What is chlamydia in biology?
Chlamydia is a genus of pathogenic Gram-negative bacteria that are obligate intracellular parasites. Chlamydia infections are the most common bacterial sexually transmitted diseases in humans and are the leading cause of infectious blindness worldwide.
What does Chlamydia classify as?
Because of their dependence on host biosynthetic machinery, the chlamydiae were originally thought to be viruses; however, they have a cell wall and contain DNA, RNA, and ribosomes and therefore are now classified as bacteria.
What phylum does Chlamydia trachomatis belong to?
Chlamydiae are a bacterial phylum and class whose members are obligate intracellular pathogens. Many chlamydiae coexist in an asymptomatic state within specific hosts. It is widely believed that these hosts provide a natural reservoir for these species. All known chlamydiae only grow by infecting eukaryotic host cells.
What are the characteristics of C. trachomatis?
C. trachomatis is an obligate, aerobic, intracellular parasite of eukaryotic cells. It is a Gram-negative bacteria and has a coccoid or rod shape. It has a cytoplasmic membrane and outer membrane similar to Gram-negative bacteria (thus, it being classified as Gram-negative) but, it lacks a peptidoglycan cell wall.
Is chlamydia bacterial or viral?
Bacterial infections include chlamydia, gonorrhea, and syphilis. Viral infections include human papillomavirus (HPV), herpes (HSV or herpes simplex virus), human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and Hepatitis B.
Is chlamydia a parasite or bacteria?
Chlamydia is a common sexually transmitted disease. It is caused by bacteria called Chlamydia trachomatis.
Is chlamydia eukaryotic or prokaryotic?
It is now known that the chlamydiae are actually prokaryotic organisms, and what was originally thought to be the hooded cloak is in fact a cytoplasmic vesicle containing numerous individual organisms and is termed an inclusion (1).
Is it Chlamydia or chlamydiae?
Chlamydiae are obligate intracellular parasites that cause a variety of diseases in animal species at virtually all phylogenic levels. Traditionally, the order Chlamydiales has contained one genus with four recognized species: Chlamydia trachomatis, Chlamydia psittaci, Chlamydia pneumoniae, and Chlamydia pecorum.
Is Chlamydia bacterial or viral?
What are the characteristics of chlamydiae?
Chlamydiae are obligate, intracellular, nonmotile, gram-negative bacteria with a unique biphasic developmental cycle consisting of extra- and intracellular forms. Chlamydiae have an outer membrane that contains lipopolysaccharide (LPS) and membrane proteins. Peptidoglycan is present in the septum of dividing bacteria.
What kind of smell does chlamydia have?
Does chlamydia have a smell? Chlamydia doesn’t always have a smell. But one of the symptoms of chlamydia is an unusual vaginal discharge that has an unpleasant odor.
What is the meaning of the name Chlamydiae?
chlamydiae: Chlamydiae is a bacterial phylum and class whose members are obligate intracellular pathogens. inclusion body: Inclusion bodies are nuclear or cytoplasmic aggregates of stainable substances, usually proteins.
What is the pathophysiology of chlamydia?
Chlamydiae are a bacterial phylum and class whose members are obligate intracellular pathogens. Many chlamydiae coexist in an asymptomatic state within specific hosts. It is widely believed that these hosts provide a natural reservoir for these species. All known chlamydiae only grow by infecting eukaryotic host cells.
Is Chlamydia an intracellular or multicellular parasite?
Chlamydia – Medical Microbiology – NCBI Bookshelf The chlamydiae are a small group of nonmotile coccoid bacteria that are obligate intracellular parasites of eukaryotic cells.
What is the life cycle of chlamydia?
Chlamydia. Chlamydia are obligatory intracellular spheric or ovoid bacteria with a complex intracellular life cycle; the infective form is the elementary body, which penetrates the host cell, replicating as the rediculate body by binary fission; replication occurs in a vacuole called the inclusion body; lack peptidoglycan in cell walls;
