Biography

University of Pune University of Pune -Main Building 1.JPG
University of Pune

Dipshikha Chakravortty was born in 1968 [2] at Jabalpur, in the second largest Indian state of Madhya Pradesh to Santosh Kumar Chakravortty and Bani Chakravortty. [3] Her early schooling was in Mumbai where the family had moved soon after her birth. After earning a bachelor's degree in microbiology from LAD College for Women of Rashtrasant Tukadoji Maharaj Nagpur University, and a master's degree in microbiology from the University of Nagpur. She did her doctoral studies, assisted by junior and senior research fellowships, under the guidance of K. S. Nandakumar at the National Centre for Cell Science which secured her a Ph.D. from Savitribai Phule Pune University. [4] Thereafter, she moved to Japan for her post-doctoral studies and completed it under the supervision of Takashi Yokochi of Aichi Medical University. Subsequently, she took up a research position at the laboratory of Michael Hensel in Erlangen, Germany, and worked there on an Alexander von Humboldt fellowship. On her return to India in 2004, she joined the Department of Microbiology and Cell Biology of the Indian Institute of Science (IISc) as a faculty, [5] where she holds the position of a professor. [4] At IISc, she has established her laboratory, Molecular Pathogenesis Lab [6] and hosts a number of researchers and scholars. [7]

Chakravortty resides at IISc Campus, in Bengaluru, Karnataka. [2]

Professional profile

Salmonella. SalmonellaNIAID.jpg
Salmonella.

Chakravortty's research focus is on antibacterial resistance with special emphasis on Salmonella [5] and she is known to have done work on the pathogenesis of Salmonella Typhimurium, a gram negative bacterium pathogen. [8] Her laboratory works on diseases such as Typhoid, and the host-pathogen interaction with regard to the disease, with a view to develop a vaccine with a long-time memory against the pathogen. [6] The team led by her has been successful in developing a treatment protocol for sepsis which uses a Bactericidal/permeability-increasing protein, a type of glycoprotein, which has been found to neutralize the bacterial endotoxin, one of the primary causative factors of sepsis. [9] Her studies have been documented by way of a number of articles [10] [note 1] and ResearchGate, an online repository of scientific articles has listed 169 of them. [11] Besides, she has contributed chapters to books edited by others. [12] She has also mentored many research scholars in their doctoral studies. [7] [13]

Dipshikha Chakravortty was a Hostel Chair during the critical time of the Covid Pandemic from 2019 to 2021 Jan, during which she along with the team established the Student isolation center and took care of more than 4500 students. Personally, she has taken care of them and nurtured their mental well-being during this critical phase. Her mentorship skills lead the young students from her group to take up various leading positions in institutes and other Universities, including IISc. Apart from taking care of students from Biological Sciences, she also took care of students across the division. During Dipshikha’s tenure as a Hostel Chair, she has been subjected to the harsh reality of Covid in the hostel. It is then that she created a group “ Cheers in Quarantine” where all the students who got into isolation were taken care of and kept entertained by keeping their morale high. During that time she conducted various online musical evenings and fun time, so that everybody is in good spirits. Her extreme dedication and love for the students got her the nickname “Mother India”. One of her poems which she wrote and read during one of the online evenings,

Feverish, headache, body ache
No smell, no taste, all taste same
Nose got Dugged and throat got swabbed
Went to the lab to get it cracked
Sitting in the room and spending time
Where 1 sec seems 1 year
Tring Tring Tring , rang the phone
Heart raced fast and mind went blank
Positive, Negative, Positive, Negative
Finally announced Positive
Pack your bags and take your essentials
Wondering what went wrong
Wore mask and used sanitizers
Where did I go wrong, What did I do wrong
Virus tricked every way
Got inside and pave its way
14 days of Quarantine will make it go away
Not to Worry
CHEERS IN QUARANTINE
Prof Dipshikha Chakravortty, also wrote a preface for the Book with a beautiful piece composed by her
RIGHT TO LIVE
We are tiny We are small
You need microscope to see us all
Still we are mighty and will kill you all
Give us stress, Give us pain
Still your efforts will go in vain
We are community, strong and high
Treat us with respect and we will treat you right
We were not bad, but you made us so
We will become worse if you continue to do so
Hold back and keep quiet
We will be in harmony throughout our life!
( REF- Preface By Dipshikha Chakravortty for the Book-Resistance- Tales from post-antibiotic world, 2019)

<i>Salmonella</i> Genus of bacteria

Salmonella is a genus of rod-shaped (bacillus) gram-negative bacteria of the family Enterobacteriaceae. The two known species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,650 serotypes. Salmonella was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon.

