Ofparticular note is the increase in mobilethe genes for resistance traits can be transferred among strains bearing metallo--lactamases that inactivate carbapenems bacteria of different taxonomic and ecological groups by means of drugs that are often the last resort in serious infections of Gram-neg- mobile genetic elements such as bacteriophages, plasmids, naked ative bacteria31,32. And, like the antibiotics themselves, resistance recently recommended fluoroquinolones.

In addition, as discussed above, altering the use of that antimicrobial in that environment. Some transposons contain integronsmore complex transposons that contain a site for integrating different antibiotic resistance genes and other gene cassettes in tandem for expression from a single promoter91. Originally discovered among Gram-negative bacteria, integrons have been since located in Gram-positive commensal floraa newly found reservoir of these unique genetic elements92. A model of resistance gene spread is the tet(M) tetracycline resistance gene, which is commonly located on the transposon Bacteriophage Tn916 (ref. It has been found in Gram-positive and Gram- Transposon negative bacteria, aerobic and anaerobic bacteria, and in all Plasmid environmental and biological niches94. The pneumococci have shown that the chromosomal location of the resistance determinant is not a safeguard against its spread. Bacteria themselves are mobile and can easily travel from person to person and between countries. Resistant pneumococci in Iceland and in the United States have been shown to be the progeny of strains that initially appeared in Spain85. Thus, countries and Chromosome citizens worldwide have become part of a global microbial ecology, tn tn sharing and spreading the consequences of antimicrobial resistance. Some are directed at the antibiotic itself: enzymes such as -lactamases destroy penicillins and cephalosporins, and modifying enzymes inactivate chloramphenicol Antibiotic-resistance Antibiotic- and aminoglycosides such as streptomycin and gentamicin. For example, the -lactamases now number in the hundreds and more than 20 different resistance determinants mediate an efflux of tetracyclines100. In addition, more than one type of mechanism may provide resistance to the same antibiotic; for Chromosome Antibiotic- example, tetracycline resistance can be effected by either efflux or altering Antibiotic ribosome protection101. Although most fluoroquinolone resistance enzyme stems from chromosomal mutations in the gyrase target or from drug efflux, a plasmid-mediated resistance to fluoroquinolones has been recently described102. Multidrug resistance can be specified by chromosomal genes for regulatory proteins such as MarA and SoxS. These proteins promote drug resistance by controlling the expression of other chromosomal genes, Bacterial cell such as those involved in drug efflux61. Ecologically speaking, it is the density of antibiotic usage that Some studies have, however, tracked a decline in resistance frequen- enhances resistance selection and its effects.

Nonetheless, resistance generally becomes a factory of resistant bacteria that enter the environment.
Vaginitis: bacterial vaginosis hiv transmission route statistics purchase aciclovir line, vaginal candidiasis and /or trichomoniasis are the usual causes of vaginitis hiv infection probability purchase 800mg aciclovir free shipping.

Cervicitis: The presence of purulent exudates from the cervical os indicates infection with N. In general, Gram stains are not helpful in diagnosing gonorrhea in females (low sensitivity).

Genital Ulcer: A genital ulcer is a loss of continuity of the skin of the genitalia. Genital ulcers may be painful or painless and are frequently accompanied by inguinal lymphadenopatly. Common Etiology agents: Treponema pallidum (syphilis) Haemophilus ducreyi (chancroid) Calymmatobacterium granulomatis (granuloma inguinale) C. Little information about its prevalence in Ethiopia Clinical Manifestation Incubation period usually1 to 4 weeks may be as long as a year The patient usually presents with a non suppurative genital lesion which develops from a small firm papule to painless ulcer with a beefy-red appearance and non-purulent base Lesion bleeds easily, expand gradually Extra inguinal in 6% of cases 50% women have lesion on cervix Complications o Genital pseudo-elephantiasis of labia o Adhesion o Urethral, vaginal or rectal stenosis Management of Genital Ulcer 1. When specific Etiologic diagnosis is not made Syndromic approach Recommended treatment for non-vesicular genital ulcer Benzanthine penicillin 2. The presence of pus cells in numbers exceeding those of epithelial cells suggests infection of the lower genital tract. The spectrum of activity of the antimicrobial agents should cover the following organisms: N. Inguinal bubo: Inguinal bubo is an enlargement of the lymph glands in the groin area. Non-sexually transmitted local or systemic infections can also cause inguinal lymphadenopathy. Clinical feature: Usually patients complain of unilateral or bilateral painful swelling in the groin, but buboes can be painless. Scrotal Swelling Syndrome The cause of scrotal swelling depend on the age of the patient For those younger than 35 years N. Tetanus Learning Objective: At the end of this unit the student will be able to 1. Design appropriate methods of prevention for tetanus Definitions Tetanus is a neurologic disease characterized by increased muscle tone and spasms caused by toxin released from the bacteria Clostridium tetani. They are also resistant to different disinfectant and even to boiling for less than 20 minutes. Epidemiology Tetanus occurs sporadically and almost always affects non-immunized persons. Partially immunized persons or fully immunized individuals who fail to maintain adequate immunity are also affected. It also occurs more frequently in warmer climates, during summer months and in males. Neonates and young children are affected more in developing countries where immunization programs are not comprehensive. Most cases of tetanus follow injuries especially during farming, gardening or other outdoor activities. Tetanospasmin may also block neurotransmitter release at the neuromuscular junction and produce weakness or paralysis. Generalized tetanus occurs when toxin enters into blood stream and lymphatic to affect distant nerve endings. Clinical Manifestations The incubation period (time between the injury and first symptom) of tetanus is about 7 10 days but it may range from 1 day to 2 months. The shorter the incubation period and period of onset, the more severe the disease becomes. There are different forms of tetanus: neonatal, generalized and localized tetanus. Generalized Tetanus The median time of onset after injury is seven days; but could occur as early as with in three days.
