Paratuberculosis (John's disease) is infectious and chronically progressive granulomatous disease which affects domestic and wild ruminants. The causative agent is Mycobacterium avium paratuberculosis (MAP), a slow growing mycobactin dependent acid-fast bacillus. We investigated the detection and frequency of MAP in apparently healthy dromedary and Bactrian camels by insertion sequence 900 (IS9...

in recent years, tuberculosis has had a significant rise, caused mainly by the epidemic of acquired immunodeficiency syndrome. the anorectal tuberculosis is a very rare presentation. herein, we presented a 67-year-old man who has had renal transplantation and presented with hematochezia and painful defecation since 6 months before. biopsy was taken from the lower rectal ulcerated lesion. histop...

background chronic rhinosinusitis is an inflammatory-infectious disease involved paranasal sinuses as a common site of microbial pathogens and infections in patients suffering from the disease. the disease is labeled chronic when it lasts for more than 12 weeks. objectives as these infections constitute an important cause of morbidity it can be a strong life-threatening factor, in this investig...

BACKGROUND Tuberculosis (TB) remains as one of the most serious infectious diseases in the world. Pulmonary tuberculosis can occur with other pulmonary diseases caused by opportunistic organisms such as Nocardia spp. particularly in immunocompromised patients. Therefore, diagnosis of co-infection at the early stage of the disease could be lifesaving. OBJECTIVES The goal of this study was to d...

This report describes two cases of mycobacterial infection with pseudo-Gaucher cells. Both patients had no clinical evidence of inherited Gaucher disease. The first case was a patient with AIDS and Mycobacterium avium intracellulare involving the lung, spleen, and bone marrow. The bone marrow aspirates showed many histiocytes with needle-like inclusions. Acid fast staining showed that these his...

Modified Ziehl–Neelsen staining for Mycobacterium leprae is a time-tested technique in the evaluation of leprosy. The helps to classify clinical types leprosy into those with low and high bacillary load. It also useful assessing response therapy, identifying defaulters, differentiating relapse from late reversal reactions. In this net educational video, we demonstrate taking an ear lobe smear p...

BACKGROUND Tuberculosis (TB) is an increasing public health concern worldwide. On a global scale it has a devastating impact in developing nations. Genital TB, an extrapulmonary form, is not uncommon particularly in areas where pulmonary TB is prevalent. Genital TB may be asymptomatic or may even masquerade as other gynaecological conditions; hence, diagnosis requires a high degree of suspicion...

Three hundred stool samples for routine ova and parasite examination were examined as saline and iodine wet preparations, the results were then compared with the Zeihl-Neelsen-modified Acid Fast staining (MAFS), as the oocysts are acid fast in character. Examination with saline preparation was unable to detect any oocyst, while iodine preparation yielded three oocyst and stained smears with MAF...
