Y. enterolitica are the most common species causing human enteric (intestinal) yersiniosis. Pigs are the major animal reservoir for the few strains of Y. enterocolitica that cause human illness, but rodents, rabbits, sheep, cattle, horses, dogs, and cats also can carry strains that cause human illness.

Untreated plague can progress to a fulminant illness with a high risk of mortality. Thus, early and appropriate antibiotic treatment is essential. Historically, streptomycin (15 mg/kg, up to 1 g intramuscularly every 12 h) has been the drug of choice ; however, in the United States, supplies of streptomycin are scarce.

Summary
This report provides CDC recommendations to U.S. health care providers regarding treatment, pre-exposure prophylaxis, and postexposure prophylaxis of plague. Yersinia pestis, the bacterium that causes plague, leads to naturally occurring disease in the United States and other regions worldwide and is recognized as a potential bioterrorism weapon.
Introduction
Yersinia pestis, the causative agent of plague, is a nonmotile, gram-negative coccobacillus that persists in the natural environment in sylvatic cycles. Sporadic epizootics can sicken large numbers of rodents and other mammals and spill over to incidental hosts, including humans ( 1 ). Y.
Methods
CDC developed these guidelines after reviewing existing data on treatment and prophylaxis of plague, collecting and summarizing additional evidence, and gathering input from approximately 90 experts in numerous fields, including infectious diseases, emergency medicine, pharmacology, neonatology, obstetrics and gynecology, geriatrics, microbiology, epidemiology, and crisis standards of care.
Recommendations
Since the publication of plague guidelines in 2000, FDA has approved ciprofloxacin, levofloxacin, and moxifloxacin for treatment and prophylaxis of plague in humans on the basis of the Animal Rule ( 49 ).
Future Directions
Future efforts should attempt to address remaining gaps in the prevention, recognition, and clinical management of plague. Emergency preparedness should include planning for bioterrorism events that could exhaust U.S. antimicrobial, ventilator, and other supplies in clinical settings and in stockpiles.
Limitations
These guidelines are subject to at least three limitations. First, many of the recommendations are based on systematic review data derived from case reports and case series, both of which are widely recognized as low quality and biased sources of data.
Conclusion
Plague has a high case-fatality rate but is treatable with antimicrobials and supportive care. Thus, early recognition of disease and administration of effective antimicrobials to treat plague are paramount to saving lives. In addition, persons exposed to Y. pestis can avoid illness if given effective antimicrobial prophylaxis in a timely manner.
What antibiotics are given for the plague?
You'll receive powerful antibiotics, such as: Gentamicin. Doxycycline (Monodox , Vibramycin , others) Ciprofloxacin (Cipro) Levofloxacin. Moxifloxacin (Avelox) Chloramphenicol.

What Disease Is Caused byYersinia pestis
- The bacteriumYersiniapestilenceit causes bubonic plague, also popularly known as black plague and can be found in fleas, which are present mainly in infected rodents. This disease is serious and often fatal if it is not treated immediately, being the main responsible for the death of more than 30% of Europe's population in the 14th century.
Bacteria Life Cycle
- Fleas feed on blood, especially rodents. If the rodents are infected withYersinia pestis, when parasiting the animal, the flea also acquires this bacterium. When the rodent dies, the infected flea looks for other bodies to continue feeding on blood. Thus, it can infect other rodents and other animals, such as cats or humans through bites. Each flea can remain infected for months and th…
How The Transmission Happens
- The transmission of this bacterium to humans can occur in several ways, such as: 1. Infected flea bite; 2. Manipulation of blood, secretion or tissues of infected animals; 3. Bites and scratches from contaminated cats. The least common way of transmission is through vomiting, sneezing and coughing, in which the droplets are dispersed in the air and can spread this bacteria among …
How to Prevent
- Prevention for this infection can be done based on rodent and pest control and the use of repellents to prevent flea bites, since the plague-causing bacteria mainly infect rats, mice and squirrels, which are the main hosts of fleas . It is also important to wear protective equipment when handling blood, secretion and tissues from potentially infected animals. People who travel …
