First Report of as an Emerging Bacterial Pathogen of Farmed Nile Tilapia () in Brazil.

Brazil is one of the world's leading producers of Nile tilapia, . However, the industry faces a major challenge in terms of infectious diseases, as at least five new pathogens have been formally described in the last five years. species are Gram-negative anaerobic bacteria that are often described as fish pathogens causing Motile Aeromonas Septicemia (MAS).

The rise of multidrug resistant Salmonella isolates in healthy chickens in Brazil by successful establishment of plasmid IncHI2A carrying several antibiotic resistance genes.

Salmonella spp. is an important global issue in food-producing animals. The present study evaluated antimicrobial resistance and virulence profiles in Salmonella spp.

The plasmidome of multidrug-resistant emergent Salmonella serovars isolated from poultry.

The rapid emergence of resistant bacteria is occurring worldwide. The understanding of the dissemination of antimicrobial resistance using high-throughput sequencing and bioinformatics approaches is providing valuable insights into the genetic basis of the horizontal gene transfer and the emergence of the antibiotic resistance threat. This ultimately can offer vital clues to the development of coordinated efforts to implement new policies to continue fighting against bacterial infections.

Extensively drug-resistant IMP-16-producing Pseudomonas monteilii isolated from cerebrospinal fluid.

IMP-1-producing Pseudomonas aeruginosa was first reported in Japan and since then, bacteria with this metallo-β-lactamase have been detected worldwide. Pseudomonas monteilii (part of P. putida group) were considered an environmental pathogen with low virulence potential; however, multidrug-resistant and carbapenem-resistant P.

Antibiotic resistance and heavy metal tolerance plasmids: the antimicrobial bulletproof properties of isolated from poultry.

We describe the mobilome of 40A isolated from poultry, consisting of four different plasmids, p46_40A (IncX1, 45,869 bp), p80_40A (non-typable, 79,635 bp), p150_40A (IncI1-ST1, 148,340 bp) and p280_40A (IncHI2A-ST2, 279,537 bp). The mobilome-40A carries a blend of several different resistance and virulence genes, heavy metal tolerance operons and conjugation system. This mobilome 40A is a perfect tool to preserve and disseminate antimicrobial resistance and makes the bacterial isolate incredibly adapted to survive under constant antimicrobial pressure.

A Phage-Like Plasmid Carrying Gene in Carbapenem-Resistant .

Lateral gene transfer plays a central role in the dissemination of carbapenem resistance in bacterial pathogens associated with nosocomial infections, mainly and . Despite their clinical significance, there is little information regarding the mobile genetic elements and mechanism of acquisition and propagation of lateral genes in , and they remain largely unknown. The present study characterized the genetic context of in carbapenem-resistant strain BH9.

SPM-1-producing Pseudomonas aeruginosa ST277 carries a chromosomal pack of acquired resistance genes: An example of high-risk clone associated with 'intrinsic resistome'.

Objectives: The purpose of this study was to investigate the resistome of an SPM-1-producing Pseudomonas aeruginosa ST277 isolate (HC84) from Brazil.

Methods: Whole-genome sequencing of P. aeruginosa HC84 was performed using an Ion Proton™ System.

Adaptation of Pseudomonas aeruginosa to the chronic phenotype by mutations in the algTmucABD operon in isolates from Brazilian cystic fibrosis patients.

Chronic lung infection by Pseudomonas aeruginosa is the leading cause of morbidity and mortality in cystic fibrosis (CF) patients. This is associated with the conversion of the non-mucoid to the mucoid phenotype. However, there is little information about the occurrence of alginate-producing P.

New Small Plasmid Harboring blaKPC-2 in Pseudomonas aeruginosa.

The aim of this study was to characterize the genetic context of blaKPC-2 in Pseudomonas aeruginosa sequence type 244 from Brazil. The blaKPC-2 gene was detected in a new small plasmid, pBH6. Complete sequencing revealed that pBH6 was 3,652 bp long and included the Tn3 resolvase and Tn3 inverted repeat (IR), a partial copy of ISKpn6, and a putative ori region but no rep genes.

Radiotherapy does not impair dentin adhesive properties in head and neck cancer patients.

Objectives: This study evaluated the influence of radiotherapy on the dentin bond strength of teeth extracted from patients who had undergone head and neck radiotherapy.

