaerobic bacteria with more than one hundred known serotypes.
• Non-motile, non-spore-forming, with a thick peptidoglycan layer.

Virulence factor

• Animation illustrations explain that the organism produces a range of colonization and virulence factors, including the polysaccharide capsule, surface proteins and enzymes, biofilm, IgA protease, pili and the toxin pneumolysin (PLY).
• The description and mechanism of these virulence factors are illustrated with animations.

Infection

• Medical illustrations in the Bacteria PPT show that the organism colonizes the nasopharynx and can cause otitis media, pneumonia, bacteremia, pneumococcal endocarditis and meningitis.

Diagnosis

• Removing the organism from blood or other typically sterile body areas is necessary for a definitive diagnosis of Streptococcus pneumoniae infection.
• Diagnostic methods include PCR and cultures.
• Additionally, tests are available to show the capsular polysaccharide antigen in bodily fluids.

Vaccine

• There are two kinds of pneumococcal vaccines recommended in the United States:

1. Pneumococcal conjugate vaccines (PCVs, specifically PCV15 and PCV20).
2. Pneumococcal polysaccharide vaccine (PPSV23).

Treatment

• Medical infographics explain that High-risk Groups like older people, children under two years and people with chronic diseases should be vaccinated.

Enterococcus

Enterococcus characteristics

• Enterococci are Gram-positive facultative anaerobic cocci in short and medium chains.
• It can tolerate extreme conditions like high-temperature high sodium chloride concentration and high PH conditions.

Virulence factors

• The potential virulence factors of enterococci include the production of enterococcal surface protein (Esp), gelatinase and hemolysin.
• Other virulence factors are explained in Bacteria PPT with animated illustrations explaining the mechanisms of biofilm formation and antibiotic resistance (acquired and inherited).

Hospital-Acquired Infection

• Hospital patients are often found to have Enterococcus spp—infections, which are linked to a high death rate.
• Enterococci are essential nosocomial pathogens causing up to 10% of all infections in hospitalized patients.
• The infections include urinary tract infection, biliary tract infection and subacute endocarditis.

Diagnostic methods

• These methods include imaging and lab tests.

Clostridium

Clostridium tetani

Clostridium characteristics

• C. tetani is part of a genus of obligate anaerobic, saprophytic, gram-positive organisms and toxin-producing.

Habitat

• It is an organism that forms spores, is resistant to extreme temperatures and can live indoors and outdoors.
• Present in soil, sewage and intestine.
• It is impossible to remove from the environment.
• Tetanus spores are widely known to be heat- and disinfectant-resistant microorganisms that can persist in the background for several years.

Clostridium tetani Transmission

• For most people, an open wound is the cause of infection. Others may experience tetanus because of gangrene, burn injuries, surgical site abscesses, or intravenous drug misuse.

Pathogenesis

• Toxin-producing organism and considered the most dangerous of its genus clinical manifestations.
• Severe, diffuse muscle contractions characterize tetanus. The muscular rigidity and spasms of tetanus are caused by tetanus toxin (tetanospasmin).
• Treatment

Clinical manifestations

• Characterized by trismus lockjaw and opisthotonos position tetanus.

Prevention

• Use toxoid vaccine to initiate the immunity and booster dose needed.

Clostridium botulinum

Characteristics

• Clostridium botulinum is an anaerobic spore-forming gram-positive bacillus.
• It produces the most potent biological toxin known, botulinum neurotoxin.

Transmission

• Home-preserved (pickled and canned) foods, especially vegetables, seafood and cured meats, are the main foods linked to the spread of botulism.
• Infant botulism cases have been linked to honey.

Pathogenesis

• As illustrated in Bacteria PPT, BT binds to the acetylcholine receptors on the neuromuscular junctions, resulting in blockage of the release of the neurotransmitter, leading to flaccid paralysis.

Clinical manifestation

• The weakening of the muscles controlling the eyes, face, mouth and throat is typically the first sign of botulism. The neck, arms, chest and legs could all become weaker.
• Floppy paralysis is a characteristic sign.
• Additionally, botulism has the potential to impair the breathing muscles, which can result in breathing difficulties or even death.
• A comparative illustration between C. tetani and C. botulinum is provided to differentiate between the two mechanisms, involved neurotransmitters, symptoms and the type of paralysis.

Clostridium perfringens

Characteristics

• Clostridium perfringens is a Gram-positive, bacillus (rod-shaped), anaerobic, spore-forming pathogenic bacterium of the genus Clostridium.

Virulence factors

• Alpha toxin (CPA), Beta toxin (CPB), Theta toxin, C. perfringens enterotoxin (CPE), Epsilon toxin (ETX), Iota toxin (ITX), Necrotic enteritis B-like toxin (Net B).

Pathogenesis

• Animated illustration in the Bacteria PPT template explains that the organism penetrates the wounds and secretes alpha and theta toxins, leading to extensive tissue damage and foul-smelling gas gangrene.

Treatment

• Gas gangrene mostly ends with surgical debridement and intensive antibiotic use.
• Food poisoning is a self-healing case and needs hydration.

Clostridium difficile

• It is usually present in normal flora; normal flora limits it, but the antibiotics wipe out the normal flora, leading to the permission of C. difficile overgrowth.

Pathogenesis

• Toxin A (enterotoxin) causes intestinal inflammation and increased fluid secretion.
• Toxin B (cytotoxic) induces cell apoptosis.
• These toxins' pathogenic action leads to ulcerative colitis and diarrhea.

Diagnosis

• Diagnosed by PCR and stool samples.

Treatment options

• Bacterial diseases are treated with antibiotics, considering the resistance to some types, sensitivity to some antibiotics and the type of the causative organism, as mentioned in the Bacteria PPT template.
