TRACHOMA By Anna Melton http://go-near.org/?p=172
Trachoma is the world’s leading cause of preventable blindness
Trachoma is a contagious bacterial infection in the eye which causes blindness after multiple reinfections.
Trachomatous inflammation-follicular http://www.who.int/blindness/causes/trachoma_documents/en/index.html
The bacteria infects the conjunctival covering which leads to irritation and inflammation.

Trachomatous inflammation-follicular and intense http://www.who.int/blindness/causes/trachoma_documents/en/index.html
Trachomatous scarring http://www.who.int/blindness/causes/trachoma_documents/en/index.html
Eventually, the eyelid will turn inward causing the eyelashes to scar the cornea.
Trachomatoustrichiasis http://www.who.int/blindness/causes/trachoma_documents/en/index.html
Trachoma is caused by the bacterium Chlamydia trachomatis http://www.microbelibrary.org/library/gram-stain/3089-examination-of-gram-stains-of-cervical-and-urethral-discharges
1.Elementary body (EB) attaches to surface of cell. 2. Elementary body enters by endocytosis. 3. Elementary body enters endosome. 4. Elementary bodies reorganize into reticulate bodies (RB). http://pathmicro.med.sc.edu/mayer/chlamyd.htm
5. Reticulate bodies (RB) replicate. 6. Reticulate bodies (RB) reorganize into Elementary bodies (EB) 7. Both RB and EB reside in inclusion granule. 8. Reverse endocytosis http://pathmicro.med.sc.edu/mayer/chlamyd.htm

Chlamydia trachomatisis spread through direct contact with an infected person. http://anglicansablaze.blogspot.com/
Flies also play a major role in the spread of the disease. http://bjo.bmj.com/content/88/6/750.full
Poor sanitation, dirty water, and lack of hygiene are causes of trachoma. http://sitemaker.umich.edu/aqua/home
Thus trachoma primarily affects developing countries in Africa and Asia. https://apps.who.int/pbd/trachoma/MAPS.htm
Trachoma binds a family to the cycle of poverty. Mother Father Child daughter must drop out of school to take care of family Will likely develop blinding trachoma as an adult Unable to work increasing financial troubles
Trachoma affects the eye in five stages that can be diagnosed through an eye examination. http://www.guardian.co.uk/global-development/2011/jan/06/prevent-blindness-trachoma-poor-countries-2020
http://www.who.int/blindness/causes/trachoma_documents/en/index.htmlhttp://www.who.int/blindness/causes/trachoma_documents/en/index.html
The early stages are easily treated by one dose of Zithromax or bytopical application of Achromycin. http://allpills.biz/order-zithromax-online-en.html VS http://www.sightsavers.org/blogs/insights/archana_patel/16594.html
Zithromax inhibits protein synthesis by disrupting mRNA translation http://pharmacologycorner.com/protein-synthesis-inhibitors-macrolides-mechanism-of-action-animation-classification-of-agents/
Once the disease progresses to Trichiasis, surgery is necessary. http://www.who.int/blindness/causes/trachoma_documents/en/index.html
The SAFE strategy was developed by WHO as an approach to treatment and prevention of trachoma.
Surgery http://www.cbmuk.org.uk/our-work/campaign/nicodems-story-NTDs-trachoma
Antibiotics www.sightsavers.org/images/content/17857
Facial Cleanliness http://fieldnotes.unicefusa.org/2011/06/effort_to_eliminate_trachoma.html
Environmental Improvement http://fiaintl.org/fiaintl/myweb.php?hls=10021&id=7
WHO launched Global Elimination of Trachoma 2020 (GET). http://new.paho.org/hq/index.php?option=com_content&view=article&id=6668%3Aq16th-meeting-of-the-who-alliance-for-the-global-elimination-of-blinding-trachoma-get-by-2020q&catid=4451%3Ahsd0108m-neglected-d-trachoma-meeting-&lang=en trachoma.org/global-strategy-2020-INSight
Although surgery to reverse the effects of trichiasis is free or low cost in developing countries, the number of cases operated has grown less than anticipated.
Saul N. Rajak, et al. asked “Why Do People Not Attend for Treatment for Trachomatous Trichiasis in Ethiopia? A Study of Barriers to Surgery”
The Top 5 List Lack of Time Financial Constraints No-one to accompany No symptoms Fear of surgery
They concluded “that a locally delivered outreach campaign providingfree or low-cost surgery would overcome or reduce the three most common barriers…” http://www.sightsavers.org/about_us/default.html http://www.sightsavers.org/our_work/how_we_help/health/causes_of_blindness/trachoma/16916.html
