Burkholderia vietnamiensis causing a non-lactational breast abscess in a non-cystic fibrosis patient in Tamil Nadu, India
We present here a report of a case of Burkholderia vietnamiensis causing a non-lactational breast abscess in a non-CF patient. The pathogen was identified as B. cepacia using Vitek system and matrix-assisted laser desorption ionisation–time of flight. This was confirmed by polymerase chain reaction (PCR) using recA genus-specific gene and sequencing of the PCR amplicons. recA-restriction fragment length polymorphism and recA gene sequencing revealed that the isolate is B. vietnamiensis. This is the first description of B. vietnamiensis isolated from a clinical case from India. (Source: Indian Journal of Medical Microbiology)

First report of Vibrio cholerae O9, novel st520, isolated from a child with bacteraemia-associated sepsis
We describe a case of sepsis in a child with spinal dysraphism caused by a V. cholerae O9 strain belonging to a novel sequence type (ST520). The present case highlights the need of considering V. cholerae non-O1/O139 as one of the pathogens while dealing with sepsis cases, and also, the study expounds the importance of proper characterisation of the pathogen for an effective treatment.

Adrenal histoplasmosis in immunocompetent individuals a case series from the North-Western part of India, Rajasthan province: An emerging endemic focus
We describe five immunocompetent men with adrenal histoplasmosis presenting with constitutional symptoms. Four patients had bilateral adrenal involvement, whereas one had unilateral adrenal mass. Three patients had adrenal insufficiency at presentation and the other two developed adrenal insufficiencies during follow-up. All the patients received amphotericin B and itraconazole treatment which led to symptomatic improvement but adrenal insufficiency persisted in all patients at the end of the follow-up.

Streptococcus dysgalactiae septic arthritis of sternoclavicular joint with bacteraemia
Pruthu Narendra Dhekane, Ram Gopalakrishnan, V Lakshmi Sree, V Dedeepiya DevaprasadIndian Journal of Medical Microbiology 2020 38(3):481-484 Invasive infections due to Streptococcus dysgalactiae are uncommon in the adult population, and sternoclavicular joint septic arthritis (SCSA) is usually caused by other organisms such as Staphylococcus aureus and Pseudomonas aeruginosa. We hereby report a case of SCSA caused by this organism. The patient responded well to intravenous antibiotics and recovered fully without any surgical intervention.

An unexpected host in a soft-tissue lesion of thigh
We describe the case of a 35-year-old female patient who presented with a slow-growing soft-tissue swelling with ulceration over the thigh. On clinical and radiological examination, a provisional diagnosis of soft-tissue neoplasm was made. After resection, histopathological sections showed a closely packed cyst with innumerable endospores. The present case report documents the rare occurrence of an incidentally detected cutaneous rhinosporidiosis causing diagnostic difficulty. (Source: Indian Journal of Medical Microbiology)

A rare case of Colletotrichum truncatum keratitis in a young boy with complete healing after medical treatment
Josephine S Christy, A Balraj, Aditi AgarwalIndian Journal of Medical Microbiology 2020 38(3):475-477 Colletotrichum is a rare fungal pathogen, which is known to cause anthracnose in plants and keratitis or subcutaneous infections in humans. Among the seven Colletotrichum species reported in eye infections, truncatum species is usually virulent with poor visual prognosis even after surgical treatment. Here we report a case of Colletotrichum truncatum keratitis in a young boy with thorn injury that completely resolved with topical natamycin and voriconazole.

Mycotic keratitis due to Cylindrocarpon lichenicola: Successful salvage of the eye
M Suchitra Shenoy, Rajesh R Nayak, Vijay Pai, K Archana BhatIndian Journal of Medical Microbiology 2020 38(3):472-474 We hereby report a successfully salvaged eye due to mycotic keratitis by Cylindrocarpon lichenicola in a 60-year-old female from Kasaragod (Kerala). The patient came with a history of pain, photophobia and decreased vision of the right eye. The microbiological investigations of the corneal scraping revealed C. lichenicola. C. lichenicola is a soil saprophyte. Since the ulcer worsened paracentesis followed by therapeutic keratoplasty and adjunct therapy with natamycin drops, voriconazole drops and oral keto...

False-positive blood cultures: The need for follow-up
Suverna Kirolikar, Ambreen Pandrowala, Sangeeta Joshi, Ruchira Misra, Sujata MushrifIndian Journal of Medical Microbiology 2020 38(3):469-471 The diagnosis of blood-borne infections in immunocompromised patients is a major challenge for the clinical microbiology laboratory. Isolation of bloodborne pathogens in these patients has profound clinical implications, yet is fraught with technical problems, including the presence of unusual and difficult to isolate pathogens. Coupled with this is the problem of false-positive blood culture signals from automated blood culture systems which further delays the definitive diagnosis....

Prevalence of COVID-19 antibodies in healthcare workers at the peak of the pandemic in Mumbai, India: A preliminary study
Tanu Singhal, Sweta Shah, Reshma Naik, Amreen Kazi, Pooja ThakkarIndian Journal of Medical Microbiology 2020 38(3):461-463 Healthcare worker (HCW) infections due to COVID-19 are of serious consequence. Testing for antibodies against COVID-19 in HCWs has been previously recommended. We conducted a serosurvey in HCWs at a private hospital in Mumbai which is treating COVID patients. A total of 244 HCWs were tested. The prevalence of infection in asymptomatic HCWs was 4.3% and in previously symptomatic untested HCWs was 70%. We recommend that HCWs with a previous history of COVID symptoms who were not te...

Arterial blood gas as a prognostic indicator in patients with sepsis
Sayan Mukherjee, Suvrajyoti Das, Sudipta Mukherjee, Pralay Shankar Ghosh, Sanjay BhattacharyaIndian Journal of Medical Microbiology 2020 38(3):457-460 Abnormal arterial blood gas (ABG) among patients with sepsis is an important prognostic indicator. All-cause mortality was the highest among patients with respiratory acidosis (4/9 = 44.4%), followed by those having metabolic acidosis (3/8 = 37.5%). Median length of hospital and intensive care unit stay was 15.75 days and 6.25 days for those with abnormal ABG and 11 and 3.5 days among those with normal ABG. Median health-care expe...
