M. morganii is a gram-negative, non-lactose fermenting and an opportunistic pathogen frequently associated with nosocomial infections. Although first isolated in 1906 from a pediatric fecal sample, not many M. morganii isolates have been sequenced.

This finding was further confirmed genotypically by polymerase chain reaction that showed the presence of efflux genes AcrA, AcrB, TolC and mdtk in these isolates. The ability of metformin to inhibit efflux activity was compared with the reference efflux pump inhibitors verapamil and ascorbic acid. Metformin was more active than ascorbic acid and less active than verapamil. Up to our knowledge, this is the first report that shows that metformin has an efflux pump-inhibiting activity in Klebsiella pneumoniae.

Staphylococcus caprae is an animal-associated bacterium regarded as part of goats’ microflora. Recently, S. caprae has been reported to cause human nosocomial infections such as bacteremia and bone and joint infections. However, the mechanisms responsible for the development of nosocomial infections remain largely unknown. Moreover, the complete genome sequence of S. caprae has not been determined.

The Hafnia genus is an opportunistic pathogen that has been implicated in both nosocomial and community-acquired infections. Although Hafnia is fairly often isolated from clinical material, its taxonomy has remained an unsolved riddle, and the involvement and importance of Hafnia in human disease is also uncertain.

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most predominant agents that cause nosocomial infections. Objectives: To determine the rate of MRSA and the molecular characteristics of the coagulase encoding gene of these isolates based on polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP).

Acinetobacter baumannii has emerged as a highly troublesome pathogen for many institutions globally. As a consequence of its immense ability to acquire or upregulate antibiotic drug resistance determinants, it has justifiably been propelled to the forefront of scientific attention. The clinical specimens over a period of 3 years (January 2014 to December 2016) were analyzed and the A. baumannii isolates obtained by an automated identification system (Vitek 2 Compact) were segregated for further study.

Indoor air contamination of the operating theatres is one of the major sources of life threatening nosocomial infections for patients undergoing certain surgical procedures. There is dearth of information on the burden of airborne microbial contaminations of operating theatres in this environment, hence the need for the study. The study aimed at investigating the airborne microbial load and type of pathogenic isolates as a result of surgical procedures in the operating theatres of a tertiary hospital in South-west Nigeria.

Acinetobacter species has been increasingly reported as the cause of nosocomial infections and possess a serious threat to the health care system because of its multi-drug resistance. The present study was a prospective study carried out in the Department of Microbiology from August 2013 to November 2015 in a tertiary care hospital to isolate and speciate Acinetobacter species from clinical samples and to determine their antibiogram.

Detection of Methicillin resistant strains of Staphylococcus aureus using phenotypic and genotypic methods in a tertiary care hospital Institution: Institute of Microbiology, Madras Medical College. Abstract: Purpose: Methicillin resistant S. aureus (MRSA) are significant pathogens that have emerged over the past 30 years to cause both nosocomial and community acquired infections. This study has been undertaken to compare the conventional and molecular methods in detecting MRSA. S. aureus was isolated from pus samples and identified by Gram stain and Catalase test.

Enterococci mainly being commensals in human faeces are now considered as an important cause of nosocomial infections. Of the infections, the commonly observed are urinary tract infections, abdominal infections followed by bacteremia, endocarditis and meningitis rarely. Speciation of Enterococcus aids in effective management of the infections caused by them. The initial treatment for enterococcal infections has become challenging due to development of resistance. The resistance has been observed mainly against aminoglycosides due to the presence of bi-functional gene.

Coagulase Negative Staphylococci (CONS) are the indigenous flora of the human skin and mucous membrane. They are usually contaminants, when isolated from clinical specimens. CONS have become important nosocomial pathogens, accounting for 9% of all nosocomial infections. These infections are difficult to treat because of the risk factors and the multiple drug resistance of these organisms.

Coagulase-negative staphylococci (CNS) are a main cause of nosocomial infection. The main purpose of this study was to determination of frequency of CNS isolates in in hospitalized patients and their susceptibility pattern to antimicrobial agents. During 11 months study, 147CNS clinical isolates were recovered from hospitalized patients in NMC & hospital Nellore south India. The age of patients was 10 t0 70yrs. In vitro susceptibility of isolates to 14 antimicrobial agents – ampicilin, oxacillin, cefexime. azithromycin, oflaxacin, clindamycin, amikacim, tegycyclin, vancomycin, tegycyclin.

Non-fermenting gram negative bacilli (NFGNB) are a group of aerobic, non spore forming bacilli. They either do not use carbohydrates as a source of energy or degrade them through metabolic pathways other than fermentation. They are ubiquitous in nature. Although they are commonly considered to be environmental contaminants, they have emerged as important nosocomial pathogens. Aim of this study was to characterize the prevalence of NFGNB distribution from various clinical isolates and to evaluate their antibiotic sensitivity patterns.

Candidosis or Candidiasis caused by various species of Candida is the commonest fungal disease found in human beings and is among the four most common causes of nosocomial infections. Antifungal resistance poses a major public health concern. Lack of routine diagnostic testing for fungal diseases exacerbates the problem of antifungal drug empiricism. Aim: To study the Proportion, Speciation and Antifungal Resistance Pattern of the Candida Isolates in a tertiary care hospital of North Kerala. Materials and Methods...

The aim of the study was to speciate the CoNS isolates from various clinical samples and to study their antibiotic susceptibility pattern. Over a period of 18 months from December 2013 to May 2015, 142 Coagulase negative staphylococcal isolates grown in pure culture from various clinical samples were isolated and identified by standard procedure. Speciation of CoNS was done using novobiocin resistance test, urease activity, ornithine decarboxylase, pyrrolidonyl arylamidase and aerobic acid production from mannose.

Methicilin–resistant Staphylococcus aureus (MRSA) is a common cause of serious nosocomial infections with limited options for treatment due to its known resistance to many antibiotics. Knowledge guided antibiotic combination therapy can be of great benefit in fighting this superbug. The aim of this study was to evaluate the combined activity of penicillin G (A) and gentamicin (B) against clinical isolates of methicillin resistant Staphylococcus aureus.
