25
The dilated lymphatic ducts (left) and lacteals within villi (right) combined show: | Cause **Protein Losing Enteropathy**
Lymphangiectasia
26

Typhlocolitis
28
Inflammation of rectum
Proctitis
29

30
Inflammation of small intestine (just ileum)
Ileitis
31
Definition of diarrhea:
Secretion of **abnormally fluid feces** accompanied by * **increased volume** of feces * **increased frequency** of defecation
32
What are the 4 basic mechanisms of diarrhea?
1. Hypersecretion 2. Malabsorption/Maldigestion 3. Exudation/Effusion 4. Dysmotility
33
The normally functioning villi should possess:
* intact microvilli * tall columnar villus enterocytes * crypt epithelium (progressive differentiation up the villi)
34
Pathogen associated with hypersecretion diarrhea
**ETEC** * ENTEROTOXIN activates cAMP/cGMP -> FLUID SECRETION
35
# True/False Malabsorptive/Maldigestive diarrhea is a passive process via osmosis.
True
36
Intestinal causes of Malabsorptive/Maldigestive diarrhea
* microvillus damage/destruction * absorptive enterocyte necrosis/loss * crypt cell necrosis/loss * crypt hyperplasia -> epithelial attenuationl
37
Pathogens associated with **microvilli damage/destruction** in **Malabsorptive/Maldigestive diarrhea**
* **AEEC** * **Cryptosporidium**
38
Pathogens associated with **villus enterocyte necrosis** in **Malabsorptive/Maldigestive diarrhea**
* **Enteric Coronaviruses** - pigs (TGE), calves, cows, horses * **Enteric Rotavirus** * **Coccidia Protozoans**
39
Pathogens associated with **crypt cell necrosis** in **Malabsorptive/Maldigestive diarrhea**
**Radiomimetic Viruses** * **Canine & Feline Parvoviruses (FPLV)** - immunosuppression, diptheritic membranes, septicemia, SLOW regeneration, teratogenic effect (cerebellar hypoplasia) * **Bovine Viral Diarrhea Virus (BVDV)**
40
Key histological features of FPLV
* crypt necrosis * villus blunting & fusion * crypt regeneration
41
Pathogens associated with **crypt hyperplasia** in **Malabsorptive/Maldigestive diarrhea**
* **Lawsonia intracellularis** - proliferative enteritits, mucosal thickening
42
Pathogens associated with **villus enterocyte necrosis AND lamina propria damage** in **Exudative/Effusive diarrhea**
* **Salmonella** - zoonotic, virulence factors (flagella, fimbriae, LPS, endotoxin) * **Clostridium perfringens & C. difficile** - horses | Diptheritic membrane
43
Conditions associated with **lymphatic obstruction (PLE) / infiltrative disease** in **Exudative/Effusive diarrhea**
* **Mycobacterium avium paratuberculosis (Johne's Disease)** - granulomatous inflammation, protein losing-enteropathy (PLE) * **Lymphoma** - neoplastic infiltrates
44
What pathogen of cattle features gross lesions with thickened, **"corrugated" mucosa**, mucosal erosions, and **mesenteric lymphadenitis**. Histologically you will see **intracellular acid-fast bacilli**.
Mycobacterium avium paratuberculosis (Johne's Disease)
45
Dysmotility where there is **decreased contact time** with mucosa, leading to **maldigestion/malabsorption**
Hypermotility
46
Dysmotility where there is **bacterial overgrowth**, leading to toxic substance production/reduced fermentation, and secondary secretory or osmotic diarrhea.
Hypomotility
