Abstract

Visceral larva migrans, a syndrome observed in humans, is caused by larva of parasitic helminths, such as Toxocara spp., which usually infect dogs and cats. Among the risk factors involved in the incidence of this syndrome, the size of these animal populations is particularly important. Ciudad Bolívar (Bolivar State, Venezuela) is a city with a large dog population. This fact has led to an effort to determine of prevalence of eggs from Toxocara spp. and other helminths in public squares and parks in this city. Twenty-five squares and parks were selected from five areas of the city. Soil samples (20 sites) and dog stools (12 sites) were collected from four separate parts of each square or park. Samples were processed by spontaneous sedimentation and saturated sodium solution methods. Among the 70 squares and parks in Ciudad Bolívar, 25 were studied (35,7%). Toxocara eggs were identified in 55% of soil samples and 16.7% of dog stools. Ancylostoma spp. was detected in 61.1% of stools evaluated. There were no differences in helminth detection related to the area of the city where samples were obtained. Public parks and squares in Ciudad Bolívar showed a high percentage of contamination by dog helminths. These results suggest a pote...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.
