Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). When conditions are favourable such as the right temperature and nutrients are available, some bacteria like Escherichia coli can divide every 20 minutes.

The new bacterial strain makes an enzyme called NDM-1 (New Delhi metallo-beta-lactamase 1), which enables a bacterium to become resistant to virtually all antibiotics, even the most powerful ones including carbapenem antibiotics. The enzyme was named after New Delhi, the capital city of India as it is now widespread in India and neighboring country Pakistan, especially in hospitals.
Researchers collected samples of bacteria from patients from various hospitals and community-associated infections in India (Chennai and Haryana), and from individuals referred to the UK’s national reference laboratory between 2007 and 2009.
Besides this, as of June 2010, there were three reported cases of Enterobacteriaceae isolates bearing NDM-1 gene in the US. The researchers are worried about this emerging public health threat and say that it could lead to a serious worldwide public health problem, if not controlled soon.  There are not many anti-Gram-negative antibiotics in development, and not one that is effective against NDM-1. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. In this process the bacterium, which is a single cell, divides into two identical daughter cells. These are dormant structures, which are extremely resistant to hostile physical and chemical conditions such as heat, UV radiation and disinfectants. The isolates were grown in (A) R2A, (B) TYG, (C) nutrient, and (D) Luria broth for 24 and 48 h.

A breakdown on water usage revealed that 70% of freshwater supplies are used for agricultural irrigation.
Environmental and Public Health Implications of Water Reuse: Antibiotics, Antibiotic Resistant Bacteria, and Antibiotic Resistance Genes.
In order to treat such resistant infections, scientists are working on development of next generation antibiotics.
This is concerning because these antibiotics are some of the most powerful ones that are used on hard-to-treat infections that evade other drugs.
The bacterial strain has been brought from that region to Europe by people undergoing surgical treatments in those countries. If the situation is not controlled soon, the medical community could be confronted with carbapenem-resistant Enterobacteriaceae that cause common infections, resulting in treatment failures with significant burden to health-care costs. This is a serious human disease that causes painful tightening of the muscles, usually all over the body. Instead their control centre containing the genetic information is contained in a single loop of DNA. Viral transmission involves a virus (pink, lower left) obtaining a resistant gene, and passing it to a bacterial cell that incorporates it into its plasmid. Isolates were arranged in order of their MICs towards tetracycline and erythromycin, in which PM-ae exhibited the highest MIC towards antibiotics, and vice versa for E20.
The use of reclaimed water as an alternative water source for agricultural irrigation would greatly alleviate the demand on freshwater sources.
Most of us know about penicillin, an antibiotic which was a breakthrough antibiotic when discovered. At this point only tigecycline and colistin (types of antibiotics) had any effect on the NDM-1 producing bacteria.
The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell.

Many endospore-producing bacteria are nasty pathogens, for example Bacillus anthracis is the cause of anthrax. The center of each bubble gives the value of attached biofilm biomass as quantified by crystal violet staining. This paradigm shift is gaining momentum in several water scarce countries like Saudi Arabia.
However, there were some cases in which isolates were resistant to ALL antibiotics according to researchers.
The plasmid often contains genes that give the bacterium some advantage over other bacteria.
Mutations (not seen) may also occur, which may be antibiotic resistant and thus allow the bacteria to survive and reproduce. Some bacteria live in the soil or on dead plant matter where they play an important role in the cycling of nutrients. However, microbial problems associated with reclaimed water may hinder the use of reclaimed water for agricultural irrigation.
For example it may contain a gene that makes the bacterium resistant to a certain antibiotic.
Some types cause food spoilage and crop damage but others are incredibly useful in the production of fermented foods such as yoghurt and soy sauce. Relatively few bacteria are parasites or pathogens that cause disease in animals and plants.
