Bacterial Phylum Actinobacteria01:30

Bacterial Phylum Actinobacteria

561
Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

Actin Polymerization and Cell Motility01:13

Actin Polymerization and Cell Motility

6.4K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate....

Skin Diseases and Disorders

5.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Actin Treadmilling01:18

Actin Treadmilling

9.4K
Actin filaments undergo polymerization and depolymerization from either end. The polymerization and depolymerization rates depend on the cytosolic concentration of free G-actins. The polymerization rate is generally higher at the plus or barbed end, while the depolymerization rate is higher at the minus or pointed end. At a steady state, critical concentration describes the concentration of free G-actin monomers at which the polymerization rate at the plus end is equal to that of the...

Introduction to Actin01:26

Introduction to Actin

6.2K
Actin is a highly conserved cytoskeletal protein found abundantly in eukaryotic cells. It constitutes 10% weight of the total cellular protein in muscle cells, while in non-muscle cells, it is lower and makes up around 1–5 percent of the total cell protein. Actin found in the unicellular amoebae and complex multicellular animals is around 80% similar, demonstrating their conservation over a billion years of evolution.  Actin coding genes are conserved within species and across...

Fungal Phylum Ascomycota01:28

Fungal Phylum Ascomycota

947
Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Summary
This summary is machine-generated.

Actinomycosis is a chronic bacterial infection caused by Actinomyces. Diagnosis involves prolonged anaerobic culture, and treatment typically requires 6-12 months of penicillin G and amoxicillin therapy.

Area of Science:

  • Medical Microbiology
  • Infectious Diseases

Background:

  • Actinomycosis is a chronic bacterial infection caused by the genus Actinomyces, which are commensals of the digestive and genital tracts.
  • While commonly affecting the cervicofacial region, Actinomycosis can also involve abdominal, thoracic, and central nervous system sites.
  • Neoplasia is a key differential diagnosis for suspected Actinomycosis.

Purpose of the Study:

  • To summarize the key aspects of Actinomycosis, including its etiology, clinical presentation, diagnostic methods, and treatment options.

Main Methods:

  • Diagnosis relies on prolonged culture of deep samples in an anaerobic environment, considered the gold standard.
  • Treatment involves intravenous penicillin G followed by oral amoxicillin.

Main Results:

  • The gold standard for Actinomycosis diagnosis is prolonged anaerobic culture of deep samples.
  • The primary treatment regimen consists of intravenous penicillin G followed by oral amoxicillin.

Conclusions:

  • Actinomycosis requires prolonged antibiotic therapy, typically 6 to 12 months.
  • Shorter treatment durations may be considered based on the infection's location and patient response to antibiotics.
