RESUMO
Rotavirus is one of the leading causes of acute gastroenteritis in infants and young children. RVAs infect not only humans but also a wide range of mammals including rats, which represent a reservoir of several other zoonotic pathogens. Due to the segmented nature of the RVA genome, animal RVA strains can easily adapt to the human host by reassortment with co-infecting human viruses. This study aims to detect and characterize RVA in the intestinal content of Italian sinantropic rats (Rattus rattus). Out of 40 samples examined following molecular approach, one resulted positive for RVA. The molecular characterization of VP1-4, 6 and 7, and NSP1-5 genes by sequencing revealed the genomic constellation G3-P[3]-I1-R11-C11-M10-A22-N18-T14-E18-H13. This uncommon genomic combination includes: the VP1-4,VP7, the NSP1, 3, 4 and 5 gene segments, closely related to those of RVA from rodents, the N18 novel genotype established for the NSP2 gene segment and the human Wa-like VP6 gene, suggesting interspecies reassortment.

Ectoparasitic insects play a major role in veterinary medicine. Fleas infest man and animals and are the most frequent external parasites of companion animals worldwide. Some species are known to be vectors of zoonotic pathogens. Dogs and cats may play an important role either as reservoir of some of the pathogens or as transport vehicles for infected eas between their natural reservoirs and human beings, thus playing a crucial step in the transmission cycle of ea-borne diseases. This article reviews relevant literature on morphology, classi cation, host speci city, geographical distribution, and seasonality of eas infesting dogs and cats in order to improve their timely identi cation, prevention, and control.

In September 2007, a severe cockroach (Blattella germanica) infestation was reported on the premises of the Scutari Regional Hospital. The hospital was infested by cockroaches despite regular insecticide treatment by local pest control officers. The failure of treatment required a careful evaluation of the problem. It also created the opportunity for a more complete analysis of pest control in Albania.
