NPAR=NonProgressive Atropic Rhinitis

agent: toxigenic Bordetella bronchiseptica

PAR=Progressive Atrophic Rhinitis

agent: toxigenic Pasteurella multocida

very contagious disease of swine, caused by Otrhomyxovirus, characterized by fever, muscle stiffness and THUMPS(nopea,pinnallinen hengitys)

-Swine Influenza

bloody diarrhea

-PHE=Porcine Hemorrhagic Enteritis

watery diarrhea

-PED=Porcine Epidemic Diarrhea

zoonotic

-Swine Influenza Virus (SIV) (Orthomyxovirus)
>subtype H1N1(similar to human avian ancestor), H1N2, H3N2

-Streptococcus suis infection

samples(material) and lab : Glasser’s disease(Hp)

-material: from euthanized animals who has not received AB treatment
>swabs from serous membranes
>liquid from serous cavity (e.g. peritoneal fluid)

-in the lab:
>isolation of the agent
>serotyping

cyanosis,

-Streptococcus : yes
-Porcine Proliferative Enteritis: no
-…Gastro..: no
-Porcine Colonic Spirochetosis: no
-Brucellosis: yes
-Glasser’s disease: no
-PRRS Porcine Respiratory and Reproductive Syndrome: yes

PRRS

-Arterivirus
>characterized:
*high piglet mortality and respiratory disease in young pigs

-2 forms:
>Reproductive failure in pregnant gils and sows
*European strain cyanosis of ears, tail, vulva, abdomen and snout
>Respiratory disease pigs at any age
*PRRSV
*common in nursing and weaning pigs

PRRS death usually associated with secondary infections

S. suis

comes Parvovirus infection

true/false

mucohaemorragic diarrhea

-Swine Dysentery (SD) >agent: Brachyspira hyodysenteriae

true / false

host range do not have humans - zoonotic : no - pregnant sows : yes - characterized : vomiting, clinical signs : - no vaccine : false since yes we have vaccine - can use AB's : no (virus)

highest mortality rates of the forms in Porcine Proliferative Enteritis (PPE): - Porcine Intestinal Adenomatosis (PIA) - Porcine Hemorrhagic Enteritis (PHE) - Necrotic Enteritis (NE) - Subclinical

< Porcine Hemorrhagic Enteritis (PHE) > is right highest mortality rates !!!!

causative agent in PPE

-excrete: feces -mode of transmission: intestinal -route of transmission: fecal - oral

Enzootic Pneumonia (=Mycoplasma Hyopneumoniae + secondary bacterial infection: yleensä Pasteurella multocida > tai: Haemophilus parasuis, tai Actinobacillus pleuropneumoniae) false/true

-false -true -false -true -true -false (we do have vaccine) -false (agent : it is bacteria NOT virus) -true (herd morbidity >93%, acute morbidity >100%, ) -false (fomites ei oo) -true (eniten kroonisia, harvoin akuutteja) -true (post mortem: haavaumat apical ja cardiac lung lobes) -there IS vaccine
