Nucleoside analogs

Nucleoside analog reverse transcriptase inhibitors have formed the backbone of anti-human immunodeficiency virus therapy for the last decade (see Table Characteristics of Nucleoside Reverse Transcriptase Inhibitors). Reverse transcription is necessary for human immunodeficiency virus RNA to be used as a template to produce viral DNA, which can be integrated into the cellular genome. In order for reverse transcription to take place, deoxynucleotide must be added to the end of the elongating DNA. A 3′-hydroxyl group is present on the sugar moiety of deoxynucleotides that can form a 3′,5′-phosphodiester bond allowing further addition of nucleotide triphosphates. Several deoxynucleotide analogs have …

The characteristic lesion is a vegetation (a mass comprised of fibrin, platelets, microorganisms and their product or products on a valve leaflet). Multiple valves may be involved, as may any part of the endothelium of the heart. The incidence of endocarditis ranges from 17 to 39 cases per million person-years. There have been major changes in the epidemiology of endocarditis. The age of patients affected has …

Management of Malaria

ContentsEpidemiologyMalaria life cycleMalarial parasite development in the anopheles mosquitoLife cycle in humansBuy Most Popular Antibiotic, Antifungal, Antiparasitic, Antiviral Drugs Online no RX & OTCMalaria is a protozoan (genus Plasmodium) infection transmitted by the bite of an infected female Anopheles mosquito and rarely via a contaminated blood transfusion. It is extremely common, affecting more than 500 million persons and resulting in more than 1 million deaths each year. There are four species of the genus Plasmodium that cause malaria in man. These are P. falciparum, P. vivax, P. ovale, and P. malariae. From a clinical standpoint one must be able to distinguish between P. falciparum and non falciparum (all the others) malaria. …

Erythrocytic asexual phase

This begins with penetration into red blood cells by merozoites arising from the exoerythrocytic schizonts in the liver cells. The parasites grow rapidly, and a large central vacuole forms in the cytoplasm leading to the so-called ring form. The cytoplasm then becomes amoeboid to form the single-nucleated trophozoite. At this stage it feeds on the host cell by the process of phagotrophy during which nutrients from the red blood cell are incorporated into the parasite cytoplasm inside food vacuoles lined by a double membrane. As the hemoglobin of the RBC is metabolized the contents of …

Evaluation of the efficacy of vaccines

ContentsEradicationAdverse effects of vaccinesPRINCIPLESPoliomyelitis: A disease illustrating the principles of immunotherapyRecent additions to vaccination recommendationsImmunization of immunosuppressed hostImmunization for the travelerVaccines under developmentBuy Most Popular Antibiotic, Antifungal, Antiparasitic, Antiviral Drugs Online no RX & OTCAdequate response to immunization is most frequently judged by measuring the development of specific serum immunoglobulins (e.g., antibodies) following a course of administration of vaccine. The concentration of specific immunoglobulin in plasma is usually proportional to the degree of protection from the viral agent. However, the relation between immunologic response to a vaccine and protection afforded by it to subsequent disease must be documented in field trials. The longevity of the protective response must always be determined …

Penicillins

The latter two are “long-acting” forms. Penicillin G is useful in the treatment of streptococcal infections due to S. pyogenes (group A), S. agalactiae (group B), S. pneumoniae, viridans streptococci, Corynebacterium diphtheria, N. meningitidis, many strains of N. gonorrhea, Treponema pallidum, and many anaerobic streptococci, such as peptococcus and peptostreptococcus. In combination with aminoglycosides, any penicillin G compounds can be used to treat enterococci and L. monocytogenes infections. These organisms cause …

Aminoglycosides – antibiotic agents

ContentsBuy Most Popular Antibiotic, Antifungal, Antiparasitic, Antiviral Drugs Online no RX & OTCAminoglycosides are very potent bactericidal antibiotic agents that are active against susceptible aerobic microorganisms. They kill by inhibiting protein synthesis and to some extent by lysing the cell envelope. All the aminoglycosides (streptomycin, kanamycin, neomycin, gentamicin, amikacin, tobramycin, sisomicin, and netilmicin) share common structural features. Streptomycin is used once a day in combination with other antibiotics to treat mycobacterial infections. Neomycin is used topically to treat superficial infections (a use to be discouraged) and is also given orally preoperatively for chemoprophylaxis before large-bowel surgery. The other agents are used parenterally to treat systemic bacterial septicemia (e.g., bacterial endocarditis, or …

Chloromycetin 250mg Tablets (Chloramphenicol)

ContentsBuy Most Popular Antibiotic, Antifungal, Antiparasitic, Antiviral Drugs Online no RX & OTCVancomycin and teicoplanin are the only members of this class of antibiotics. Vancomycin is a high-molecular-weight glycopeptide that is bactericidal for gram-positive microorganisms. It inhibits cell-wall synthesis. Given parenterally, it is the drug of choice for methicillin-resistant staphylococcal infections. It should be used as an alternative for methicillin-sensitive staphylococci if the patient is allergic to penicillin. Vancomycin is also active against strains of penicillin-resistant S. pneumoniae, Leuconostoc spp., and Pediococcus spp. Some strains of Lactobacillus, Staphylococcus haemolyticus, and enterococci are resistant to vancomycin. Based on considerable clinical experience, there is a lack of clinical evidence to use combinations of …

Macrolides: Erythromycin, Clarithromycin, Azithromycin

ContentsBuy Most Popular Antibiotic, Antifungal, Antiparasitic, Antiviral Drugs Online no RX & OTCErythromycin is a macrolide antibiotic that binds to the 50-S subunit of the ribosomes. It kills susceptible bacteria by interfering with their protein synthesis. Erythromycin is active against many aerobic gram-positive bacteria, selected gram-negative bacteria (including species of Legionella, N. meningitidis, H. influenzae, and Bordetella pertussis), and nonbacterial species (e.g., C. trachomatis, mycoplasma, and certain rickettsial species). There are three available oral preparations of erythromycin: erythromycin stearate, erythromycin ethylsuccinate, and erythromycin estolate. The first two preparations do not have intrinsic antibacterial activity until they dissociate or hydrolyze (respectively) to active compounds. They are routinely recommended to be taken orally …
