Survey of Zoonotic Dermatoses in Client‐Owned Exotic Pet Mammals in Southern Italy

Several ‘exotic’ mammalian species (e.g. rabbits, rodents, ferrets and hedgehogs) live in close proximity to humans as companion pets. Skin diseases (SD) are frequent causes of morbidity in exotic pet mammals, and most of those SDs have a zoonotic potential. The purpose of this study was to determine the frequencies and types of zoonotic dermatosis (ZD) in client‐owned, exotic pet mammals in Southern Italy. Six‐hundred and fifty‐five medical records of exotic pet mammals examined between 2011 and 2012, across twenty private practice veterinary clinics around the Naples area (Italy), were retrospectively evaluated and screened for animals diagnosed with SDs (rabbits n = 455, guinea pigs n = 93, ferrets n = 64, hedgehogs n = 19, chinchillas n = 13 and rats n = 11). The records of animals diagnosed with SD, whose causative agents had a zoonotic potential, were selected for analysis. The Mann–Whitney independent test was used for statistical analysis. A P value ≤0.05 was considered statistically significant. Eighty‐two records (12.5%) of animals with ZD were identified. Of those, 56.1% (46/82) were affected by fungal infections and 42.7% (35/82) by parasitic infections. No zoonotic bacterial or viral infections were diagnosed. Dermatophytosis was significantly diagnosed more frequently in younger animals. The results of this survey indicate that exotic pet mammals may serve as active carriers for many highly contagious pathogens with zoonotic potential. Awareness and vigilance by the veterinary practitioner is crucial in the prevention of occurrences of ZDs. Children frequently come in close contact with exotic pets. To prevent the unplanned transmission of pathogen from pet to human, an active routine screening examination and preventative treatments are strongly recommended for every newly purchased pet mammal.     

Hunting vulnerability, ecological characteristics and harvest rates of bushmeat species in afrotropical forests

We reviewed and analysed patterns and between-site variation in hunter-kill profiles of mammals in tropical moist forests in west and central Africa. Published data from 36 sites in seven countries were used. A total of 71 mammals from 8 orders and 22 families were hunted. Significant variation was found in number of species exploited, but ungulates constituted 73.2% of all hunted animals. Rodents and primates contributed 12.2% and 12.0%, respectively. Large-bodied species (15.0-99.9 kg) represented over half (54.4%) of the total hunted biomass. Most species were snared, and were generally medium-sized, fast, terrestrial, frugivore-herbivores. By species, we showed using meta-analysis, that abundance was the main predictor of harvest level. But, the relationship between hunter presence (calculated as average hunter numbers operating per 100 days) and hunter ease (an index of catchability of the hunted fauna) and site harvest levels was shown to be significant only for hunter ease. Site harvest rates were higher in areas with more hunter presence. Overall, an average of 2000 carcasses (16,000 kg in weight) per site was extracted in a year. Per hunter, this amounted to 200 carcasses (1000 kg) extracted. Such amounts fall within reported unsustainable harvest levels of the mammalian fauna in African forests.     

The Structure of the Spermatozoon of Liza Dumerili (Teleostei) With Notes on Spermiogenesis

The structure of the sperm of Liza dumerili was studied by light microscopy and scanning and transmission electron microscopy.

The sperm have a kidney-shaped nucleus. The “hilus” faces posteriorly and the proximal centriole is situated within the nuclear pit. Nuclear rotation takes place during spermiogenesis and the sperm are therefore related to those of other teleosts showing Type I spermiogenesis. No acrosome is evident. The midpiece is small but distinct and contains four spherical mitochondria. The flagellum enters the midpiece eccentrically and the axoneme runs obliquely towards the distal centriole to which it is connected. The flagellum conforms to the 9 + 2 flagellar pattern.

From biology to management of Savi's pine vole (Microtus savii)

Savi's pine vole (Microtus savii) is a rodent species of the Cricetidae family, inhabiting southern European agroecosystems. It is considered to be the main cause of rodent‐attributed damage in Italy. To achieve an effective management, detailed knowledge of this species is needed. However, the available information about this species is fragmentary and incomplete. In this paper, the existing knowledge of Savi's pine vole taxonomy, reproduction, population dynamics, habitat and food preferences is reviewed in order to organise available information and identify priority areas of future research. Some of the changes in farming practices that have occurred in recent decades may have increased the impact of Savi's pine vole populations in crop fields. To manage this pest species effectively, an integrated strategy is recommended (involving habitat management, trapping and, when appropriate, the use of rodenticides). The apparent lack of cyclical population outbreaks and the relatively small litter size and long gestation and interpartum period of this species suggest that it could be more manageable than other vole species, while its strict herbivorous diet, stable population size in open habitats and wide distribution seem to indicate it as an ideal model species for risk assessment studies. © 2015 Society of Chemical Industry
