Inheritance of lysozyme deficiency in rabbits

The Journal of Heredity
D J Prieur, V M Cámara


The phenotypes of 273 offspring of 56 matings of various genotypes of lysozyme-deficient and normal New Zealand white rabbits were analyzed. It was determined that lysozyme deficiency of rabbits is inherited as an autosomal recessive with complete penetrance. The symbol ld is suggested for the gene for lysozyme deficiency. Further studies on the nature of the condition revealed that the lysozyme deficiency was not due to a lysozyme that was cold labile, or to a lysozyme that was so tightly bound it was unavailable for enzymatic assay, or to a lysozyme with a variant pH optimum. It was demonstrated, however, that the pH profile of the lysozyme remaining in the ld/ld rabbits was different from that found in normal rabbits.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
