Cards in this deck (17)
- 1Describe microscopically BordetellaG-
rods
motile with peritrochous flagella - 2How does it attack sugars?Doesn't because it only needs amino acids for energy.
- 3Samples used for detectionNasal swaps, tracheal aspirates and exudates
- 4Growing conditions37°C for 24-48h on MCC or selective media
- 5Appearance on MACColourless pale colonies
Lac - - 6Selective agars used for Bordetella & their composition?~ Regan-Lowe: charcoal + horse blood+ cephalexin
~ Bordet-Gengou: potato + sheep blood + glycerol - 7Treatment for BordetellaAntibiotics if persistent but not always 100%- can be resistant
- 8Test for bordetellaCat +
Ox +
Motility + except B.parapertussis - 9Name 4 pathogenic speciesB.bronchiseptica
B.avium
B.parapertussis
B.pertussis - 10What does B.avium cause?Bordetellosis in turkey and quails
- 11What is bordetellosis?highly infectious acute upper respiratory tract disease with low mortality but high morbidity.
- 12What is the result after B.parapertussis infection?Less severe pertussis and pneumonia in lambs.
- 13What does B.bronchiseptica cause?1) Atrophic rhinitis in pigs.
2) Canine infectious tracheobronchitis- kennel's cough.
3) Respiratory infections in horses.
4) Pneumonia, bronchitis and laryngitis in cats.
5) URT infection in rabbits.
6) Bronchopneumonia in lab rodents.
= RESPIRATORY PATHOGEN - 14Describe atrophic rhinitisProgressive wasting away or decrease in size (atrophy) of the mucous nasal lining and underlying bone. Bloody sneezing.
- 15What is kennel cough?Attacks the cilia lining the respiratory tract and cause inflammation of the upper airway, leads to irritation of the airways and a dry cough.
It is named kennel cough because it can quickly spread through a kennel and infect every dog. Can be transmitted by aerosols released when a sick animal coughs, by direct contact , or by the sharing of contaminated objects.
Kennel cough causes a persistent cough that may sound as if something is caught in the dog's throat and they are gagging or trying to clear their throat - 16What does B.pertussis cause?Whooping cough-pertussis. Highly contagious. Severe coughing with whoop or gasp sounds so strong that may lead to vomiting or breaking of ribs. Babies may not cough but have periods w/o breathing.
- 17Name important virulence factors for bordetellaFimbriae, tracheal cytotoxin that kills ciliated cells, osteotoxin, LPS, and SOS is DNT- dermonecrotic toxin- induces skin necrosis and impairs osteogenesis, make it easier to break ribs
