Background: Ziehl-Neelsen (ZN) method proves to be a good modality of microscopic detection of Acid Fast Bacilli (AFB) in Fine Needle Aspiration (FNA) smears of lymph nodes though has a low sensitivity. It has a potential to become an even more valuable tool if its sensitivity could be increased. Objective: To improve microscopic detection of AFB in FNA cytology of lymph nodes using modified bl...

Background and Objective: Tuberculosis is still a major health problem, involving about 1/3 of the world ́s population. Diagnosis is difficult when we only use Ziehl-Neelson staining. Many cases may be missed. A more rapid and sensitive diagnostic method is necessary. PCR may be helpful. The aim of this study is to compare PCR, Zieh-Neelsen staining and histopathologic findings in diagnosis of t...

This study describes aspects of the infection caused by the myxosporean genus Henneguya, which forms cysts in the bony portion of the gill filaments of Hypophthalmusmarginatus. Specimens of this catfish were acquired dead from artisanal fishermen near the town of Cametá, state of Pará, northern Brazil, between July 2011 and May 2012. They were transported in refrigerated containers to the Carlo...

Purpose. The histological diagnosis of Mycobacterium tuberculosis (MTB) remains a diagnostic challenge despite different methods. Immunohistochemistry (IHC) not only could confirm granulomatous tissue involvement but also can demonstrate MTB antigen immunolocalization. This study tries to clarify the details of immunohistochemical staining for MTB with pAbBCG. Materials/Methods. Twenty-three co...

INTRODUCTION The present study aimed to establish the frequency and clinical characteristics of cutaneous tuberculosis among Mexican adult patients. METHODOLOGY Ninety-five patients with clinically compatible lesions to cutaneous tuberculosis participated in the study. All patients were HIV negative and none of them had previous anti-TB treatment. A skin biopsy was taken from every patient su...

BACKGROUND To report a rare presentation of culture-positive Mycobacterium chelonae corneal ulcer and its management. FINDINGS We report a rare case of a patient with a history of chronic pain and blurriness of vision. Examination revealed a chronic nonhealing paracentral corneal ulcer inferiorly at the 5-7 o'clock meridian with anterior chamber reaction unresponsive to routine antibiotic and...
