Histoplasmosis masquerading as tuberculosis: A report of three cases in immunocompetent children.

Indian J Pathol Microbiol 2022 Apr-Jun;65(2):406-409

Department of Pediatric Surgery, IPGMER, Kolkata, West Bengal, India.

The most common cause of granulomatous lymphadenitis in countries like ours is mycobactrium tuberculosis followed by atypical mycobacterial infection, fungal infections, parasitic infection, cat scratch disease, lymphogranuloma venereum (inguinal lymphadenopathy), and leprosy Here, we present three cases of lymphadenopathy due to histoplasmosis in immunocompetent children. Two of them presented with fever, lymphadenopathy, initially diagnosed as granulomatous lymphadenitis consistent with tuberculosis on FNAC and were put on antitubercular drugs. However, their condition gradually became worse. Read More

Clinical and Experimental Sciences, University of Southampton, Southampton, Hampshire, SO166YD, UK.

is a prolific human pathogen that can cause serious long-term conditions if left untreated. Recent developments in genetics have opened the door to conducting targeted and random mutagenesis experiments to identify gene function. In the present study, an inducible transposon mutagenesis approach was developed for using a self-replicating vector to deliver the transposon-transposase cassette - a significant step towards our ultimate aim of achieving saturation mutagenesis of the genome.

Cureus 2021 Dec 6;13(12):e20216. Epub 2021 Dec 6.

Infectious Diseases, Waterbury Hospital, Waterbury, USA.

Lymphogranuloma venereum (LGV) can present as a sexually transmitted anorectal syndrome and is caused by  serotypes L1, L2, and L3. It was rare in the western world until a recent outbreak among men who have sex with men (MSM) in Europe and North America. Limited availability of diagnostic tests differentiating LGV from non-LGV  can make the diagnosis challenging.

[Chlamydial infection still a common and sometimes serious infection].

Lakartidningen 2021 11 2;118. Epub 2021 Nov 2.

docent, klinisk mikrobiologi, Akademiska sjukhuset, Uppsala.

Chlamydial infection is the most common bacterial sexually transmitted infection in Sweden and worldwide, despite extensive testing, efficient treatment and partner notification. The incidence of Lymphogranuloma venereum, currently occurring among men who have sex with men and most often in the rectum, shows no tendency to decline. This infection is usually symptomatic but still evading diagnosis due to similarities to other causes of proctitis. Read More

Use of real-time PCR as an alternative to conventional genotyping methods for the laboratory detection of lymphogranuloma venereum (LGV).

Diagn Microbiol Infect Dis 2021 Dec 27;101(4):115532. Epub 2021 Aug 27.

Division of STD Prevention, National Center for HIV, Hepatitis, STD, TB Prevention, Centers for Disease Control and Prevention, Atlanta, GA, USA.

Lymphogranuloma venereum (LGV) can be differentiated from non-LGV chlamydial infection using Sanger sequencing or molecular assays, including those that are commercially-available internationally. Here, we describe the performance of a rapid real-time PCR (RT-PCR)-based strategy in differentiating Chlamydia trachomatis infections associated with LGV or non-LGV serovars. One hundred three rectal swabs, previously genotyped using Sanger sequencing of the ompA gene as a reference method, were tested in the RT-PCR assays. Read More

Microb Genom 2021 06;7(6)

Clinical Bacteriology & Mycology, University Hospital Basel, University of Basel, Switzerland.

Lymphogranuloma venereum (LGV), the invasive infection of the sexually transmissible infection (STI) , is caused by strains from the LGV biovar, most commonly represented by -genotypes L2b and L2. We investigated the diversity in LGV samples across an international collection over seven years using typing and genome sequencing. LGV-positive samples (=321) from eight countries collected between 2011 and 2017 (Spain =97, Netherlands =67, Switzerland =64, Australia =53, Sweden =37, Hungary =31, Czechia =30, Slovenia =10) were genotyped for and variants.
