Plasmid mediated antimicrobial resistance in the Enterobacteriaceae is a global problem . The rise of CTX-M class extended spectrum beta lactamases ( ESBLs ) has been well documented in industrialized countries . Vietnam is representative of a typical transitional middle income country where the spectrum of infectious ...
Shigellosis is a disease caused by bacteria belonging to Shigella spp . and is a leading cause of bacterial gastrointestinal infections in infants in unindustrialized countries . The Shigellae are dynamic and capable of rapid change when placed under selective pressure in a human population . Extended spectrum beta lac...

Burkholderia pseudomallei is the causative agent of melioidosis , a severe infection prominent in northern Australia and Southeast Asia . The “gold standard” for melioidosis diagnosis is bacterial isolation , which takes several days to complete . The resulting delay in diagnosis leads to delayed treatments , which cou...
An outer membrane component , capsular polysaccharide ( CPS ) , is a virulence factor expressed by many Gram-negative bacteria including Burkholderia pseudomallei , the causative agent of melioidosis . Recently , B . pseudomallei CPS was identified as a useful diagnostic biomarker , leading to the development of a late...

Recent studies of cellular networks have revealed modular organizations of genes and proteins . For example , in interactome networks , a module refers to a group of interacting proteins that form molecular complexes and/or biochemical pathways and together mediate a biological process . However , it is still poorly un...
Protein–protein interactions mediate numerous biological processes . In the last decade , there have been efforts to comprehensively map protein–protein interactions occurring in an organism .

The evolution of signal transduction pathways is constrained by the requirements of signal fidelity , yet flexibility is necessary to allow pathway remodeling in response to environmental challenges . A detailed understanding of how flexibility and constraint shape bacterial two component signaling systems is emerging ...
Survival in a changing world requires signal transduction circuitry that can evolve to sense and respond to new environmental challenges . The Firmicute sporulation initiation ( Spo0 ) pathway is a compelling example of a pathway with a circuit diagram that has changed over the course of evolution . In Clostridium acet...

Ubiquitination relies on a subtle balance between selectivity and promiscuity achieved through specific interactions between ubiquitin-conjugating enzymes ( E2s ) and ubiquitin ligases ( E3s ) . Here , we report how a single aspartic to glutamic acid substitution acts as a dynamic switch to tip the selectivity balance ...

In gregarious species , social interactions maintain group cohesion and the associated adaptive values of group living . The understanding of mechanisms leading to group cohesion is essential for understanding the collective dynamics of groups and the spatio-temporal distribution of organisms in environment . In this v...
Terrestrial isopods , commonly named woodlice or pill bugs , are commonly distributed soil-dwelling arthropods , particularly important in soils as macro-decomposers of leaf litter . Many species of woodlice are synanthropic and , for this reason , are easily observable in gardens , urban parks or composts . Harmless o...

Behavioural Contagion Explains Group Cohesion in a Social Crustacean
Genome sequences of several economically important phytopathogenic oomycetes have revealed the presence of large families of so-called RXLR effectors . Functional screens have identified RXLR effector repertoires that either compromise or induce plant defense responses . However , limited information is available about...
Phytophthora species are among the most devastating crop pathogens worldwide . P . infestans is a pathogen of tomato and potato plants . The genome of P . infestans has been sequenced , revealing the presence of a large number of host-targeting RXLR effector proteins that are thought to manipulate cellular activities t...

Functionally Redundant RXLR Effectors from Phytophthora infestans Act at Different Steps to Suppress Early flg22-Triggered Immunity
Brucellosis is a neglected tropical zoonosis allegedly reemerging in Middle Eastern countries . Infected ruminants are the primary source of human infection; consequently , estimates of the frequency of ruminant brucellosis are useful elements for building effective control strategies . Unfortunately , these estimates ...
Brucellosis is a zoonosis of mammals caused by bacteria of the genus Brucella . It is responsible for a vast global burden imposed on human health through disability and on animal productivity . In humans brucellosis causes a range of flu-like symptoms and chronic debilitating illness . In livestock brucellosis causes ...

Ruminant Brucellosis in the Kafr El Sheikh Governorate of the Nile Delta, Egypt: Prevalence of a Neglected Zoonosis
Understanding the prevalence of sexual reproduction in eukaryotes is a hard problem . At least two aspects still defy a fully satisfactory explanation , the functional significance of genetic recombination and the great variation among taxa in the relative lengths of the haploid and diploid phases in the sexual cycle ....
Sexual reproduction involves an alternation of ploidy . Haploid gametes , carrying a single set of chromosomes , fuse to form a diploid zygote with a double set of chromosomes . The gametes are formed from diploid progenitor cells by meiosis , which involves genetic recombination—the key evolutionary aspect of sexual r...
