This work has been undertaken to study the occurrence of Clostridium perfringens contamination in the poultry feed ingredients and find out its in-vitro antibiotic sensitivity pattern to various antimicrobial drugs. Two hundred and ninety-eight poultry feed ingredient samples received at Poultry Disease Diagnosis and Surveillance Laboratory, Namakkal, Tamil Nadu in South India were screened for the presence of C. perfringens . The organisms were isolated in Perfringens agar under anaerobic condition and subjected to standard biochemical tests for confirmation...

The pivotal aim of the present context was to isolate diversified group of bacteria from the ruminants and to evaluate their antibiogram pattern against 22 antibiotics of 14 different classes. The bacterial isolates from small and large ruminant (sheep, cattle, and calves) were isolated from the rumen based on various colonies morphology, and subjected for preliminary antibiotics susceptibility assay using disc diffusion method. The most sensitive isolates (based on zone of inhibition) were selected for determining the minimum inhibitory concentration (MIC) of each antibiotic ranging from 1 to 256 μg/mL...

PURPOSE: Recent studies suggest an increasing incidence of gram-negative bacteria and methicillin-resistant Staphylococcus aureus in dacryocystitis. Since patients are often treated empirically without culture data, a changing microbiologic profile will markedly affect the success of oral treatment. To provide current guidelines for the treatment of this common condition, we investigated the microbiology and antibiogram of dacryocystitis seen at our institution. METHODS: The charts of all patients presenting with acute and/or chronic dacryocystitis in University Hospital, Newark, from 2007 to 2015 were reviewed...

In view of the changing antibiotic-resistance profiles of Streptococcus agalactiae from tilapia in China, antimicrobial susceptibilities of 75 S. agalactiae strains were determined by the disc diffusion method, and cluster analyses of the antibiograms and antibiogram types were performed. All strains displayed multidrug resistance (MDR). The antimicrobial-resistance rates were highest (>90%) to aminoglycosides, sulfonamides, pipemidic acid, and norfloxacin, followed by penicillin, ampicillin, and ciprofloxacin (26...

Aim of Study: Respiratory infections account for significant morbidity, mortality and expenses to patients getting admitted to ICU. Antibiotic resistance is a major worldwide concern in ICU, including India. It is important to know the antibiotic prescribing pattern in ICU, organisms and its resistance pattern as there is sparse data on Indian ICUs. Materials and Methods: We conducted a prospective study from August 2015 to February 2016. All patients getting admitted to RICU with respiratory infection who were treated with antibiotics were included into study...

ABSTRACT- 1. The aim of this study was to analyse the association between Escherichia coli isolates recovered from turkeys and the expression of beta-lactamase genes, such as extended spectrum beta lactamase (ESBL) and ampicillin class C (AmpC). The phenotype of the resistance profile was examined using the association between amoxicillin and ceftiofur resistance. 2. Results showed that 84% from the turkey isolates harboured four or five genes associated with the CoIV plasmid. In an antibiogram test, 82% of the isolates were multi-drug resistant (MDR), the highest levels of resistance being against erythromycin (99%) and amoxicillin (76...

Introduction: Coagulase-negative staphylococci (CNS) are normal commensals of human skin and mucous membranes. The objective of the study was to determine the prevalence of CNS among clinical isolates, characterize them up to species level, compare the three conventional methods for detection of biofilm formation, and study their antimicrobial susceptibility pattern. Materials and methods: CNS were obtained from various clinical samples including blood, urine, central venous catheter tips, endotracheal tube aspirate, and pus during a 1-year period (July 1, 2014, to June 30, 2015)...

Background: In intestinal failure (IF) patients receiving home parenteral support (HPS), catheter-related bloodstream infections (CRBSIs) frequently result in replacement of their tunneled central venous catheters (CVCs), which may lead to future loss of central venous access. Objective: This observational study investigated the consequences of a catheter-salvage strategy related to CRBSIs. Design: All CRBSIs from 2002 to 2016 in the Copenhagen IF and microbiological databases were retrospectively analyzed...

OBJECTIVES: Early empiric antibiotic therapy in patients can improve clinical outcomes in Gram-negative bacteraemia. However, the widespread prevalence of antibiotic-resistant pathogens compromises our ability to provide adequate therapy while minimizing use of broad antibiotics. We sought to determine whether readily available electronic medical record data could be used to develop predictive models for decision support in Gram-negative bacteraemia. METHODS: We performed a multi-centre cohort study, in Canada and the USA, of hospitalized patients with Gram-negative bloodstream infection from April 2010 to March 2015...

Twenty-seven microbiological samples were taken from root canals (RC) of the canine teeth of 20 dogs where the pulps were non-vital and exposed due to complicated crown fractures. These pulps were cultured for aerobic/anaerobic bacteria. Antimicrobial susceptibility of isolates was determined using the Kirby-Bauer diffusion test. A total of 49 cultivable isolates, belonging to 27 different microbial species and 18 different genera, were recovered from the 27 RCs sampled. Twenty (40.81 per cent) of the cultivable isolates were Gram positive while 29 (59...

OBJECTIVE: Turicella otitidis is a gram-positive bacillus coryneforme described, after 16S RNA sequencing, in 1994 by Funke et al as a microorganism involved in otitis media, and it is in health conditions a habitual colonizer of the external auditory canal. Since its description, more than twenty years ago, few cases of otitis related to or directly attributed to this microorganism have been published. METHODS: Description of a case of mastoiditis that required surgery and other cases of otic pathology in which T...

Gram negative anaerobic organisms are important pathogens in a range of clinical infections, and susceptibility testing is not commonly performed in the microbiology laboratory. We performed anaerobic susceptibility testing on 70 clinically relevant Gram negative anaerobes isolated from routine cultures in a busy diagnostic laboratory which were identified by MALDI-TOF mass spectrometry (MALDI-TOF MS). The susceptibility testing was performed by two methods: Sensititre trays (ThermoFisher Scientific) against 15 different antibiotics, and Etests (bioMérieux) against five clinically relevant antibiotics (metronidazole, piperacillin-tazobactam, amoxicillin-clavulanate, meropenem and clindamycin)...

The present study was investigating the clinical pictures, prevalence, as well as the ecological conditions associated with Pseudomonas anguilliseptica outbreaks in four cultured seabream (Sparus aurata) farms at different localities in Egypt during the winter season of 2016. The phenotypic and genotypic patterns of pseudomonas isolates were investigated. The existence of intraspecific heterogeneity among different isolates was analyzed using Restriction fragment length polymorphism (RFLP) technique. Attempts on disease control using antibiogram or dietary supplement were also considered...

The clinical practice guidelines on nosocomial pneumonia recommends an empirical regimen that would work in 95% of the patients based on the local antibiogram. The aim of the study was development of an antibiogram for guiding empiric therapy in settings with high prevalence of multi-drug resistant organisms. A retrospective review of electronic health records (e-hospital portal) was done to analyze all respiratory isolates from patients admitted in medical wards and intensive care unit between May 2016 and May 2017...
