Occasionally, amastigotes may be seen lying free between cells. However, the retrieval of tissue samples is often painful for the patient and identification of the infected cells can be difficult. So, other indirect immunological methods of diagnosis are developed, including enzyme-linked immunosorbent assay, antigen-coated dipsticks, and direct agglutination test. Although these tests are readily available, they are not the standard diagnostic tests due to their insufficient sensitivity and specificity. Several different polymerase chain reaction (PCR) tests are available for the detection of Leishmania DNA. With this assay, a specific and sensitive diagnostic procedure is finally possible. The most sensitive PCR tests use minicircle kinetoplast DNA found in the parasite. Kinetoplast DNA contains sequences for mitochondrial proteins in its maxicircles(~25-50 per parasite), and guide RNA in its minicircles(~10000 per parasite) of the kinetoplast. With this specific method, one can still detect Leishmania even with a very low parasite load. When needing to diagnose a specific species of Leishmania, as opposed to only detection, other PCR methods have been superior.Most forms of the disease are transmitted only from nonhuman animals,  but some can be spread between humans. Infections in humans are caused by about 21 of 30 species that infect mammals; the different species look the same, but they can be differentiated by isoenzyme analysis, DNA sequence analysis, or monoclonal antibodies. Prevention
Using insect repellent to exposed skin and under the ends of sleeves and pant legs. Follow the instructions on the label of the repellent.
From the gallbladder, bile enters the intestine in individual portions. In the absence of a gallbladder, bile enters the intestine constantly, but in small quantities. Thus, it may be insufficient for the digestion of fatty foods. Postcholecystectomy syndrome treatment depends on the identified violations that led to it. Typically, the patient is recommended a dietary restriction table with fatty foods, enzyme preparations, antispasmodics, and sometimes cholagogue.If the pain is caused by biliary microlithiasis, oral ursodeoxycholic acid can alleviate the condition.A trial of bile acid sequestrant therapy is recommended for bile acid diarrhea.Functional dyspepsia is subdivided into Epigastric Distress Syndrome (EPS) and Post-Prandial Distress Syndrome (PDS). Treatment for EPS and PDS can both include proton pump inhibitors and dopamine antagonists. Tricyclic antidepressants have also been proven effective for nausea, vomiting, early satiety, impaired motility and other related symptoms.When investigation reveals no abnormalities within the abdominal cavity, the attending physician may consider Anterior cutaneous nerve entrapment syndrome (ACNES) as a possible cause. ACNES may present with pseudovisceral symptoms, including nausea, bloating, diarrhea and early satiety. References
