Abstract:
Experiments were conducted to investigate the colonic temperature (TC) response to Alcaligenes faecalis infection in turkeys. One-day-old poults were inoculated intranasally with 0.05 ml of a 24 hour brain heart infusion (BHI) broth culture with a bacterial concentration of 1.0 x 10(9) cells/ml. Within 2 hours after inoculation TC was depressed significantly in challenged poults. This depression was significant through day 14 in experiment 1 and day 6 in experiment 2. Further studies with sterile BHI broth, BHI broth culture supernatant and phenol killed bacteria indicated that TC depression occurred only with the killed bacteria. This TC depression with killed bacteria lasted 3 days. Foot pad temperature (TF), an indicator of peripheral vasomotor tone, was depressed through day 9 in A. faecalis-infected poults. The reduced TC and TF of infected poults is highly suggestive of a reaction to an endotoxin in young birds. The mechanisms whereby A. faecalis allows poults to become more susceptible to other infective agents may reside in physiological changes leading to reduced body temperature.

Assessing Body Temperature - Rectal
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...
Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
Assessing Body Temperature - Axilla
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...