Materials And Methods: A total of 36 samples were divided into two experimental groups: group I (control group, n = 18) and group II (in vivo irradiated group, n = 18). Groups I and II were further separated into three subgroups (six specimens per subgroup), which were further assigned to the three adhesive system protocols employed: Single Bond 2 (SB) (3M ESPE), Easy Bond (EB) (3M ESPE) and Clearfil SE Bond (CSE) (Kuraray).

Isolation of NDM-1-producing Pseudomonas aeruginosa sequence type ST235 from a stem cell transplant patient in Italy, May 2013.

We describe the first isolation of an NDM-1-producing Pseudomonas aeruginosa in Italy. In May 2013, a patient with acute lymphoblastic leukaemia and history of prior hospitalisation in Belgrad, Serbia, underwent stem cell transplantation at a tertiary care hospital in Rome, Italy. After transplantion, sepsis by NDM-1-producing P.

[In vitro study of periodontal ligament cells].

Background: The aim of this research is to outline a procedure able to promote specific cellular differentiation and proliferation with consequent periodontal regeneration. To achieve this goal, use was made of various compounds supposed to have the capacity of aiding periodontal regeneration.

Methods: The cells utilised for this study were obtained from explants of human periodontal ligaments.

A comparative study of a surgical method and scaling and root planing using the Odontoson.

This investigation compared a traditional periodontal surgical method with a non-surgical treatment of scaling and root planing by an ultrasonic device (Odontoson M) using irrigation with an iodised solution. 8 adult patients with periodontal disease were each treated at 2 randomly chosen quadrants by a Widman flap type surgical technique, and the remaining non-surgically. The patients then attended bi-monthly oral hygiene sessions over a period of 1 year.

Prognostic significance of nucleolar organizer regions in recurrent pleomorphic adenomas of salivary glands.

Pleomorphic adenoma (PA) is the commonest tumor of salivary glands. It is considered a benign tumor which may recur and rarely metastatize. There are no reliable histological criteria for predicting recurrences of PA.

Salivary gland tumors: revision of 391 cases according to the new WHO classification.

We reviewed 391 cases of salivary gland tumors collected in a 13 year period at the Institute of Pathological Anatomy of the University of Modena, according to the new WHO classification (1991). A diagnosis of pleomorphic adenoma was changed in adenoid cystic carcinoma. Within malignant tumors, 16 cases were reclassified, and new entities, such as polymorphous low-grade adenocarcinoma, papillary cystoadenocarcinoma and salivary duct carcinoma were introduced.

[Considerations concerning respiratory physiopathology in a case of total arhinia].

The Authors describe their personal experience in a rare case of total arhinia in a young boy, now seven years old, whose psycho-physical development is normal and who is healthy except for recurrent conjunctivitis due to the absence of nasolacrimal ducts. The Authors consider the possibility that in the case of total absence of the nasal function, as in total arhinia, the oropharyngeal and laryngotracheobronchial mucosa may acquire those functional and defensive properties typically belonging to nasal mucosa. In the subject in question, in fact, functional respiratory and immunosecretory parameters are normal.

Turbinoplasty: personal technique and long-term results.

An original conservative technique for surgical reduction of the inferior turbinates, called turbinoplasty, is described. We analyzed, in 308 cases, the functional objective and subjective outcome of turbinoplasty itself and in comparison with more destructive procedures called turbinotomies. The results show that both procedures (in skilled hands!) are good.

[The therapy of cervical adenopathies in tumors of the lip and oropharynx].

The authors, after some notes of topographic anatomy about the lymph nodes of the cervical area, examine the different therapeutic managements of lymph node metastasis of lip and oropharynx carcinoma. From these data, the authors put in evidence that almost all the surgeons and the radiotherapists do agree about the inclusion of radiotherapy, polychemotherapy and, more often, surgery in the treatment of cervical lymph node metastasis. The authors experience suggests no treatment of the cervical region in case of N0 lower lip cancer, especially if the neck is thin, and easy to examine, but it is necessary a careful follow-up in order to discover as soon as possible a clinic metastasis.

[Pre- and post-operative information for the laryngectomized patient: verification of the validity of a brochure].

For those patients who are candidates for total laryngectomy, therapy is not terminated upon surgery and subsequent speech therapy. Treatment must, instead, take into consideration numerous, important psychological problems which arise upon learning the diagnosis and the need for radical surgery. Therefore, all those who come into contact with the patient during the different phases of disease (i.
