Homeless Perpetrators and Victims of Crimes: Preliminary Findings of a Research in the Region of Puglia (Italy)

The aim of the study is to analyze from a criminological perspective a peculiar case of deviance: that perpetrated by homeless people, defined as "an individuals in a condition of material and immaterial poverty, carrying a complex, dynamic and multiform kind of discomfort".In collaboration with the Division of the Railway Police of the Regions of Puglia, Basilicata and Molise, 95 homeless were recruited and the incidence of perpetrators and victims of crimes was investigated

Produzione, qualità e analisi della filiera produttiva del lino da fibra in Italia

Fibre flax (Linum usitatissimum L.) is disappeared from the ltalian crop systems, while the textile industry has reached a leading position. The reintroduction of the crop is than potentially promising but the crop techniques and the production processes have to be set up. In 12 environments: crop development and growth, cultivar response, straw, fibre and seed yields, and fibre quality were analysed in the 1992-98 period. The data pointed out crop cycles of 176 and 110 d for the autumn and the spring sowing time respectively, corresponding to 1125 and 990°C d cumulated growing degree. Straw yield at pulling was on average of 6.3 t ha-1, with relevant differences among years and environrnents. Early maturity cultivar yielded more in the less favourable sites. N fertilization was occasionally relevant, and a generally distributions of 60 kg N ha-1 was the more effective. In the Mediterranean environments, with the autumn, sowing flax was more productive and the yield steady. The long fibre ratio was often low (10-13%) and the quality uneven because of the insufficient cleanliness due to retting difficulties. Occasionally, the value of the fibre was affected by the insufficient stem length. In the less dense crop, the seed yield was on average 0.9 t ha-1. Such productions were similar to those assessed for the more dense crop. In conclusion: because of the complexity of the interactions among the crop growth, the yield, the retting process and the fibre quality flax reintroduction is doubtful. In the production processes retting seems to be the crucial phase. Il lino da fibra (Linum usitatissimum L.) è da tempo assente negli ordinamenti colturali italiani, mentre è assai importante l'industria di filatura. La reintroduzione della coltura appare quindi potenzialmente promettente, ma richiede la messa a punto dell'agrotecnica e della filiera produttiva. Nel periodo 1992-1998 in 12 ambienti sono stati esaminati: lo sviluppo e la crescita della coltura, l'adattamento di cultivar, la produzione di paglia, fibra e seme, la resa alla stigliatura, la qualità della fibra. I dati raccolti evidenziano cicli colturali in media di 176 e 110 d rispettivamente per le semine autunnali (ambienti del centro-sud) e vemino-primaverili; corrispondenti a somme termiche di 1125 e 990°C d. La produzione di paglia alla estirpatura è stata in media di 6.3 t ha-1 con valori assai variabili tra annate e ambienti. Le varietà a ciclo corto sono apparse migliori nelle condizioni difficili. L'effetto della concimazione azotata è apparsa talvolta rilevante e comunque con dosi ottimali prossime a 60 kg ha-1 di N. Negli ambienti del centro-sud le semine autunnali si sono dimostrate spesso le più interessanti e sicure. La resa in fibra lunga è stata bassa (10-13%) e la qualità variabile per la scarsa pulizia dovuta alle difficoltà di macerazione. La modesta lunghezza tecnica dello stelo sovente riduce il valore del prodotto. In coltura rada, la produzione di seme è variata da 0.5 a 1.5 t ha-1; tali valori non si sono discostati in modo apprezzabile da quelli ottenuti in coltura fitta. In conclusione, la diffusione del lino appare problematica per le complesse interazioni tra la produzione, il processo di macerazione e la qualità della fibra. Soprattutto la macerazione appare il passaggio chiave

Characterization of a catalase-negative methicillin–resistant Staphylococcus aureus isolate from a dog.

A catalase-negative MRSA strain and a methicillin resistant S. pseudintermedius strain (MRSP) were isolated from a dog affected by a severe form of pododermatitis. The catalase negative isolate was typed as a SCCmec I, PVL negative, ST5 t002 strain. A deletion at position 487 of the kat gene altered the functionality of the catalase enzyme. This is the first report of a catalase-negative MRSA in animals. As catalase test is a rapid assay routinely employed for the identification of staphylococci in clinical microbiology laboratories, the presence of MRSA with this uncommon phenotype may be underestimated. Moreover, catalase-negative staphylococci should be investigated more in-depth in order to assess their virulence

