Mycobacterium ulcerans, the etiological agent of Buruli ulcers, is an environmental pathogen. We cultivated it in an amphibian (XTC-2) cell line that grows at 28 degrees C. By counting of Ziehl-Neelsen-stained mycobacteria and by quantitative PCR analysis, we found that M. ulcerans multiplies rapidly in association with XTC-2 cells. Transmission electron microscopy demonstrated the presence of ...

A 42-year-old male presented in June of 2011 with nocturnal fevers, night sweats, an 8-kg weight loss, and a cutaneous right chest wall mass. In March of 2013, a computed tomographic scan of the thorax showed a 54 × 18 × 26-mm right lower lobe mass with peripheral calcifications, and in May of 2013, he was admitted for a segmental lobectomy, in which histologic examination of the pulmonary tiss...

We report a case of mycobacterial infection at the sites of previous injections of botulinum toxin A in a 45-year-old woman. She presented with erythematous, swollen, warm, and tender plaques and nodules at the points of injection from which a biopsy was taken, demonstrating a deep dermal and hypodermal abscessified epithelioid granulomatous inflammatory infiltrate in which some acid-fast bacil...

A 68-year-old man on peritoneal dialysis (PD) was hospitalized with the clinical picture of peritonitis. The patient was diagnosed with peritonitis caused by nontuberculous mycobacteria (NTM) according to positive Ziehl-Neelsen staining and negative Mycobacterium tuberculosis polymerase chain reaction results. Oral levofloxacin and clarithromycin, and later intraperitoneal imipenem were started...

The prevalence of Cryptosporidium infection among lambs and goat kids in Serbia was examined. The animals were grouped according to age, i.e., up to 30 days and from 31 to 90 days. The infection was diagnosed using three coprological procedures. Sheather’s sugar flotation was employed to determine the concentration of oocysts. Modified Ziehl-Neelsen technique and modified Kinyoun technique were...

The presence of galectin-3 was immunohistochemically quantified in bovine intestines infected with paratuberculosis (Johne's disease) to determine whether galectin-3 was involved in the formation of granulation tissue associated with the disease. Mycobacterium avium subsp. paratuberculosis infection was histochemically confirmed using Ziehl-Neelsen staining and molecularly diagnosed through rpo...

Tuberculosis is one of the most common causes for cervical lymphadenopathy apart from distant metastasis and lymphoma. Early diagnosis this disease reduces patient’s morbidity by initiating early course Antitubercular treatment with complete resolution disease. Hence, condition we are searching a modality which can give results in shorter period time, more sensitive, specific important easier t...
