“…The latter is non‐contagious and occurs through environmental contamination of the udder. Other less common presentations include peritonitis, cystitis/pyelonephritis, endometritis, wound infections and meningitis derived from sepsis (Gay, 1965 ; Besser and Gay, 1985 ; Smith et al, 1985 ; CABI, 2019 ; EFSA AHAW Panel, 2021e ).…”

“…Severe dehydration caused by faecal loss of fluids and electrolytes is a frequent complication of diarrhoea that may result with the development of strong ion (metabolic) acidosis that is accompanied by central nervous system depression, ability to stand and suckling force (Berchtold, 2009).

Escherichia coli ( E. coli ) was identified among the most relevant antimicrobial‐resistant (AMR) bacteria in the EU for dogs and cats, horses, swine, poultry, cattle, sheep and goats in previous scientific opinions. Thus, it has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on its eligibility to be listed, Annex IV for its categorisation according to disease prevention and control rules as in Article 9 and Article 8 for listing animal species related to the bacterium. The assessment has been performed following a methodology previously published. The outcome is the median of the probability ranges provided by the experts, which indicates whether each criterion is fulfilled (lower bound ≥ 66%) or not (upper bound ≤ 33%), or whether there is uncertainty about fulfilment. Reasoning points are reported for criteria with uncertain outcome. According to the assessment here performed, it is uncertain whether AMR E. coli can be considered eligible to be listed for Union intervention according to Article 5 of the AHL (33–66% probability). According to the criteria in Annex IV, for the purpose of categorisation related to the level of prevention and control as in Article 9 of the AHL, the AHAW Panel concluded that the bacterium does not meet the criteria in Sections 1, 2, 3 and 4 (Categories A, B, C and D; 0–5%, 5–10%, 10–33% and 10–33% probability of meeting the criteria, respectively) and the AHAW Panel was uncertain whether it meets the criteria in Section 5 (Category E, 33–66% probability of meeting the criteria). The animal species to be listed for AMR E. coli according to Article 8 criteria include mammals, birds, reptiles and fish.

Digestive disturbances in ruminants: An electromyographic study

1980

View full text Add to dashboard Cite

Motility patterns of the intestine were studied by electromyography in neonate (calf) and adult (sheep) ruminants. The motor effects of spasmolytics and morphinomimetics are described in both health and digestive disturbances (acidosis, parasitism, molasses). In control animals, the electrical activity of the small intestine consisted of two phases of irregular and regular spiking activity, propagated every 2-3 hours along the entire small bowel. The electromyograms of the large intestine exhibited (i) phasic and propagated contractions of the caecum and proximal colon and (ii) tonic unpropagated activity of the spiral colon.In all disturbances investigated, spiral colon activity decreased. The small intes tine motor profile was replaced by a typical minute rhythm in grain overload and strongylosis, a pattern also recorded after an intraduodenal administration of hypertonic solutions. Diarrhea observed in acidosis or molasses (sheep) and of infectious origin (calf) did not disrupt the cyclic activity of the small intestine.The anticholinergic drugs were active in diarrhea by an inhibition of the small intestine activity. By contrast, morphine and synthetic antidiarrheal drugs reduced the diarrhea by enhancement of the actl~v~ty of the spiral colon.
