Abstract

Studied were a total of 14,944 samples of minced meat for the presence of Salmonellae and 608 samples for establishing the coli-titer. Examined were also bacteriologically 5651 washing samples from the workers' hands, the machines, equipment and stock implements in the shops for the production of minced meat prior to starting work as well as 3721 washing samples from the same for the presence of coliforms. It was found that 1.81 per cent of 14,188 samples of minced meat were contaminated with as many as 17 serotypes of Salmonella organisms belonging to the B, C and E serogroups. It was believed that the primary source of Salmonellae in minced meat were the clinically normal Salmonella carrier animals apart from the occasional contamination during the individual technologic stages of processing. The smallest amount of minced meat in which coli bacteria (titer) could be found varied within the range of 0.01 to 0.0001, 53 out of the investigated 608 samples, i. e. 8.72 per cent showing a titer of 0.01, 477 samples (78.45 per cent) having a titer of 0.001, and 78 samples (12.88 per cent) having a titer of 0.0001. Of the examined samples washings 25.69 were positive for coli bacteria, and 0.27 per cent--for Salmonella bacteria, whic...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.