<i>Salmonella enterica</i> Species of bacterium

Salmonella enterica is a rod-shaped, flagellate, facultative anaerobic, Gram-negative bacterium and a species of the genus Salmonella. It is divided into six subspecies, arizonae (IIIa), diarizonae (IIIb), houtenae (IV), salamae (II), indica (VI), and enterica (I). A number of its serovars are serious human pathogens; many of them are serovars of Salmonella enterica subsp. enterica.

Adhesins are cell-surface components or appendages of bacteria that facilitate adhesion or adherence to other cells or to surfaces, usually in the host they are infecting or living in. Adhesins are a type of virulence factor.

<i>Burkholderia mallei</i> Species of bacterium

Burkholderia mallei is a Gram-negative, bipolar, aerobic bacterium, a human and animal pathogen of genus Burkholderia causing glanders; the Latin name of this disease (malleus) gave its name to the species causing it. It is closely related to B. pseudomallei, and by multilocus sequence typing it is a subspecies of B. pseudomallei.B. mallei evolved from B. pseudomallei by selective reduction and deletions from the B. pseudomallei genome. Unlike B. pseudomallei and other genus members, B. mallei is nonmotile; its shape is coccobacillary measuring some 1.5–3.0 μm in length and 0.5–1.0 μm in diameter with rounded ends.

<i>Yersinia pseudotuberculosis</i> Species of bacterium

Yersinia pseudotuberculosis is a Gram-negative bacterium that causes Far East scarlet-like fever in humans, who occasionally get infected zoonotically, most often through the food-borne route. Animals are also infected by Y. pseudotuberculosis. The bacterium is urease positive.

<span class="mw-page-title-main">Polymyxin B</span> Antibiotic medication

Polymyxin B, sold under the brand name Poly-Rx among others, is an antibiotic used to treat meningitis, pneumonia, sepsis, and urinary tract infections. While it is useful for many Gram negative infections, it is not useful for Gram positive infections. It can be given by injection into a vein, muscle, or cerebrospinal fluid or inhaled. The injectable form is generally only used if other options are not available. It is also available as the combinations bacitracin/polymyxin B and neomycin/polymyxin B/bacitracin for use on the skin.

<span class="mw-page-title-main">Microbiology of Lyme disease</span>

Lyme disease, or borreliosis, is caused by spirochetal bacteria from the genus Borrelia, which has 52 known species. Three species are the main causative agents of the disease in humans, while a number of others have been implicated as possibly pathogenic. Borrelia species in the species complex known to cause Lyme disease are collectively called Borrelia burgdorferisensu lato (s.l.), not to be confused with the single species Borrelia burgdorferi sensu stricto, a member of the complex, which is responsible for nearly all cases of Lyme disease in North America.

<i>Burkholderia thailandensis</i> Species of bacterium

Burkholderia thailandensis is a nonfermenting motile, Gram-negative bacillus that occurs naturally in soil. It is closely related to Burkholderia pseudomallei, but unlike B. pseudomallei, it only rarely causes disease in humans or animals. The lethal inoculum is approximately 1000 times higher than for B. pseudomallei. It is usually distinguished from B. pseudomallei by its ability to assimilate arabinose. Other differences between these species include lipopolysaccharide composition, colony morphology, and differences in metabolism.

<span class="mw-page-title-main">Hfq protein</span>

The Hfq protein encoded by the hfq gene was discovered in 1968 as an Escherichia coli host factor that was essential for replication of the bacteriophage Qβ. It is now clear that Hfq is an abundant bacterial RNA binding protein which has many important physiological roles that are usually mediated by interacting with Hfq binding sRNA.

<span class="mw-page-title-main">Virulence-related outer membrane protein family</span>

Virulence-related outer membrane proteins, or outer surface proteins (Osp) in some contexts, are expressed in the outer membrane of gram-negative bacteria and are essential to bacterial survival within macrophages and for eukaryotic cell invasion.

