Abstract

Over a period of approx. 15 months, post-mortem (PM) examinations were made on genital organs (34 gilts and 81 sows) from a sow-pool with reproductive disturbances. Anamnestic data on the animals included information about parity number, date of farrowing, dates of weaning, oestrus and service, and cause of culling. At the PM examination, the macroscopic appearance of the ovaries (follicles, corpora lutea, cysts) and uterus (content, endometrium) were studied. Specimens from the endometrium was examined histologically. The most common reason for culling was repeat breeding (67%), in most cases at irregular intervals. The non-productive period averaged 82 days in sows (weaning to slaughter) and 151 days in gilts (from 1st day of mating until slaughter). In 49.6% of the sows no pathological changes were found. Macroscopic examination of the ovaries in 108 animals showed that 69% were cycling normally, 17% were anoestral and 14% had multiple follicular cysts (7 animals were not included due to ovo-testis [1 case], pregnancy [3 cases] and with signs of recent abortion [3 cases]). As judged from the histological examination, 27% of the animals had endometritis, which was classified as mild in 50% of them. Anoestral animals had a hig...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.
