Infection

Medical Definition: Invasion and multiplication of microorganisms in body tissues, which may be clinically inapparent or result in local cellular injury. A local infection may persist and spread by extension to become an acute, subacute, or chronic clinical infection or disease state. It may also become systemic when the microorganisms gain access to the lymphatic or vascular system. (From Dorland, 27th ed)
Guide Notes: GEN only as concept of dis caused by organisms; many texts saying "infection" & many saying "sepsis" mean BACTERIAL INFECTIONS: check text but note that SEPSIS is available; "infectious disease" can be INFECTION but is more likely COMMUNICABLE DISEASES; p
Also Called: Infections, Reproductive Tract
Infection Categories.
Canadian Medical Guide Definition Aneurysm, Infected - Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms.
Canadian Medical Guide Definition Arthritis, Infectious - Arthritis caused by bacteria, rickettsiae, mycoplasmas, viruses, fungi, or parasites. Bacterial arthritis is frequently caused by Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria gonorrhoeae. Viral arthritis is less common than bacterial arthritis and may be a manifestation of such viral diseases as mumps, rubella, hepatitis, etc.
Canadian Medical Guide Definition Bone Diseases, Infectious - Bone diseases caused by pathogenic microorganisms.
Canadian Medical Guide Definition Communicable Diseases
Canadian Medical Guide Definition Community-Acquired Infections - Any infection acquired in the community, that is, contrasted with those acquired in a health care facility (CROSS INFECTION). An infection would be classified as community-acquired if the patient had not recently been in a health care facility or been in contact with someone who had been recently in a health care facility.
Canadian Medical Guide Definition Cross Infection - Any infection which a patient contracts in a health-care institution.
Canadian Medical Guide Definition Eye Infections - Infection, moderate to severe, caused by bacteria, fungi, or viruses, which occurs either on the external surface of the eye or intraocularly with probable inflammation, visual impairment, or blindness.
Canadian Medical Guide Definition Focal Infection
Canadian Medical Guide Definition Laboratory Infection - Accidentally acquired infection in laboratory workers.
Canadian Medical Guide Definition Ludwig's Angina - Severe cellulitis of the submaxillary space with secondary involvement of the sublingual and submental space. It usually results from infection in the lower molar area or from a penetrating injury to the mouth floor. (From Dorland, 27th ed)
Canadian Medical Guide Definition Opportunistic Infections - An infection caused by an organism which becomes pathogenic under certain conditions, e.g., during immunosuppression.
Canadian Medical Guide Definition Pelvic Infection - Infection involving the tissues or organs in the PELVIS.
Canadian Medical Guide Definition Pregnancy Complications, Infectious - Infections occurring during the course of pregnancy, or pregnancy during the course of an infectious disease.
Canadian Medical Guide Definition Prosthesis-Related Infections - Infections resulting from the implantation of prosthetic devices. The infections may be acquired from intraoperative contamination (early) or hematogenously acquired from other sites (late).
Canadian Medical Guide Definition Reiter Disease - A triad of nongonococcal urethritis followed by conjunctivitis and arthritis, of unknown etiology.
Canadian Medical Guide Definition Respiratory Tract Infections
Canadian Medical Guide Definition Sepsis - The presence of pathogenic microorganisms or their toxins in tissues or in the blood. Systemic disease caused by the spread of the microorganisms via the circulating blood is commonly called SEPTICEMIA. (From Stedman, 25th ed)
Canadian Medical Guide Definition Sexually Transmitted Diseases - Diseases due to or propagated by sexual contact.
Canadian Medical Guide Definition Skin Diseases, Infectious - Skin diseases caused by bacteria, fungi, parasites, or viruses.
Canadian Medical Guide Definition Soft Tissue Infections - Infections of non-skeletal tissue, i.e., exclusive of bone, ligaments, cartilage, and fibrous tissue. The concept is usually referred to as skin and soft tissue infections and usually subcutaneous and muscle tissue are involved. The predisposing factors in anaerobic infections are trauma, ischemia, and surgery. The organisms often derive from the fecal or oral flora, particularly in wounds associated with intestinal surgery, decubitus ulcer, and human bites. (From Cecil Textbook of Medicine, 19th ed, p1688)
Canadian Medical Guide Definition Suppuration - A pathologic process consisting in the formation of pus.
Canadian Medical Guide Definition Toxemia - A generalized intoxication produced by toxins and other substances elaborated by an infectious agent.
Canadian Medical Guide Definition Urinary Tract Infections - Infections affecting those structures of the body which participate in the secretion and elimination of urine, i.e., the kidney, the ureters, the urinary bladder, and the urethra.
