STREPTOCOCCUS Flashcards
STREOPTOCOCCUS CAUSES WHAT THREE MAIN THINGS?
- SEPTICEMIA
- STRANGLES
- MASTITIS
STREPTOCOCCUS CAUSES THREE TYPES OF HEMOLYSIS. WHAT ARE THEY?
BETA HEMOLYTIC- COMPLETE HEMOLYSIS
ALPHA HEMOLYTIC- PARTIAL HEMOLYSIS
GAMMA HEMOLYTIC- NO HEMOLYSIS
STREPTOCOCCUS GENERAL FACTS
GRAM POSITIVE COCCI CHAINS CATALASE NEGATIVE FACULTATIVE ANAEROBE COMMENSAL IN MUCOUS MEMBRANES ZOONOTIC PRIMARY OPPORTUNISTIC PATHOGEN LOW ENVT RESISTANCE
STREPTOCOCCUS VIRULENCE FACTORS THAT FUNCTION IN INVASION
STREPTOKINASE
HYALURONIDASE
STREPTOCOCCUS VIRULENCE FACTOR THAT FUNCTIONS IN ADHESION
PROTEIN F
STREPTOCOCCUS VIRULENCE FACTORS THAT FUNCTION IN EVASION
M PROTEIN
HYALURONAN
HEMOLYSIN/STREPTOLYSIN
STREPTOCOCCUS TOXINS
STREPTOCOCCUS EXOTOXINS
LIPOTEICHOIC ACID
STREPTOCOCCUS EQUI SUBSP EQUI CAUSES
STRANGLES AKA EQUINE DISTEMPER
WHAT IS STRANGLES?
UPPER RESPIRATORY INFECTION WITH ABSCESSATION OF SUBMANDIBULAR AND RETROPHARYNGEAL LYMPH NODES
SWELLING OF THE LYMPH NODES LEADS TO AIRWAY OBSTRUCTION
WHAT AGES OF HORSE DOES STRANGLES INFECT ?
ALL AGES ARE SUSCEPTIBLE BUT YEARLINGS AND WEANED FOALS ESPECIALLY, <4MOS
TRANSMISSION OF STRANGLES
DIRECT- EXUDATES FROM UPPER RESP, DISCHARGING ABSCESSES FROM CARRIER OR INFECTED ANIMAL
INDIRECT- FROM CONTAMINATED BUCKETS/WATER TROUGHS, FEED, STABLES, GRASS, FLIES
STRANGLES COMPLICATION
- GUTTURAL POUCH EMPYEMA
- BASTARD STRANGLES
- PURPURA HEMORRHAGICA
DIAGNOSIS OF STRANGLES
- CLINICAL SYMPTOMS
- CULTURE FROM ABCESS, NASAL SWAB, LAVAGE FLUID
- ELISA
- PCR FOR M PROTEIN
POTENTIAL CARRIERS OF STRANGLES
NEWLY ACQUIRED HORSES
NON AFFECTED IN CONTACT HORSES
AFFECTED IN CONTACT HORSES
WHEN CAN A STRANGLES SUSPECTED HORSE BE RELEASED FROM QUARANTINE?
AFTER THREE NEGATIVE CULTURES
