Enhancing Drought Tolerance in Sorghum Plants through Bacterial Inoculation: A Study on Water Retention and Stomatal Conductance | Chapter 8 | Research Advances in Microbiology and Biotechnology Vol. 9

 The study evaluates the impact of moisture stress tolerant bacterial inoculants on the relative water content and stomatal conductance of sorghum leaves under drought conditions. Drought is one of the major abiotic stresses that adversely affects majority of the world’s crop growth and productivity. The relative water content (RWC) and stomatal conductance (SC) in sorghum (Sorghum bicolor, L.) leaves were assessed under water stress condition by sorghum seed priming with Serratia marcescens strain L1SC8, Pseudomonas putida strain L3SC1, Enterobacter cloacae strain L1CcC1 and Serratia marcescens strain L2FmA4. RWC was higher in leaves of seed priming plants. Water stress resulted in decreased RWC of plant leaves. Seed priming with Serratia marcescens strain L1SC8 showed higher RWC over untreated control followed by Enterobacter cloacae strain L1CcC1. However SC decreased in seed primed stressed plants leaves compared to non-primed stressed plant leaves. Pseudomonas putida strain L3SC1 showed lowest SC as compared to other treatments and control. All the bacterial inoculant increases the RWC. The increase in RWC was statistically significant over control. Thus, the moisture stress tolerant bacterial inoculants sustain the drought condition by increasing the RWC in plant. Thus, seed priming with moisture stress tolerant bacterial cultures increase the RWC while decrease the SC which was the major attributing factors for drought tolerance in sorghum. The findings provide valuable insights into potential strategies for enhancing drought tolerance in crop plants, with implications for agricultural productivity in water- stressed environments. Additionally, the study contributes to the understanding of the role of microbial inoculation in inducing physiological changes in plants to cope with water stress, which is a topic of increasing interest in agricultural research.

A Compilation of Cases Suffering from Pneumonia Caused by Pseudomonas mosselli in Immunocompromised Patients | Chapter 7 | Innovations in Microbiology and Biotechnology Vol. 6

Background: Pseudomonas mosselli is a Gram-negative, rod-shaped, aerobic, non-sporing, motile bacterium that lives in the soil alongside plants and defends them from bacterial and fungal diseases by producing a range of chemicals. It results in opportunistic infections in immunosuppressed individuals. Fever, respiratory discomfort, and a purulent cough are the most typical respiratory infection manifestations. Our research aims to demonstrate the infectious potential of uncommon isolates like Pseudomonas mosselii in immunosuppressed individuals.

Three cases make up our case series. Case 1 had type 2 diabetes mellitus, chronic kidney disease, hypertension, and was also found to be SARS-CoV-2 positive by RT-PCR (Real time polymerase chain reaction). Case 2 had Takosubo cardiomyopathy and was on the verge of going into heart failure. Case 3 had advanced renal failure and was receiving steroid therapy as well as weekly dialysis. From respiratory samples of these individuals who had been hospitalised to a tertiary care facility, Pseudomonas mossellii was identified. Culture features, biochemical processes, and species identification using matrix-assisted laser desorption/ionization-time of flight-mass spectrometry were used for identification (MALDI-TOF-MS).

In conclusion, immunocompromised people who contract opportunistic infections from Pseudomonas mosselii. It may readily be tested for antibiotic susceptibility after causing respiratory infections that can be treated with medicines.

Acute Pediatric Bacterial Meningitis Due to the Rare Isolate, Pseudomonas putida: A Case Report | Chapter 16 | New Frontiers in Medicine and Medical Research Vol. 1

 Acute bacterial meningitis (ABM) is a medical emergency that requires immediate diagnosis and treatment. ABM and its repercussions continue to strike individuals in India, despite the advent of newer, more potent antibiotics, with fatality rates ranging from 16 to 32 percent. The goal of this case report is to describe how Pseudomonas putida was isolated from a sample of cerebrospinal fluid. Apart from that, the author emphasises the need of correctly identifying the organism and, as a result, picking the most appropriate antibiotic from the susceptibility profile to allow for early recovery and improve the patient's outcome and survival.
