For over two thousand years, bloodletting was a standard treatment for almost any ailment, including infectious diseases. In an attempt to alleviate symptoms, bloodletting practitioners used various instruments to withdraw blood from patients, including syringes, lancets, and even leeches.
What were antibiotics first used for?
In 1909, he discovered that a chemical called arsphenamine was an effective treatment for syphilis. This became the first modern antibiotic, although Ehrlich himself referred to his discovery as 'chemotherapy' – the use of a chemical to treat a disease.
Was Salvarsan the first antibiotic?
Salvarsan, an arsenic-based chemical discovered by Ehrlich and his team in 1909, proved an effective treatment for syphilis and was probably the first truly modern antimicrobial agent, though it was not an antibiotic in the strict sense of the word.
Which drug is used as a antibacterial drug?
Gentamicin and tobramycin are used most commonly and are the primary agents used to treat infections caused by gram-negative rods, most notably Pseudomonas species. Although most antibiotics that inhibit protein synthesis are bacteriostatic, the aminoglycosides are frequently bactericidal.
Are antibiotics systemic treatment?
Background: Systemic antibiotics are used in a targeted fashion, i.e. according to antibiogram whenever possible, otherwise in a calculated or empiric way. The pathogen to be treated can be identified sometimes by the clinical symptoms (e.g. in classical erysipelas) or by microbiological analysis.
What is the best medicine for bacterial infection?
Bacterial infections are treated with antibiotics such as amoxicillin, erythromycin and ciprofloxacin. There are many different types of antibiotic, with different ways of working; the choice depends on the type of infection you have.

Unfortunately, antibiotics' effectiveness has caused them to be massively overprescribed and misused as well.
Who first suggested viruses as a killer?
The idea of using viruses as bacteria killers actually was first suggested by a British bacteriologist, Ernest Hankin, who theorized in 1896 that some sort of a microbe in the waters of the Ganges and Jumna rivers in India was limiting the spread of cholera.
Why was Guaiacum so popular?
Guaiacum became so popular that a conspiracy theory developed that doctors weren't prescribing it because it might cure patients and cut physicians' income. It became even more expensive because the Holy Roman Emperor Charles V. awarded an importation monopoly to the banking house of Fugger.

Experiments show that honey actually has such powerful antimicrobial abilities that it can kill wound bacteria in less than two days on average, and in some cases as quickly as 10 hours after application — performance that rivals modern antibiotics.
Why did doctors give people garlic?
In the early 1900s, doctors gave people garlic during influenza outbreaks as a protective medicine. The belief in garlic's powers was so strong that during the flu epidemics of 1917 and 1918 in the U.S., some people wore necklaces of garlic around their necks when they went out in public.

At the same time antibiotic resistant bacteria that survives antibiotic treatment are becoming more and more common, making available antibiotics ineffective. Thus, we are inevitably facing a major health problem. Read more about the problems with antibiotic ...
What are the characteristics of topical antibacterial drugs?
Characteristics of topical ophthalmic antibacterial drugs to consider are the spectrum, and their lipid versus water solubility, with lipid solubility being more important if tissue penetration is of importance. Because of the ability to administer high concentrations of antimicrobials with topical administration, traditional classification of bacteriostatic versus bactericidal (fungal or viral -static or -cidal) may not be relevant to antiinfective drugs, and susceptibility data might underestimate topical efficacy. Ophthalmic drugs indicated for treatment of ocular infections are available as single or multiple antimicrobial agents (Table 8-2a and Table 8-2b ). Generally, either gram-negative or gram-positive organisms are targeted using individual agents; mixed infections can be targeted with combination products or drugs characterized by a broad spectrum. Whereas few drugs are approved for use in animals, multiple human products are commercially available. Others can be compounded, which might include “fortification” of commercial products. However, the nuances of ocular preparations mandate that extreme caution be taken when formulating or modifying a product intended for topical ocular therapy (see Chapter 23 ). 11
What is the best treatment for bacterial meningitis?
Because of the harm associated with inflammation in a closed system, antiinflammatories should be considered when treating CNS infections (e.g., meningitis). Corticosteroid therapy may be indicated during initial stages of treatment of meningitis to minimize the effects of inflammation and loss of capillary integrity. 2,7 Experimentally, methylprednisolone decreases leukocyte accumulation, CSF outflow resistance, and brain water content in animals with bacterial meningitis. 2 Dexamethasone also reverses the development of brain edema and, compared with methylprednisolone, has the added advantage of decreasing CSF pressure and lactate. Note that these studies did not include comparisons with antimicrobial therapy. Nonetheless, glucocorticoid therapy may be beneficial early during the course of therapy; indeed, treatment before antibacterial therapy may minimize the effects of mediators of inflammation released by dying bacteria. 2 A study of infants with bacterial meningitis treated with ceftriaxone and either a placebo or dexamethasone found the duration of infection and degree of inflammation in the latter group to be shorter and less, respectively, although mortality or long-term neurologic sequelae did not differ between the two groups. 8 In an analysis of five clinical trials in adult humans with bacterial meningitis, the incidence of side effects was the same in the group treated with glucocorticoids (dexamethasone), but both mortality and persistence of clinical signs were improved in the group treated with steroids, leading the authors to conclude that a single dose is justified if given at the beginning of antimicrobial therapy. 9,10 Dexamethasone can be used (0.1 to 0.15 mg/kg every 6 hours up to 4 days), particularly in the presence of cerebral edema. 2
What is the most common bacterial conjunctivitis in dogs?
The most common organism associated with bacterial conjunctivitis in dogs is Staphylococcus spp. (aureus [68% of infections] or epidermidis [27% of infections]). A variety of other organisms, including Corynebacterium spp. and gram-negative rods, make up the remaining infections. Most of the infecting organisms are considered normal ocular flora. 11 Bacterial infection complicating keratoconjunctivitis sicca generally is caused by Staphylococcus spp. (32% to 69% of dogs) and Streptococcus spp. (9% to 25%); Pseudomonas spp. (5% to 18% of infections) is the most common gram-negative isolate. In cats Mycoplasma felis and gatea are the more common isolates associated with conjunctivitis; however, they also are commonly isolated in normal cats, calling into question the role of the organism in disease. Chlamydia (Chlamydophila felis)12 may be a concurrent pathogen, although both it and Mycoplasma spp. may reflect infection secondary to primary feline herpesvirus infection.
Why are infections of the CNS so problematic?
Infections of the CNS are uniquely problematic for three reasons: cellular components reflect functional specialization, a major portion of the CNS is sequestered from the rest of the body by physiologic barriers, and tissues of the CNS are closely confined within rigid skeletal structures such that swelling cannot occur without subsequent and potentially lethal damage. Cellular specialization is of diagnostic benefit in the identification and localization of infections of the CNS because clinical signs are often referred to a specific region of the brain.
Can antimicrobials cause seizures?
Seizures are the most likely manifestation. The antimicrobial most likely to cause seizures include selected beta-lactams (see Chapters 6 and 7 ), most notably imipenem (but not meropenem), metronidazole, and fluoroquinolones, particularly in patients also receiving nonsteroidal antiinflammatories. In general, seizures that develop as a result of drug therapy should be treated as with any acute seizural manifestation, with diazepam the preferred anticonvulsant of choice.
