Background: BCG vaccination which is administered to prevent tuberculosis is sometimes associated with serious complications. This study aimed to determine the incidence of complications of BCG vaccination in Babol. Methods: All infants who received BCG vaccination between 2011-2013 in health centers of Babol entered the study. Data regarding complications of vaccine were extracted according...

BACKGROUND Fine needle aspiration biopsy has become a standard approach for diagnosis of peripheral tuberculous lymphadenitis. The aim of this study was to compare the performance of Xpert MTB/RIF and Ustar EasyNAT TB IAD nucleic acid amplification assays, against acid-fast bacilli microscopy, cytology and mycobacterial culture for the diagnosis of TB lymphadenitis in children from a TB-endemic...

BACKGROUND Bacille Calmette-Guérin (BCG) vaccine is one of the most widely used vaccines globally. Management of local BCG complications (injection site reactions and suppurative or non-suppurative lymphadenitis) varies between clinicians, and the optimal approach remains uncertain. AIM To determine the clinical features, management and outcome of BCG complications at two large acute hospital...

The purpose of this study was to describe the clinicopathological features of 40 cases of necrotizing non-granulomatous lymphadenitis in Thai patients. The clinical features, histomorphology and special stains were evaluated in 40 Thai patients from the pathology records of King Chulalongkorn Memorial Hospital from January 2001 to December 2003 in those diagnosed as having necrotizing non-granu...

OBJECTIVE To evaluate the incidence, treatment and clinical outcomes of tuberculous (TB) lymphadenitis at Penang General Hospital, Malaysia. MATERIALS AND METHODS Penang General Hospital is the referral center for all tuberculosis patients in the state of Penang. Patient records were reviewed to identify patients with confirmed diagnosis of TB lymphadenitis between January 2006 and December 2...

The role of anti-leishmanial immune response underlying the susceptibility/resistance during canine visceral leishmaniasis (CVL) has been recognized throughout ex vivo and in vitro investigations. Recently, we demonstrated that immunoglobulin levels (Igs), as well as the parasite load are relevant hallmarks of distinct clinical status of CVL. To further characterize and upgrade the background o...

Visceral leishmaniasis is a severe form of the disease, caused by Leishmania infantum in the New World. Patients present an anergic immune response that favors parasite establishment and spreading through tissues like bone marrow and liver. On the other hand, Leishmania braziliensis causes localized cutaneous lesions, which can be self-healing in some individuals. Interactions between host and ...

BACKGROUND: In yeast and Caenorhabditis elegans, Silent Information Regulator (SIR2) proteins have been shown to be involved in ageing regulation. In Leishmania, the LmSIR2rp was originally isolated from the excreted/secreted material of the Leishmania parasites. Among the function(s) of this protein in Leishmania biology, we have documented its implication in parasite survival, and in particul...

Seven rhesus macaques were infected intradermally with 10(7) promastigotes of Leishmania (Leishmania) major. All monkeys developed a localized, ulcerative, self-healing nodular skin lesion at the site of inoculation of the parasite. Non-specific chronic inflammation and/or tuberculoid-type granulomatous reaction were the main histopathological manifestations of the disease. Serum Leishmania-spe...

Casein kinase 1 (CK1) plays an important role in eukaryotic signaling pathways, and their substrates include key regulatory proteins involved in cell differentiation, proliferation and chromosome segregation. The Leishmania genome encodes six potential CK1 isoforms, of which five have orthologs in other trypanosomatidae. Leishmania donovani CK1 isoform 4 (Ldck1.4, orthologous to LmjF27.1780) is...