SORVEGLIANZA PER EMOPLASMI FELINI IN SUD ITALIA 2007-2011

The prevalence of feline haemoplasma infections in blood samples collected from cats in southern Italy between 2007 and 2011 was evaluated. A convenience-sample of 314 cats (136 healthy; 178 non-healthy;) was screened by polymerase chain reaction using several sets of primers. The overall prevalence of Haemoplasma infections was 18,0% in the samples collection examined in this study. The prevalence was 9,5% for 'Candidatus Mycoplasma haemominutum', 6,5% for Mycoplasma haemofelis and 2% for 'Candidatus Mycoplasma turicensis'. Interestingly, the prevalence was significantly higher in symptomatic (28%) rather than in healthy animals (6%). Also, free-ranging male individuals older than 2 years were more exposed to risks of infection by these pathogens. These findings indicate that haemoplasma infections are common in Italy

Environmental contamination by dog’s faeces: a public health problem?

Abstract The risk to public health from the large number of dog stools present on streets of urban areas is cause for concern. Dog faeces may be a serious hazard because they may contain microorganisms that are both pathogenic to humans and resistant to several classes of antibiotics. The aim of this study was to evaluate the potential for zoonotic infections and for the presence of antibiotic resistant bacteria in canine faeces which contaminates the urban environment. A total of 418 canine faecal samples were collected from streets in seven areas of Bari, Southern Italy. We have isolated multi-drug resistant Enterococci and meticillin-resistant Staphylococcus aureus from these dog faecal samples. The presence of the resistant bacteria in an urban environment may represent a public health hazard which requires control measures by competent authorities. No Salmonella, Yersinia or Campylobacter species were isolated. Giardia cysts were detected in 1.9% of the samples. The predominant Enterococcus species were E. faecium (61.6%), E. gallinarum (23.3%) and E. casseliflavus (5.5%). Other species, including E. faecalis were also isolated. These strains were resistant to clindamycin (86.3%), tetracycline (65.7%), erythromycin (60.27%) and ampicillin (47.9%). High-level aminoglycoside resistance (HLAR) was found in 65.7% of enterococci. Resistance to three or more antibiotics and six or more antibiotics were observed in 67.12% and 38.4% of Enterococcus spp., respectively. Resistance to vancomycin and teicoplanin was not detected in any of the Enterococcus spp. isolated. Methicillin-resistant Staphylococcus aureus was isolated in 0.7% of the faecal samples. Canine faeces left on the streets may represent a risk factor for transmission of microorganisms and a reservoir of multidrug- resistant bacteria thus contributing to the spread of resistance genes into an urban area

Periodontal disease associated with red complex bacteria in dogs

OBJECTIVE: Red complex bacteria (Treponema denticola, Tannerella forsythia and Porphyromonas gingivalis) play a major role in the aetiology of periodontal disease in humans. This study was designed to evaluate the association of such bacteria with periodontal disease in dogs. METHODS: Seventy-three subgingival samples taken from dogs ranging from 2 months to 12 years (median age 4 years) were tested for red complex bacteria using a polymerase chain reaction assay. RESULTS: Thirty-six of 73 (49 · 3%) dogs were found to be positive for T. forsythia and P. gingivalis. Dogs with gingivitis or periodontitis were more likely to be infected with T. forsythia and P. gingivalis [odds ratio (OR) 5 · 4 (confidence interval (CI) 1 · 9-15 · 6), P = 0 · 002] than healthy animals. Only 3 (4 · 1%) of 73 samples were positive for red complex bacteria, but the association with periodontal disease was not significant. Conclusion And Clinical Relevance The results indicate that involvement of red complex bacteria in periodontal disease in dogs is similar to that observed in humans. Only the concurrent presence of T. forsythia and P. gingivalis were correlated to periodontal disease in dogs in this study

Detection of a canine parvovirus type 2c with a non-coding mutation and its implications for molecular characterisation

An epidemiological survey for canine parvovirus (CPV) was conducted by collecting 615 faecal samples from dogs with diarrhoea in different European countries. Molecular methods showed that CPV-2a was predominant in most countries, followed by CPV-2c and CPV-2b, whereas 30 strains were not characterised. By sequence analysis of the full-length VP2 gene, 20 of these viruses were characterised as CPV-2c mutants having the synonymous mutation A4061G in the probe-binding region that prevented correct strain characterisation. A real-time polymerase chain reaction (PCR) assay using a minor groove binder probe was able to recognise both mutant and classical CPV-2c strains. These results indicate that the emergence of CPVs with mutations affecting the oligonucleotide-binding region needs a continuous update of molecular diagnostic tools in order to detect efficiently those emerging strains
