For the last few decades, meat consumption in the United States has increased dramatically and so did the rest of the world. On average, Americans consume at least 270 pounds per person a year, which is way more than almost other country on the planet (Barclay, 2012). In just a short period of time, our meat consumption today has triples if not quadruples the level of meat consumption in the 1900s. During World War I period, meat counters and farm owners were struggled to keep up with demands, which in return left Americans no choice but to pay above market prices for meat products (Barclay, 2012). This prompted scientists and meat-producing companies to try various new feeding methods to keep up with the demands and produce high quality meat products with minimal costs, but they all came up short. It wasn’t until the 1940s that scientists discovered that using low dose of antibiotics in animal feeds could cure various fatal scourges in animals (Ogle, 2013). Not only did antibiotics provided the answer for diseases in livestock animals, it also helped to accelerate animal growth and enhance animal production. Since then, meat-producing companies and farm owners have doubled the usage of antibiotics in animal feeds. This feeding method has proven to be instrumental in the meat-producing industry as it is considered to be one of the reasons that allowed the U.S to have such a high level of meat consumption nowadays. Despite its benefits to the agriculture industry, health…

Linezolid, chemically (S)-N-({3-[3-fluoro-4-(morpholin-4-yl)phenyl]-2-oxo-1,3-oxazolidin-5-yl}methyl)acetamide, a synthetic antibiotic belong to a new category of antimicrobials called the oxazolidinones. Linezolid disrupts bacterial expansion by inhibiting the initiation process in protein synthesis. Distinctively, linezolid binds to a site on the bacterial 23S ribosomal RNA of the 50S subunit and prevents the bargain of a resourceful 70S initiation multifaceted, which is an essential section…

approved by the FDA in June 2014 as a second-generation oxazolidinone with potentially four- to 16-fold potency against MRSA when compared to linezolid.1 Favorable results from clinical trials have led to its indication for the treatment of ABSSSIs in adult patients with susceptible bacteria.1 Tedizolid phosphate is a prodrug that is converted by plasma phosphatases to its active form. It interacts with the bacterial 23S ribosome initiation complex and binds to the 50S subunit to…

Pneumonia is quite the serious illness, at least, it can be. As such, it's prudent for everyone to know about the disease as much as they can. Here are more facts about pneumonia that everyone should know. Number Eight: Speech-Language Pathologists Are Innaccurate Speech-language pathologists who evaluate clients with the disease fail to identify nearly half of patients who have the illness. This is due to something known as silent symptoms. Number Seven: Aspirated Substances of Pneumonia…

they are in the lumen of the bronchi. They are not invasive endothelial cells. I really don’t make the distinction usually. I think most of our infections are airway infections. Interviewer: What about the importance of addressing bacteria biofilms? Dr. Nick: I think it is a very important issue. We don’t have any specific approach that differs at this time, but if we had one it would be of interest. Interviewer: Do concerns around antibiotic resistance ever influence your choice of…

But in 2002, the first case of complete resistance to this drug was reported. (Talaro, 2008, p.375). New treatments for MRSA are needed. Older antibiotics mention earlier such as Trimethoprim, Sulfamethoxazole, Tetracyline and clindamycin are being reexamined and used to treat infections successfully. New treatment options for MRSA infections include linezolid, quinupristin, dalfopristin, daptomycin and tigecycline. All of these antibiotics except for linezolid require IV administration. There…

Choice “E” is the best answer. This patient has nocardiosis. Trimethoprim-sulfamethoxazole antibiotic therapy inhibits bacterial growth by inhibiting successive steps in the synthesis of dihydrofolic acid. Sulfonamides have long been the first-line antimicrobial therapy for nocardiosis. Among the sulfonamides, sulfadiazine is generally preferred because of its CNS and CSF penetration. Trimethoprim-sulfamethoxazole (TMP-SMZ) is considered the therapy of choice by most authorities. Choice “A”…

Standards Institute criteria. Results: From a total of 359 patients, who were required invasive ventilation for longer than 48 hours and hospitalised in the ICU, VAP was determined in 16 cases. VUR was 65%, VAP ratio was 4.5% and the rate of VAP was 3.3 per 1000 ventilator days. Seventeen microorganisms were isolated from endotracheal aspiration samples, including Acinetobacter baumannii (n=6), Pseudomonas aeruginosa (n=4), methicillin-resistant Staphylococcus aureus (n=4), Klebsiella…

Her primary care provider manages her on this medication. There are a total of seven medications that are contraindicated while taking phentermine and these include iobenguane I 123, isocarboxazid, linezolid, phenelzine, procarbazine, selegiline transdermal, and tranylcypromine (Medscape, n.d.). Phentermine has many side effects and the most common include paresthesia, dry mouth, constipation, upper respiratory infection metabolic acidosis, headache, and nasopharyngitis (Medscape, n.d.). It is…

pseudomonal strains (with a > 10% resistance). Once cultures are available these patients should be treated based on the microbiologic data obtained from on respiratory samples obtained noninvasively. Empiric Therapy: VAP Causative organisms most commonly associated with VAP in the US are seen to be S. aureus, P. aeruginosa, enteric gram-negative bacilli, and Acinetobacter baumannii . About 50% of S. aureus isolated were MRSA. All patients with VAP are recommended MRSA coverage if they are…
