Bacterial zoonoses among domestic reptiles
No full textSUMMARY In the last years an ever-increasing importation of exotic animals destined to live under domestic conditions has been observed. Chelonians, terrestrial and aquatic turtles, are the most commonly present in domestic environment, even if saurians (lizards) and ophidians (snakes) are frequently kept in houses. Reptiles, that can be considered new pet animals, even if clinically healthy, often harbor opportunistic pathogens, which can become cause of serious infections under stress condition. Viral, protozoal, fungal and parasitic agents can infect the cold-blooded animals, but bacteria are the most common pathogens recovered from these animals and in most cases they can be transmitted to humans. Domestic reptiles represent an emerging problem for the public health. New reptile owners should be educated about a proper animal care in order to assure the pet health, to protect themselves from venomous or aggressive species, and to avoid the risk of infection. The main bacterial infections, transmitted from reptiles to humans, are reported, with particular attention to salmonellosis, mycobacteriosis, chlamydophilosis and Aeromonas and Pseudomonas infections. RIASSUNTO Negli ultimi anni si è assistito ad una notevole crescita del numero degli animali esotici destinati a vivere in ambiente domestico. I cheloni, tartarughe di terra e di acqua dolce, sono i più numerosi, ma i sauri e i serpenti sono tenuti come animali domestici con sempre maggiore frequenza. I rettili, anche se clinicamente sani, spesso albergano microrganismi patogeni opportunisti che possono divenire causa di serie patologie durante periodi di stress. Gli animali a sangue freddo sono colpiti da virus, protozoi, funghi, parassiti, ma sono i batteri i microrganismi più frequentemente isolati da soggetti con o senza patologie clinicamente manifeste. Molti di questi batteri sono in grado di causare infezione anche nell’uomo e per questo motivo i rettili domestici devono essere considerati un problema emergente per la sanità pubblica. I nuovi proprietari dovrebbero quindi essere opportunamente educati sui rischi che corrono tenendo i rettili nelle loro case, legati non solo a graffi e morsi talora velenosi, ma anche alle infezioni. Di seguito vengono trattate le principali zoonosi ad eziologia batterica trasmissibili dai rettili all’uomo, con particolare attenzione alle infezioni sostenute da salmonelle, micobatteri, clamidie, Aeromonas e Pseudomonas
Unusual massive beaching of Dalophis imberbis (Delaroche, 1809) (anguilliformes, ophichtidae) from the Central Tyrrhenian Sea
No full textAn unusual massive beaching of about two hundred specimens of the ophichthid eel Dalophis imberbis in the Central Mediterranean Sea was documented with in situ photographs and direct observations of beached specimens. No records of massive beaching of this species are reported in literature and only isolated specimens of D. imberbis were sporadically found beached. This event might be directly related to a severe wintry storm that affected the Latium coast from 2 to 5 March 2017. Some specimens were collected and measured and following laboratory analysis showed that had empty stomachs and no mature reproductive structures despite their large size (Mean TL mm > 400). In this way, further studies are required to determine the causes of this very uncommon event
Antimicrobial properties of terrestrial snail and slug mucus
Full text linkSnail and slug mucus is a viscous-elastic substance secreted by specific glands with adhesive and lubricants properties that allows them to adhere tenaciously to many different surfaces. It has been used since ancient times for care and human health and it is still very important in traditional and folkloristic medicine. Recently, mucus from snail and slugs and its protein and components have been subjected to some investigations on their antibacterial, antiviral and antifungal activity due to extensive traditional uses and for a future application in medicine. Antimicrobial activities of crude mucus, and its components, against different microorganism have been reported, showing antimicrobial activities that lead their potential employment in several fields as natural additives. The purpose of this Review is to summarize the results of antimicrobial studies of snail and slug mucus and its compounds from the first scientific applications to the isolation of the single components in order to better understand its application and propose an employment in future studies as a natural antimicrobial agent

Royal Jelly: An ancient remedy with remarkable antibacterial properties
Full text linkRoyal Jelly (RJ), a honeybee hypopharyngeal gland secretion of young nurse and an exclusive nourishment for bee queen, has been used since ancient times for care and human health and it is still very important in traditional and folkloristic medicine, especially in Asia within the apitherapy. Recently, RJ and its protein and lipid components have been subjected to several investigations on their antimicrobial activity due to extensive traditional uses and for a future application in medicine. Antimicrobial activities of crude Royal Jelly, Royalisin, 10-hydroxy-2-decenoic acid, Jelleines, Major Royal Jelly Proteins against different bacteria have been reported. All these beehive products showed antimicrobial activities that lead their potential employment in several fields as natural additives. RJ and its derived compounds show a highest activity especially against Gram positive bacteria. The purpose of this Review is to summarize the results of antimicrobial studies of Royal Jelly following the timescale of the researches. From the first scientific applications to the isolation of the single components in order to better understand its application in the past years and propose an employment in future studies as a natural antimicrobial agent
