the results have shown that among twelve isolated bacterial strains, three strains were screened based on their enzymatic potential, and were later identified by 16S rRNA gene sequencing, i.e. showing that the strains belong to the genus Pseudomonas aeruginosa, and Bacillus wiedmannii with a similarity percentage of 99.33% and 100%, respectively, with their corresponding type of strains.

Genomic composition has been found to be species specific and is used to differentiate bacterial species. To date, almost no published composition-based approaches are able to distinguish between most closely related organisms, including intra-genus species and intra-species strains. Thus, it is necessary to develop a novel approach to address this problem.

Targeted PCR amplicon sequencing (TAS) techniques provide a sensitive, scalable, and cost-effective way to query and identify closely related bacterial species and strains. Typically, this is accomplished by targeting housekeeping genes that provide resolution down to the family, genera, and sometimes species level.

Phosphorus plays a major role in growth and development of crops and is often found limiting in almost all types of soils. Phosphorus (P) solubilizing bacteria do the vital processes of mobilization of P from its poorly available sources. In this study, the potency of five bacterial strains (2 strains of Bacillus and 3 strains of Burkholderia) have been evaluated to solubilize P from complexes of Ca-P, Al-P, Fe(II)-P and Fe(III)-P.

Tungrymbai is a traditional fermented dish of the Khasi and Jaintia tribes of Meghalaya. In this study an attempt was made to standardize the preparation of “Tungrymbai” using Lactobacillus fermentum and Lactobacillus plantarum culture obtained from fermented foods of Meghalaya. Three samples were prepared and the bacterial strain was added aseptically to the cooked soybeans in a combination of 1:1 ratio at 1, 2 and 3% culture combination respectively, a traditional sample was used as control. The samples were fermented at 37˚C for 3-4 days.

Typhoid fever is a systemic infection caused by Salmonella enterica subspecies enterica serovar Typhi. A very similar but often less severe disease is caused by S. paratyphi A, B and sometimes C. Enteric fever is endemic in all parts of India. S. typhi and S. paratyphi A are the predominant types of Salmonella responsible of enteric fever in India. An antibiogram is the result of a laboratory testing for the sensitivity of an isolated bacterial strain to different antibiotics.

Scrub typhus is a bacterial zoonosis caused by Orientia tsutsugamushi. Timely diagnosis is necessary as the disease presents with varied signs, symptoms and may progresses to multiorgan dysfunction syndrome. Scrub typhus shows wide antigenic variation, one of the methods for its detection is IFA. There is scarcity of data regarding antigenic variations of Orientia tsutsugamushi which is of importance in our country. About 100 serum samples were collected from patients who had fever for > 7days (excluding other causes of fever).

As infection with Pasteurella multocida is common in cattle and buffalo, a monoclonal antibody based sandwich ELISA kit was developed for its rapid and easy detection. The test was optimized and standardized so that maximum concordance could be maintained with the standard procedures of hemorrhagic septicemia diagnosis recommended by the WHO expert committee. HS-1, a Pasteurella multocida type B specific monoclonal antibody developed in mice was used as tracing antibody to capture P. multocida serotype B:2 in a sandwich ELISA.

K. pneumoniae is responsible for a wide variety of hospital and community-acquired infections, affecting patients with normal immune systems as well as those with pre-existing conditions. The Carbapenems are β-lactam antibiotics that are used in the treatment of infections caused by Extended Spectrum beta-Lactamases (ESBL) producing gram negative bacteria (GNB). Carbapenem antibiotics are considered the drugs of choice for the treatment of ESBL -producing Enterobacteriaceae and other multidrug resistant bacteria.

The increase in prevalence of antimicrobial-resistant bacteria (ARB) is currently a serious threat, thus there is a need for new antimicrobial compounds to combat infections caused by these ARB. An antimicrobial-producing bacterium, Burkholderia paludis was recently isolated and was able to produce a type of siderophore with antimicrobial properties, later identified as pyochelin. The chelating ability of pyochelin has been well-characterized but not for its antimicrobial characteristics. It was found that pyochelin had MIC values (MBC values) of 3.13 mg/mL (6.26 mg/mL) and 6.26 mg/mL (25.

Type VI secretion systems and tailocins, two bacterial phage tail-like particles, have been reported to foster interbacterial competition. Both nanostructures enable their producer to kill other bacteria competing for the same ecological niche. Previously, type VI secretion systems and particularly R-type tailocins were considered highly specific, attacking a rather small range of competitors. Their specificity is conferred by cell surface receptors of the target bacterium and receptor-binding proteins on tailocin tail fibers and tail fiber-like appendages of T6SS.

Several microbial pathogens have been reported to interact with glycosaminoglycans (GAGs) on cell surfaces and in the extracellularmatrix. Herewe demonstrate thatM protein, a major surface-expressed virulence factor of the human bac-terial pathogen, Streptococcus pyogenes, mediates binding to various forms of GAGs. Hence, S. pyogenesstrains expressing a large number of different types of M proteins bound to dermatan sulfate (DS), highly sulfated fractions of heparan sulfate (HS) and heparin, whereas strains deficient in M protein surface expression failed to interact with these GAGs. ...
