Evaluation of acid-base disturbances in calf diarrhoea

The Veterinary Record
C Groutides, A R Michell

Abstract

The severity of acid-base disturbances in diarrhoeic calves was investigated and a simple, inexpensive method of monitoring them was evaluated. The Harleco apparatus measures the 'total carbon dioxide' in a blood sample, mostly generated from the bicarbonate present, and any abnormalities are mainly due to metabolic acidosis or alkalosis. Its performance was tested against a standard blood gas analyser by comparing the results obtained by both methods with nearly 2000 blood samples from healthy or diarrhoeic calves. After technical modifications, the technique gave excellent precision and accuracy for the clinical evaluation of acid-base balance, using venous whole blood. The samples were very stable, especially at 0 degrees C, but also at room temperature. The normal range (mean +/- 1.96 sd) for total carbon dioxide in whole blood from calves was 21 to 28 mmol/litre. For samples corresponding to mild, moderate or severe acidosis, 79 per cent were correctly classified by the Harleco apparatus and only 0.1 per cent were beyond the adjacent degree of severity. After four days of diarrhoea, the calves which later died had twice the deficit in plasma bicarbonate of those which survived. As death approached, the deficit was almost t...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
