Resistomycin is an antibiotic with the molecular formula C22H16O6. [3] [1] [4] Resistomycin is similar to hypericin. [5] Resistomycin was first isolated in 1951 from the bacterium Streptomyces resistomycificus . [6]
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit growth of viruses are termed antiviral drugs or antivirals rather than antibiotics. They are also not effective against fungi; drugs which inhibit growth of fungi are called antifungal drugs.
Sinusitis, also known as rhinosinusitis, is inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include thick nasal mucus, a plugged nose, and facial pain. Other signs and symptoms may include fever, headaches, a poor sense of smell, sore throat, a feeling that phlegm is oozing out from the back of the nose to the throat along with a necessity to clear the throat frequently and frequent attacks of cough.
A urinary tract infection (UTI) is an infection that affects part of the urinary tract. When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis). Symptoms from a lower urinary tract infection include pain with urination, frequent urination, and feeling the need to urinate despite having an empty bladder. Symptoms of a kidney infection include fever and flank pain usually in addition to the symptoms of a lower UTI. Rarely the urine may appear bloody. In the very old and the very young, symptoms may be vague or non-specific.
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable.
Acne, also known as acne vulgaris, is a long-term skin condition that occurs when dead skin cells and oil from the skin clog hair follicles. Typical features of the condition include blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to lack of confidence, anxiety, reduced self-esteem, and, in extreme cases, depression or thoughts of suicide.
Pharyngitis is inflammation of the back of the throat, known as the pharynx. It typically results in a sore throat and fever. Other symptoms may include a runny nose, cough, headache, difficulty swallowing, swollen lymph nodes, and a hoarse voice. Symptoms usually last 3–5 days, but can be longer depending on cause. Complications can include sinusitis and acute otitis media. Pharyngitis is a type of upper respiratory tract infection.
Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum. Hypericin is believed to act as an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.
Postpartum infections, also known as childbed fever and puerperal fever, are any bacterial infections of the female reproductive tract following childbirth or miscarriage. Signs and symptoms usually include a fever greater than 38.0 °C (100.4 °F), chills, lower abdominal pain, and possibly bad-smelling vaginal discharge. It usually occurs after the first 24 hours and within the first ten days following delivery.
Demeclocycline is a tetracycline antibiotic which was derived from a mutant strain of Streptomyces aureofaciens.
Endometritis is inflammation of the inner lining of the uterus (endometrium). Symptoms may include fever, lower abdominal pain, and abnormal vaginal bleeding or discharge. It is the most common cause of infection after childbirth. It is also part of spectrum of diseases that make up pelvic inflammatory disease.
Streptomyces spectabilis is a bacterium species from the genus of Streptomyces. Streptomyces spectabilis produces hangtaimycin, gentamicin, kanamycin, neomycin B, sisomycin, tobramycin, paromomycin, spectinabilin, spectinomycin, aminocyclitol, actinospectacin, prodigiosine and the streptovaricin complex.
The following list of publications by Richard Dawkins is a chronological list of papers, articles, essays and books published by British ethologist and evolutionary biologist Richard Dawkins.
Penicillium citrinum is an anamorph, mesophilic fungus species of the genus of Penicillium which produces tanzawaic acid A-D, ACC, Mevastatin, Quinocitrinine A, Quinocitrinine B, and nephrotoxic citrinin. Penicillium citrinum is often found on moldy citrus fruits and occasionally it occurs in tropical spices and cereals. This Penicillium species also causes mortality for the mosquito Culex quinquefasciatus. Because of its mesophilic character, Penicillium citrinum occurs worldwide. The first statin (Mevastatin) was 1970 isolated from this species.
Streptomyces aurantiacus is a bacterium species from the genus Streptomyces which produces aurantin, pamamycin-621, aurantimycin A, aurantimycin B, aurantimycin C, aurantimycin D, dihydronancimycin and ancimycin.
Streptomyces coeruleorubidus is a bacterium species from the genus of Streptomyces which has been isolated from marine sediment. Streptomyces coeruleorubidus produces the following medications: pacidamycin 1, baumycin B1, baumycin B2, baumycin C1, feudomycin A, feudomycin B, feudomycin C, ficellomycin, feudomycinone A, and rubomycin.
Streptomyces diastatochromogenes is a bacterium species from the genus of Streptomyces. Streptomyces diastatochromogenes produces polyketomycin, concanamycin A, concanamycin B, concanamycin C, momofulvenone A, azdimycin, toyocamycin and oligomycins.
Streptomyces nitrosporeus is a bacterium species from the genus of Streptomyces which has been isolated from garden soil in Japan. Streptomyces nitrosporeus produces Benzastatin E, Benzastatin F, Benzastatin G Nitrosporeusine A and Nitrosporeusine B and the antibiotics nitrosporin and virantomycin and the inhibitor of angiotensin-converting enzyme foroxymithine. Streptomyces nitrosporeus can degrade cellulose.
Aureothin is a natural product of a cytotoxic shikimate-polyketide antibiotic with the molecular formula C22H23NO6. Aureothin is produced by the bacterium Streptomyces thioluteus that illustrates antitumor, antifungal, and insecticidal activities and the new aureothin derivatives can be antifungal and antiproliferative. In addition, aureothin, a nitro compound from Streptomyces thioluteus, was indicated to have pesticidal activity against the bean weevil by interfering with mitochondrial respiratory complex II.
John Charles Sherris was an English-American medical doctor, pathologist, and bacteriologist. He was the president of the American Society for Microbiology (ASM) in 1983.
