Meningitis in patients with ventriculo-peritoneal shunt (VP shunt) caused by various species of Candida have been widely described in literature. However, reports describing Candida auris as a cause of meningitis is limited. In this case report we describe a case of multidrug resistant Candida auris meningitis secondary to VP shunt infection successfully treated with intrathecal amphotericin B deoxycholate and intravenous liposomal amphotericin B.

Monkeypox (MPX) is a zoonotic disease caused by the monkeypox virus (MPXV) belonging to the genus. It results in a smallpox-like disease in humans. Recently, MPX has been declared a public health emergency of international concern.

Article Synopsis
  • MBL genes in gram-negative bacteria (GNB) pose a serious risk due to their transmission via mobile genetic elements, necessitating early detection of these organisms.
  • The study aimed to find a sensitive and cost-effective screening test for detecting carbapenemase-producing isolates, using methods such as Modified Hodge Test (MHT), Etest, and Combined Disc Test, alongside PCR for various resistance genes.
  • Results showed that MHT on MacConkey Agar was the most effective and cost-efficient method for detecting MBL production compared to PCR, while 2MPA was less effective as an inhibitor than EDTA.

is a rare cause of appendicitis, skin soft tissue, and bloodstream infections. The clinical significance of its isolation from samples of skin or soft tissues and pus from the appendix is poorly understood. Invasive pneumococcal disease (IPD) continues to be a problem in India, associated with a high case fatality rate despite treatment facilities available in the hospital settings.

Article Synopsis
  • - The study aimed to determine how common carbapenemase-producing bacteria are and evaluate various testing methods to identify them compared to the trusted genetic tests.
  • - The findings revealed that 65% of the tested bacteria were resistant to carbapenem antibiotics.
  • - The phenotypic testing methods assessed are affordable and suitable for laboratories with limited resources, making them useful for screening carbapenem resistance.

, a recently identified multiresistant Candida species, was first reported in Japan in 2009. It is different from other pathogenic yeast species because of its propensity to cause outbreaks and transmits between patients within health care settings. The invasive infections caused by are associated with high mortality rates, approaching 70% particularly in intensive care unit patients.

Article Synopsis
  • The study aimed to assess how common Postoperative central nervous system infections (PCNSIs) are and to analyze the antibiotic resistance of the bacteria causing these infections in trauma patients who underwent neurosurgery.
  • Conducted over four years, the research included 961 patients who met the criteria for PCNSIs, revealing a prevalence of 7.2%, primarily affecting males with an average age of 31.9 years.
  • The findings indicated that 91.6% of the pathogens were Gram-negative bacteria, with a notable 41% being multidrug-resistant, which raises significant concerns for effective treatment options.

Background & Objectives: Nosocomial infections caused by multidrug-resistant, Pseudomonas species have become a major clinical and public health concern. The aim of this study was to characterize phenotypic and genotypic profile of antimicrobial resistance (AMR) in Pseudomonas spp. isolated from hospitalized patients.

Introduction: has now emerged as a significant nosocomial pathogen in health-care setting ESP in intensive care units. Rapidly growing resistance among clinical isolates suggests a need to detect resistance mechanisms in this organism. The present study was designed to compare the various phenotypic tests available with the gold standard of genotype.

Article Synopsis
  • The study aimed to assess the prevalence and resistance profiles of specific bacteria isolated from clinical samples using various testing methods.
  • Among 196 unique strains analyzed, high rates of resistance to antibiotics were observed, with extended spectrum beta-lactamases (ESBLs) and carbapenemase production being particularly notable.
  • The findings suggest that integrating both phenotypic and genotypic testing methods is essential for accurately understanding the resistance characteristics of these bacteria.

Gas gangrene is a necrotic infection of the skin and soft tissue that is associated with high mortality and often necessitating amputation to control the infection. Clostridial myonecrosis is most often cause of gas gangrene and usually present in settings of trauma, surgery, malignancy, and other underlying immunocompromised conditions. The most common causative organism of clostridial myonecrosis is followed by .

We report a rare case of post-traumatic cutaneous diphtheria in a patient referred from a hospital in rural India. The diagnosis of cutaneous diphtheria was confirmed by the isolation of Corynebacterium diphtheriae cultured from the ulcer of the leg, along with Staphylococcus aureus, Streptococcus pyogenes, and Arcanobacterium haemolyticum. The patient was kept on isolation and treated with erythromycin for 14 days without antitoxin.

() is a non-fermenting gram negative organism that is commonly detected in the soil and water but is rarely reported to cause human infection. However it is emerging as a nosocomial pathogen in patients admitted in intensive care units (ICUs). Infections caused by this organism have a high mortality rate due to lack of effective therapeutic regimens and its intrinsic resistance to multiple antibiotics.

Purpose: This study was undertaken to evaluate the efficiency of the pyrosequencing (PSQ) assay for the rapid detection of resistance to rifampicin (RIF), fluoroquinolones (FQs) and second-line injectables (SLIs) such as capreomycin (CAP) and kanamycin (KAN) in Mycobacterium tuberculosis (Mtb) clinical isolates.

Methodology: Pyrosequencing is a simple and accurate short read DNA sequencing method for genome analysis. DNA extraction from Mtb clinical isolates was performed using Tris-HCl buffer and chloroform.