An Hfq binding sRNA is an sRNA that binds the bacterial RNA binding protein called Hfq. A number of bacterial small RNAs which have been shown to bind to Hfq have been characterised . Many of these RNAs share a similar structure composed of three stem-loops. Several studies have expanded this list, and experimentally validated a total of 64 Hfq binding sRNA in Salmonella Typhimurium. A transcriptome wide study on Hfq binding sites in Salmonella mapped 126 Hfq binding sites within sRNAs. Genomic SELEX has been used to show that Hfq binding RNAs are enriched in the sequence motif 5′-AAYAAYAA-3′. Genome-wide study identified 40 candidate Hfq-dependent sRNAs in plant pathogen Erwinia amylovora. 12 of them were confirmed by Northern blot.

<span class="mw-page-title-main">Viable but nonculturable</span>

Viable but nonculturable (VBNC) bacteria refers as to bacteria that are in a state of very low metabolic activity and do not divide, but are alive and have the ability to become culturable once resuscitated.

<i>Salmonella enterica <span style="font-style:normal;">subsp.</span> enterica</i> Subspecies of bacterium

Salmonella enterica subsp. enterica is a subspecies of Salmonella enterica, the rod-shaped, flagellated, aerobic, Gram-negative bacterium. Many of the pathogenic serovars of the S. enterica species are in this subspecies, including that responsible for typhoid.

<i>Proteus penneri</i> Species of bacterium

Proteus penneri is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It is an invasive pathogen and a cause of nosocomial infections of the urinary tract or open wounds. Pathogens have been isolated mainly from the urine of patients with abnormalities in the urinary tract, and from stool. P. penneri strains are naturally resistant to numerous antibiotics, including penicillin G, amoxicillin, cephalosporins, oxacillin, and most macrolides, but are naturally sensitive to aminoglycosides, carbapenems, aztreonam, quinolones, sulphamethoxazole, and co-trimoxazole. Isolates of P. penneri have been found to be multiple drug-resistant (MDR) with resistance to six to eight drugs. β-lactamase production has also been identified in some isolates.

<span class="mw-page-title-main">OmpT</span> Bacterial protein

OmpT is an aspartyl protease found on the outer membrane of Escherichia coli. OmpT is a subtype of the family of omptin proteases, which are found on some gram-negative species of bacteria.

The alpha-D-phosphohexomutases are a large superfamily of enzymes, with members in all three domains of life. Enzymes from this superfamily are ubiquitous in organisms from E. coli to humans, and catalyze a phosphoryl transfer reaction on a phosphosugar substrate. Four well studied subgroups in the superfamily are:

  1. Phosphoglucomutase (PGM)
  2. Phosphoglucomutase/Phosphomannomutase (PGM/PMM)
  3. Phosphoglucosamine mutase (PNGM)
  4. Phosphoaceytlglucosamine mutase (PAGM)
<span class="mw-page-title-main">OSU-03012</span> Chemical compound

OSU-03012 (AR-12) is a celecoxib derivative with anticancer and anti-microbial activity. Unlike celecoxib, OSU-03012 does not inhibit COX, but inhibits several other important enzymes instead which may be useful in the treatment of some forms of cancer, When combined with PDE5 inhibitors such as sildenafil or tadalafil, OSU-03012 was found to show enhanced anti-tumour effects in cell culture.

When considering pathogens, host adaptation can have varying descriptions. For example, in the case of Salmonella, host adaptation is used to describe the "ability of a pathogen to circulate and cause disease in a particular host population." Another usage of host adaptation, still considering the case of Salmonella, refers to the evolution of a pathogen such that it can infect, cause disease, and circulate in another host species.

Proteobiotics are natural metabolites which are produced by fermentation process of specific probiotic strains. These small oligopeptides were originally discovered in and isolated from culture media used to grow probiotic bacteria and may account for some of the health benefits of probiotics.

<span class="mw-page-title-main">IsrM small RNA</span>

The IsrM RNA is a small non-coding RNA discovered in Salmonella pathogenicity island, which is not found in E.coli. It is important for invasion of epithelial cells, intracellular replication inside macrophages, virulence and colonisation in mice. It targets the SopA and HilE mRNAs, virulence factors essential for bacterial invasion. It is a first pathogenicity island-encoded sRNA shown to be directly involved in Salmonella pathogenesis.
