Bacterial diseases plague

Many antibacterial agents are now available and the vast majority of bacterial diseases have been brought under control (e.g. syphilis, tuberculosis, typhoid, bubonic plague, leprosy, diphtheria, gas gangrene, tetanus, gonorrhoea).

Differential Diagnosis Q fever usually presents as an undifferentiated febrile illness, or a primary atypical pneumonia, which must be differentiated from pneumonia caused by mycoplasm, Tegionnaires disease, psittacosis or Chlamydia pneumoniae. More rapidly progressive forms of pneumonia may look like bacterial pneumonia including tularemia or plague. 

Resistance to tetracyclines shows marked inter-regional variations and changes rapidly with time. The selection of resistant bacterial strains may be favored by widespread, often prophylactic, use in veterinary medicine and by long-term therapy for acne, periodontal disease, or symptomatic Borrelia infections. Many of the documented cases of resistance are of limited practical significance, since the tetracyclines are merely one of a number of therapeutic alternatives. The problem may be different when these drugs are the chemotherapeutic agents of first choice, that is in chronic Borrelia infections, especially arthritis due to Lyme disease and pulmonary or bubonic plague due to Yersinia pestis (154). 

If we were to have over the next three or four or five years recurring plagues of widespread different diseases of different sorts, if our crops were to be affected by bacterial agents, if we were to be continually in a state of suspense, not knowing what disease was going to descend upon us next, obviously our industrial progress and our very civilization would be shaken and we would slide backwards, while our opponents moved forward. 

Tularemia (francisella tularensis), also known as rabbit fever, deerfly fever, and Ohara s disease, like the plague, is a bacterial infection that can occur naturally from the bite of insects, usually ticks and deerflies. The disease can also be acquired from contact with infected rabbits, muskrats, and squirrels, ingestion of contaminated food, or inhalation of contaminated dust. Once contracted, it is not directly spread from human to human. Tularemia remains infectious in the blood for about 2 weeks and in lesions for a month. It remains ineffective in deerflies for 14 days and ticks throughout their lifetime (about 2 years). The disease can occur at anytime of the year, but is most common in the early winter during rabbit hunting season and in the summer when tick and deerfly activity is at its peak. Tularemia contracted naturally has a death rate of approximately 5%. 

After this time, plague became established in the countries bordering the eastern Mediterranean Sea.2 In 430 bc, Sparta won the Peloponnesian War partly because of the plague of Athens.3 Some scholars believe that this was the bubonic plague, but others suggest that it may have been due to other bacterial or viral diseases.4...
