Introduction: Acinetobacter baumanii (AB) is a bacterium of concern in the hospital setup due to its ability to thrive in unfavorable conditions and the rapid emergence of antibiotic resistance. Carbapenem resistance in this organism is disheartening, further clouded by the emergence of colistin resistance.

Aim: The present prospective study aims to note the epidemiology, molecular profile, and clinical outcome of patients with colistin resistance AB infections in a multispecialty tertiary care setup in Odisha, Eastern India.

White spot disease, caused by white spot syndrome virus (WSSV), has historically been the most devastating disease in shrimp aquaculture industry across the world. The mode of virus transmission is the most crucial stage in the dynamics and management of virus infection. This study explored the mechanism of vertical transmission of WSSV in Indian white shrimp, Penaeus indicus, potential native species for domestication and genetic improvement, using quantitative real time PCR (q RT PCR), light and electron microscopy, and in situ hybridization.

Background: Compared to conventional microscopy, the cartridge-based nucleic acid amplification test (CBNAAT, Xpert MTB/RIF, Cepheid, USA) has the dual advantage of higher sensitivity to detect Mycobacterium tuberculosis (M. tb), and the ability to detect rifampicin resistance.

Aim: To evaluate the impact of the CBNAAT on the detection of pulmonary and extra-pulmonary tuberculosis from private and public healthcare facilities in Bhubaneswar, Odisha.

Article Synopsis
  • - The study addresses the rising issue of antibiotic resistance in bacteria, specifically focusing on carbapenem-resistant Enterobacterales (CRE), CRAB, and CRPA, which has led to the use of older antibiotics like colistin, despite emerging resistance to it.
  • - Researchers evaluated colistin susceptibility in 6,013 carbapenem-resistant isolates using three methods: broth microdilution (BMD), colistin broth disc elution (CBDE), and Vitek two, comparing their effectiveness based on various accuracy metrics (e.g., sensitivity and specificity).
  • - Results indicated a colistin resistance rate of 12.9% among the isolates, with Vitek two showing high sensitivity (78.2–84.

Spinal epidural abscess (SEA) is a rarest form of spinal infections and is characterized by the presence of pus in the space between the dura mater, and the osseoligamentous confines of the vertebral canal. This can cause spinal injury due to direct compression or local ischemia. The major etiology of SEA is bacterial and tuberculous in endemic regions.
