Salmonella enterica serovar Typhi and Paratyphi usually cause enteric fever in humans characterized by fever and gastrointestinal symptoms such as diarrhea. Bacteremia is a constant feature of enteric fever, and occasionally, dissemination of bacilli throughout the body results in the establishment of one or more localized foci of persisting infection. This happens especially in patients with preexisting conditions such as hemoglobinopathies, previous joint trauma, surgery, connective tissue diseases, lymphoma, diabetes, alcoholism, immunosuppressive state, and extremes of ages. Rarely, these extraintestinal Salmonella infection cases have also been reported in immunocompetent individuals without any obvious predisposing factors. Salmonella osteomyelitis, a rare sequelae of typhoid, may occur as a result of hematogenous seeding of the bone or joints due to a bacteremic episode. It may also spread from nearby areas of infection or penetrating trauma. Timely diagnosis and treatment of this condition are necessary because if left untreated, it can lead to permanent functional deficits later on. We hereby present a case series with brief review of literature on Salmonella osteomyelitis in immunocompetent patients without any known predisposing conditions over a period of 1 year (2017–2018) from a Tertiary Care Teaching Hospital in Uttarakhand, India.
Background and Objectives: Sphingomonas paucimobilis is an opportunistic pathogen and was rarely encountered in clin- ical specimens previously. This study aimed to investigate the clinical features, associated co-morbidities, and antimicrobial susceptibility patterns of S. paucimobilis infection in a tertiary hospital in Uttarakhand. Materials and Methods: S. paucimobilis isolates cultured from various sections of hospital and OPDs were identified and an- alyzed for their antibiograms in the microbiology laboratory for a duration of one year from January 2020 to December 2020. Results: S. paucimobilis was isolated from 49 samples (0.01%) out of 3792 samples processed in VITEK 2 Compact auto- mated ID/AST instrument. The maximum number of isolates were obtained from urine samples (31%), followed by blood (24%). Septicemia (41%), meningitis (17%), lower respiratory tract infections and ventilator associated pneumonia (14%) constituted a major portion of infections caused by this organism. Diabetes mellitus (22%) and steroid usage (16%) were major associated co-morbid conditions. Third and Fourth generation cephalosporins like ceftriaxone (81%) and cefepime (86%) were found to be the most susceptible drugs whereas 61% of isolates were resistant to colistin. Conclusion: This organism is an up-and-coming pathogen and should not be simply labeled as a contaminant. Although the organism is not grossly virulent and still might not be associated with serious life-threatening infections; however their evolving resistance patterns and increased spectrum of infections should be seriously taken into account.
Introduction Invasive fungal infections have always been a major cause of mortality and morbidity and are especially prevalent in the immunosuppressed groups of patients. Members of the Mucoracea family have an increasing incidence and prevalence. It has always been difficult to diagnose this condition due to various reasons. Materials and Methods This was an observational study carried out jointly by the Department of Microbiology and the Department of Pathology for a duration of one year. All patients who presented in various clinical departments with a high index of clinical suspicion for mucormycosis were included in this study. A total of 186 samples were received from suspected cases of mucormycosis and were all subjected to direct microscopy by potassium hydroxide (KOH), fungal culture, and histopathological examination. Results Mucormycosis was documented in 33 out of 186 cases on direct microscopy, whereas 21 were positive on fungal culture. Histopathological positivity was reduced with only 11 cases showing aseptate hyphae suggestive of mucormycosis. Conclusion As these organisms generally do not grow well on routine culture media and with the histopathological results also being not suggestive clearly of mucormycosis, direct microscopy thus becomes more important and essential in the rapid diagnosis of this deadly condition.
Background: Infectious Keratitis (Ik) Is A Potential Vision-Threatening Ocular Infection Caused By A Variety Of Microorganisms. Aim: To Explore Risk Factors And Etiological Agents Associated With Ik. Design: A Prospective Cross-Sectional Study In Which Corneal Scrapings From 120 Suspected Cases Were Evaluated At A Tertiary Health Care Institute From January To December 2019. Methods: Scrapings Were Subjected To Direct Microscopy, Culture, And Identification By Both Conventional Methods And Maldi-Tof-Ms. The Patient's Demographic Data And Predisposing Factors, If Any Were Recorded. Results: The Mean Age Of Patients Was 48.9 Years And Predisposing Factors Were Documented In 46% (55/120) Of Cases. Overall, Infective Etiology Could Be Established In 51% ( N = 61/120) Of Cases. Fungal Growth In 26% ( N = 31/120) Of Cases And Bacterial Growth In 22% ( N = 27/120) Of Cases Was Obtained. Growth Of More Than One Species Of Fungi Or Growth Of Bacteria Along With Fungus Were Observed In 2% ( N = 3/120) Of Cases. Of All The Fungal Isolates Obtained ( N = 34), The Most Common Isolate Was Fusarium (18/34) Followed By Aspergillus (8/34), Curvularia (4/34), Pseudallescheria Boydii (3/34), And Geotrichum (1/34). Among The Gram-Positive Bacterial Isolates ( N = 16), Staphyloccus Species (15/16) Were Isolated In Maximum Number Followed By Streptococcus Pneumoniae (1/16). Among The Gram-Negative Isolates ( N = 13), Pseudomonas Species (8/13) Were Isolated In Maximum Number Of Cases, Followed By Acinetobacter (3/13), Klebsiella Pneumoniae (1/13), And Escherichia Coli (1/13). Conclusion: For Initiating Appropriate Empirical Therapy, The Knowledge Of The Epidemiological Pattern Of Infectious Keratitis Of A Particular Geographical Region Is Crucial.
Coexisting tuberculosis (TB) and hydatid disease in an immunocompetent individual is an extremely rare occurrence. Given the similarities in the clinical manifestations and morbidities of both, specific diagnosis in individuals coinfected with these is difficult. We, hereby present a case of a 17-year-old adolescent man diagnosed to be a coinfection of pulmonary TB with pulmonary and cardiac hydatid disease, with the review of cases having a similar presentation. The coexistence of these infections should be considered in endemic areas. Management can only be done by a multidisciplinary approach including surgical, microbiological, histopathological and radiological facilities. Complete surgical excision of the cyst is the treatment of choice and medical therapy for both aetiologies should be appropriate to achieve cure.
