CHOOSE THE BEST ANSWER FOR EACH QUESTION The figure below is from a study testing how antibiotic treatment affects the post-treatment colonization rate of pathogens in the human gut. Antibiotics are often general in their effect and kill harmful and beneficial bacteria alike, including our gut microbiome. The researchers focused on the bacterial pathogen C. difficile, which can cause serious inflammation of the colon and even death if untreated. The figure shows the colonization rate of the C. difficile pathogen after patients had finished their antibiotic treatment. The figure compares three groups: patients who received “low”, “medium”, and “high” levels of the antibiotic. What major benefit of having a healthy microbiome is supported by the results in the figure below? Our gut microbiome is an example of a/an relationship.  

Which of the following is correct regarding proteases?

The veterinarian runs the following diagnostics be run on Rumpy; CBC: Total WBC: 26,000 cells/mm3 (ABOVE NORMAL), Granulocytes: 21,900 cells/mm3 (ABOVE NORMAL), Lymphocyte: 4,000 cells/mm3 (ABOVE NORMAL), Monocyte 800 cells/mm3 (ABOVE NORMAL), all other values WNL. CHEM: Albumin: 1.624 g/dl (BELOW NORMAL), Globulin: 5.517 g/dl (ABOVE NORMAL), Total bilirubin: 1.88 mg/dl (ABOVE NORMAL), Blood Urea Nitrogen : 37.8 mg/dl (ABOVE NORMAL), Creatinine: 3.56 mg/dl (ABOVE NORMAL), all other values WNL. LYTES: Phosphorus : 2.4 mmol/L (ABOVE NORMAL), Sodium : 123 mmol/L (BELOW NORMAL), Potassium : 3 mmol/L (BELOW NORMAL), Chlorine : 93 mmol/L (BELOW NORMAL), all other values WNL. Canine Parvo SNAP Test: Negative Canine Lepto SNAP Test: POSITIVE Fecal Test : Negative 3-View Abdominal Radiographs: Shows no signs of any foreign bodies or other abnormalities.   The veterinarian concludes that Rumpy likely has an active Leptospirosis infection due to positive Lepto SNAP results, the elevated WBC, additionally he is azotemic, hyperbilirubinemic, and has multiple electrolyte imbalances. 

The veterinarian performs her exam on Rumpy, and determines he is ~7% dehydrated, today’s contemporary fluid losses are estimated at 500 mL, otherwise Rumpy shows no other outward clinical signs.   Her DDx List includes: Canine Parvovirus Leptospirosis Lyme Disease Endoparasites Foreign Body Ingestion Toxin Ingestion Pancreatitis Gastroenteritis

Calculate Rumpy’s maintenance requirement.  Maintenance fluid requirements for canines: (40 – 60)mL/kg/24hr
