Effects of Antibiotic Alternatives on Antimicrobial Resistance Among Fecal Bacteria in Beef Cattle (2020-07-28)Antimicrobial resistance (AMR) represents a growing crisis in both human and veterinary medicine. We evaluated the use of two antibiotic alternatives – heavy metals and essential oils – in beef cattle and their effects on ...
-
(2009-05-15)Type IV collagens are components of basement membranes throughout the body and are involved in maintenance of the structural integrity of tissues as well as cellular differentiation, growth, and adhesion. Members of this ...
-
(2023-05-05)Conserving bighorn sheep (Ovis canadensis) in their native range is challenged by pneumonia epizootics. Mycoplasma ovipneumoniae and Pasteurellaceae family bacteria are strongly implicated in these epizootics. Domestic ...
-
(2012-10-19)Metallic implants called stents are an important part of the treatment of coronary heart disease. While clinical trials are excellent indicators of outcomes, microscopic evaluation of the host tissue response to the implant ...
-
(2009-05-15)Brucellosis is an important zoonotic disease of nearly worldwide distribution. Despite the availability of live vaccine strains for bovine (S19, RB51) and small ruminants (Rev 1), these vaccines have several drawbacks ...
-
(2012-10-19)Although avian influenza virus (AIV) infections in domestic poultry are uncommon, transmission of avian influenza from wild waterfowl reservoirs does occur. Depopulation of the infected flock is the typical response to ...
-
(Texas A&M University, 2006-10-30)Historical data suggests that prolonged survival of Brucella vaccine organisms in the target host enhances immune protection. Recent research has focused upon the development of rough vaccine strains to avoid interference ...
-
(2014-04-15)Despite a large number of studies during the last decade that investigated mucosal immunity in humans, very few works have been done on this immune compartment in lower vertebrates. In the following two studies we focused ...
-
(2022-04-11)After decades of research, the therapeutic mechanism of mesenchymal stem cells (MSC) remains unknown. While most agree that paracrine function is likely, little is known about the influence of cellular or tissue contact. ...
-
(2019-11-13)Salmonella is a leading bacterial pathogen, causing a significant number of human infections and deaths every year in the United States. Recently, the increase in the prevalence of ceftriaxone and azithromycin resistance ...
-
(2018-08-09)Cryptosporidium parvum is a water-borne and food-borne apicomplexan pathogen. It is one of the top four diarrheal-causing pathogens in children under the age of five in developing countries, and an opportunistic pathogen ...
-
Exploring the Molecular Interactions Between Host Cells and Cryptosporidium parvum During Invasion (2018-07-17)Cryptosporidium parvum is a zoonotic protozoan parasite belonging to the Phylum Apicomplexa and a causative agent of mild to severe watery diarrhea in humans and animals. The infection starts with the ingestion of oocysts, ...
-
(2022-10-17)Angelman syndrome is a rare neurogenetic disorder that leads to severe motor deficits, intellectual disability, and seizures. It arises from the loss of expression of the maternal allele of UBE3A in central nervous system ...
-
(2017-04-24)Without feeding success, ticks can neither cause damage nor transmit disease agents to their hosts. From this perspective a deeper understanding of tick feeding physiology has been advocated. Hard ticks such as Amblyomma ...
-
(2013-01-07)Babesia bovis is a causative agent of bovine babesiosis and is transmitted by vector ticks, Rhipicephalus (Boophilus) spp. The disease has a high mortality rate in susceptible cattle, causing serious economic loss. At ...
-
Extensive investigation of reticuloendotheliosis virus in the endangered Attwater's prairie chicken (Texas A&M University, 2007-09-17)Reticuloendotheliosis virus (REV) is a retrovirus that causes a neoplastic disease in a wide range of avian hosts including chickens, turkeys, and ducks. In 1993, REV was detected in the endangered Attwater's prairie ...
-
(2011-02-22)Although wild birds are natural hosts of avian influenza viruses (AIVs), these viruses can be highly contagious to poultry and a zoonotic threat to humans. The propensity of AIV for genetic variation through genetic shift ...
-
(2018-07-03)The adaptive immune system is responsible for an antigen-specific response that is stronger and faster with each subsequent infection. The hallmarks of this response are the B cell and the T cell, which are responsible for ...
-
(2015-11-23)The rotavirus enterotoxin, NSP4, is responsible for early secretory diarrhea associated with rotavirus infection and is critical for RV replication and morphogenesis. NSP4 interacts directly with caveolin-1 and cholesterol ...
