Reevaluating fecal microbiota transplantation for recurrent clostridium difficile infection
… a disease associated with the wide-spread use of antibiotics and causes 450,000 infections and almost 30,000 deaths in the United States annually. Recurrence is a major problem, with approximately 1/3rd of patients relapsing after antibiotic treatment for CDI. Fecal Microbiota Transplantation …

The role of the cytochrome B and cytochrome C oxidase III genes in the immune response of the South African abalone, Haliotis midae
… being viewed as an alternative to chemical and antibiotic treatments (Balcazar et al., 2006), and have been shown to improve the health of the South African abalone, Haliotis midae (Macey and Coyne, 2005). In order to establish better health management systems, and to implement alternative …

Dye Marking of Antibiotics Used in Treatment of Mastitis
… mastitis 1.5 times per year (74). The minimum antibiotic treatments per case of mastitis is two; with approximately 11 million dairy cows in the United States, the annual minimum number of antibiotic treatments is 33 million. In South Dakota, with nearly 160 thousand dairy cows, the number of …

Large-scale prediction of patient-level antibiotic resistance : towards clinical decision support for improved antimicrobial stewardship
Antibiotics are critical to modern medicine. However, levels of resistance have been rising, exacerbated by over-prescription and misuse of antibiotics. One major reason for this inappropriate usage is that doctors often must decide treatment without the results of microbiologic testing, a setting …

A retrospective evaluation of antimicrobial management among patients with sepsis in Intensive Care Unit (ICU) at Gaborone Private Hospital in Botswana
… though a substantial proportion of empirical antibiotic treatments are confined to standard guidelines, utilization of local guidelines was associated with an increased odds of death, which requires further study and evaluation. (OR 3.68, CI 1.28-10.6, p=0.012), The study underscores the …

FUNCTIONAL FEED ADDITIVES FOR ANIMAL HEALTH
… spreading. In livestock, the highest use of antibiotic treatments is recorded in young animals, due to their immature immune system, and the presence of several stress sources that predispose young animals to develop multifactorial diseases, particularly from gastrointestinal origin, that …

MAPPING GENOMIC VARIANTS ASSOCIATED WITH FUNCTIONAL AND HEALTH TRAITS IN DAIRY CATTLE POPULATION
… to the temporal relationship between veterinary treatments and perturbations. This classification revealed clear differences in resilience indicators across categories. By aligning perturbation profiles with treatment timing (before, during, or after perturbations), the study showed that …

Biofilm Removal with Acoustic Cavitation and Lavage
… implants, and surrounding tissues resist to antibiotic treatments, prolong hospitalization, increase mortality, and usually require the removal and replacement of the entire joint. Through acoustic cavitation, it could be possible to remove the biofilm colonies from the infected surface, thus …

Metagenomic Analysis of Antibiotic Resistance Genes in the Fecal Microbiome Following Therapeutic and Prophylactic Antibiotic Administration in Dairy Cows
The use of antibiotics in dairy cattle has the potential to stimulate the development and subsequent fecal dissemination of antibiotic resistance genes (ARGs) in bacteria. The objectives were to use metagenomic techniques to evaluate the effect of antibiotic treatment on ARG prevalence in the fecal …

Synergistic Effects of Monoculture Biofilm Dispersion and Antibiotic Treatment
… state, bacterial cells are less susceptible to antibiotic therapy. However, once released from a biofilm, antimicrobial susceptibility returns. In an aim to increase antibiotic efficacy of CAUTI treatment, uropathogenic Pseudomonas aeruginosa PAO1 and Escherichia coli F11 biofilms were cultured …

Settlement of marine fouling organisms in response to novel antifouling coatings
… immersion in the sea or in seawater aquaria. Antibiotic treatments showed that this change in surface appearance was due to biological (microbial) activity. Bacteria appear to remove the amorphous phase from the surface of the paraffin waxes, revealing an underlying crystalline phase, which is …

Controlling Pseudomonas aeruginosa Persister Cells by Human Granulocyte Macrophage Colony-Stimulating Factor
… These mechanisms allow bacteria to exhibit antibiotic tolerance and relapse to an active virulent state when the antibiotic treatments are discontinued. During bacterial invasions, the host immune cells secrete special signaling proteins, known as cytokines which orchestrate events leading …

Culture-independent identification of gut bacteria in fourth-instar red imported fire ant, Solenopsis invicta Buren, larvae
… species are in the guts of larvae followed by antibiotic and microscopy work to further study their roles in the ants. The composition of the bacterial community in fire ant larvae was described with culture-independent methods utilizing 16S rDNA sequencing. The 16S rRNA gene was directly …

A mechanistic understanding of the postantibiotic effect and treatment strategies
<p>Although antibiotics have proven to be one of the great achievements of modern medicine, their efficacy has dramatically decreased over the past several decades. This is due, in part, to the rapid pace of natural bacterial evolution, but also to the overuse and misuse of antibiotics in general. …

Detection of Antibiotic Residues in Bovine Milk
<p>Under the Food, Drug, and Cosmetic Act antibiotics are considered as ·adulterants in milk and milk products. Cultured dairy products cannot be made with milk containing small concentrations -of antibiotics. Also, minute quantities of antibiotics cause allergic reactions in some people. …

Design and Discovery of Novel Bacteriocins
… of Penicillin in 1928, global demand for antibiotics has continued to grow year after year. Despite our reliance upon them, few new classes of antibiotics have been discovered since the 1980’s. Our existing arsenal of therapeutics have been systematically overused and misused, driving the …

Evaluation of serum protein-based arrival formula and serum protein (Gammulin) on performance, morbidity, and mortality of stressed (transport and cold) male dairy calves
… randomly assigned to 1 of 4 treatment groups. Treatments were 1 = control electrolyte, milk replacer without G (E; n = 25); 2 = AF, milk replacer without G (AF; n = 22); 3 = control electrolyte, milk replacer with G (EG; n = 24); and 4 = AF, milk replacer with G (AFG; n = 22). At arrival, …

Duration of Antibiotic Residues in Milk from Cows Treated via Intrauterine and Intramammary Infusion
<p>Antibiotics have been employed by farmers and veterinarians for treatment of infectious cattle diseases for over 3 decades. The most common of these diseases in dairy cows is mastitis. Mastitis is defined by the National Mastitis Council (NMC) (49) as an inflammation of the mammary gland. It is …

A New Class of Antibiotic That Prevents Drug Tolerance, Persistence, and Resistance By Controlling Emergence of Phenotypes.
… against bacterial infections and innovations in antibiotic therapy has never halted throughout human history. However, bacteria have evolved smartly and resistance against practically all conventional antibiotics has been developed. Furthermore, bacteria can form biofilms, which are …

Abundance of Antibiotic Resistance Genes in Feces Following Prophylactic and Therapeutic Intramammary Antibiotic Infusion in Dairy Cattle
Prophylactic and therapeutic antibiotic treatments have the potential to increase excretion of antibiotic resistance genes (ARGs) by dairy cattle through selection pressure on the gut microbiome. The objective of these studies was to evaluate the effect of cephapirin benzathine administered …
