Tuberculosis, caused by bacteria in the Mycobacterium tuberculosis complex (MTBC), is a major global public health burden. Strain-specific genomic diversity in the known lineages of MTBC is an important factor in pathogenesis that may affect virulence, transmissibility, host response and emergence of drug resistance.

Campylobacter rectus (CR) is an exclusively oral, Gram-negative anaerobe and mobile bacterium that shows a wide range of virulence factors. A 41-year-old woman came to the emergency department because she felt intense radiating pain in the whole abdomen.

Diphtheria remains a major public health concern with multiple recent outbreaks around the world. Moreover, invasive non-toxigenic strains have emerged globally causing severe infections. A diphtheria epidemic in the former Soviet Union in the 1990s resulted in ~5000 deaths. In this study, we analysed the genome sequences of a collection of 93 C. diphtheriae strains collected during and after this outbreak (1996 – 2014) in a former Soviet State, Belarus to understand the evolutionary dynamics and virulence capacities of these strains.

Ural genetic family is a part of the Euro-American lineage of Mycobacterium tuberculosis and is endemic in Northern Eurasia (former Soviet Union [FSU]). These strains were long described as drug susceptible and of low virulence, but recent studies reported an increasing circulation of the multidrug-resistant (MDR) and extensively drug-resistant (XDR) Ural strains.

Regulatory circuits of infection in the emerging experimental model system, water flea Daphnia and their microparasites, remain largely unknown. Here we provide the first molecular insights into the response of Daphnia galeata to its highly virulent and common parasite Caullerya mesnili, an ichthyosporean that infects the gut epithelium.

S.epidermidis previously dismissed as contaminants is now emerged as one of the major nosocomial pathogens exhibiting resistance to various drugs including Methicillin. Their ability to form biofilms contributes to their pathogenicity contributing to increased drug resistance. Proper infection control services can certainly bring the rates of this virulent bacteria down in hospitals. The study was conducted for a period of 6 months (Febrauary 2019 to July 2019).

Shewanella algae is an emerging pathogen with an increasing rate of association in clinical samples worldwide. Exposure to marine and brackish waters has frequently been linked to human infection. The present study has examined the prevalence of the bacterium in shrimp which is a brackish water crop. The bacterium was isolated from about 8% of the shrimps’ samples cultured and sold in different parts of West Bengal, India. The isolates produced hemolysin and were thus considered virulent. An increase in the occurrence of human infections caused by S.

Over the years, agriculture across the world has been compromised by a succession of devastating epidemics caused by evolving viruses that spilled over from reservoir species or by new variants of classic viruses that acquired new virulence factors or changed their epidemiological patterns. Population genetics can be used as a powerful tool for identification of disease dynamics over population across large-scale geographic regions. Knowledge of life-history and origin of pathogen can greatly benefit from emergence and expansion of spatial genetics.

Acinetobacter baumannii is an emerging human pathogen causing great concern in hospitals. There are numerous studies regarding the virulence factors that contribute to the pathogenesis of A. baumannii clinical isolates, whereas data regarding environmental isolates are missing. The virulence factors (biofilm formation at the air-liquid/solid-liquid interfaces and surface motility) of A. baumannii isolated from natural environment were determined.

Pseudomonas aeruginosa is a major cause of nosocomial infections. Recently multidrug resistance and extended-spectrum ß-lactamase (ESBL)-producing P. aeruginosa isolates are emerging worldwide. These isolates are reported to be more virulent than the nonmultidrug resistance and non ESBL producing isolates. In order to find a correlation between ESBL production and virulence, we tested one virulence factor involved in pathogenicity- lipase production in ESBL and non ESBL producing isolates. A total of 100 samples were evaluated.

Listeria monocytogenes is an emerging foodborne pathogen of public health concern. Animals may act an asymptomatic carrier and can contaminate foods of animal origin such as meats and dairy products. The objective of the study was to determine the prevalence, pathogenicity and antimicrobial profile of L. monocytogenes in goats and pigs intended for human consumption. A total of 350 samples comprising meat, milk, blood, and faeces of goats and pigs were analysed.

E. coli O157:H7 is an emerging food borne pathogen having zoonotic significance. Though the primary reservoir of this serotype is cattle; Sheep and goat are also considered to be the main reservoir for E. coli O157:H7. Conventional cultural methods are time consuming method and also the specificity is very less. Multiplex PCR (mPCR) tends to be specific, more rapid and reliable.

Antibiotic resistance and the particular emergence of multi - resistant bacterial strains are clinically relevant issue involving serious threats to public health worldwide. DNA methylation, which changes the affinity and interaction of regulatory proteins with DNA, is an epigenetic mechanism that regulates numerous bacterial physiological processes, including chromosome replication, DNA segregation, mismatch repair, transposition and transcription.

The Nipah and Hendra viruses are highly pathogenic paramyxoviruses that recently emerged from flying foxes to cause serious disease outbreaks in humans and livestock in Australia, Malaysia, Singapore and Bangladesh. Their unique genetic constitution, high virulence and wide host range set them apart from other paramyxoviruses. These characteristics have led to their classification into the new genus Henpaviruswithin the family Para-myxoviridae and to their designation as Biosafety Level 4 pathogens. ...
