Innovative Methodology for Antimicrobial Susceptibility Determination in Biofilms.

spp. are facultative pathogens that contribute to the pathogenesis of multiple bovine diseases, including the bovine respiratory disease complex, and have been shown to form biofilms. Biofilm formation is associated with increased antibiotic resistance in many organisms, but accurate determination of antimicrobial susceptibility in biofilms is challenging.

Negevirus Piura Suppresses Zika Virus Replication in Mosquito Cells.

We investigated the interaction between the insect-specific virus, Piura virus (PIUV), and the arbovirus Zika virus (ZIKV) in cells. We performed coinfection experiments in C6/36 cells. Piura virus (Cor 33 strain, Colombia) and ZIKV (PRVABC58 strain, Puerto Rico) were co-inoculated into C6/36 cells using two multiplicity of infection (MOI) combinations: 0.

Comparison of West Nile Virus Disease in Humans and Horses: Exploiting Similarities for Enhancing Syndromic Surveillance.

West Nile virus (WNV) neuroinvasive disease threatens the health and well-being of horses and humans worldwide. Disease in horses and humans is remarkably similar. The occurrence of WNV disease in these mammalian hosts has geographic overlap with shared macroscale and microscale drivers of risk.

Experimental Infection of Mid-Gestation Pregnant Female and Intact Male Sheep with Zika Virus.

Zika virus (ZIKV) is an arbovirus that causes birth defects, persistent male infection, and sexual transmission in humans. The purpose of this study was to continue the development of an ovine ZIKV infection model; thus, two experiments were undertaken. In the first experiment, we built on previous pregnant sheep experiments by developing a mid-gestation model of ZIKV infection.

Strain-Dependent Activity of Zika Virus and Exposure History in Serological Diagnostics.

Zika virus (ZIKV) circulates as two separate lineages, with significant genetic variability between strains. Strain-dependent activity has been reported for dengue virus, herpes simplex virus and influenza. Strain-dependent activity of subject specimens to a virus could be an impediment to serological diagnosis and vaccine development.

Experimental Infection of Pregnant Female Sheep with Zika Virus During Early Gestation.

Zika virus (ZIKV) is a vertically and sexually transmissible virus resulting in severe congenital malformation. The goal of this study was to develop an ovine model of ZIKV infection. Between 28-35 days gestation (DG), four pregnant animals were infected with two doses of 6 × 10 PFU of ZIKV; four control animals received PBS.

Consequences of perinatal infections with rubella, measles, and mumps.

Measles, mumps, and rubella have recently taken the stage as re-emerging diseases of public health importance-particularly in regards to the consequences seen with perinatal infections. Effective vaccination strategies have successfully reduced the spread of measles, mumps, and rubella in the United States, but a current trend of increased vaccination hesitancy, fear of vaccine safety, and spread of misconceptions surrounding the science of vaccines have led to a relative resurgence of these diseases in the developed world. This article aims to explore why measles, mumps, and rubella should continue to be on the radar of medical professionals, and why the study of these diseases is important for understanding other teratogenic viruses of public health importance.
