During October of 1984 an influenza epidemic occurred on mink farms in the coastal region of South Sweden. Six strains of an influenza A virus were isolated. All six isolates were of the H 10 subtype in combination with N4. The H 10 subtype in combination with various N subtypes was hitherto only known to occur in avian strains, the prototype being the A/chicken/Germany/N/49 (H 10N7) virus.
To investigate the role of Swedish dogs as potential reservoirs of thermophilic Campylobacter species, faecal samples were analysed from 91 dogs in 2001. The majority of dogs (n = 84) were healthy family dogs. Campylobacter spp. were isolated from 51 of the 91 dogs (56%). A significant difference in isolation rates was observed between younger and older dogs: 76% of the younger dogs (5-12 months) were positive, compared with 39% of dogs > or = 13 months (p < 0.01). Two different selective media, Preston and CAT, were used for isolation of Campylobacter species. 104 Campylobacter isolates were identified to species level using polymerase chain reaction and restriction enzyme analysis techniques. Campylobacter upsaliensis predominated and was isolated from 39 dogs, C. jejuni from 10, C. coli from 2, C. helveticus from 2 and C. lari from 1 dog. Four dogs had mixed flora with 2 different Campylobacter species. These data clearly show that younger dogs in particular frequently shed thermophilic Campylobacter spp, which could be of impact for public health. To establish the zoonotic potential of canine Campylobacter isolates, both human and canine isolates have to be further characterized and compared.
The elimination of rabies transmitted by Classical Rabies Virus (RABV) in the European Union (EU) is now in sight. Scientific advances have made it possible to develop oral vaccination for wildlife by incorporating rabies vaccines in baits for foxes. At the start of the 1980s, aerial distribution of vaccine baits was tested and found to be a promising tool. The EU identified rabies elimination as a priority, and provided considerable financial and technical resources to the infected EU Member States, allowing regular and large-scale rabies eradication programs based on aerial vaccination. The EU also provides support to non-EU countries in its eastern and south eastern borders. The key elements of the rabies eradication programs are oral rabies vaccination (ORV), quality control of vaccines and control of their distribution, rabies surveillance and monitoring of the vaccination effectiveness. EU Member States and non-EU countries with EU funded eradication programs counted on the technical support of the rabies subgroup of the Task Force for monitoring disease eradication and of the EU Reference Laboratory (EURL) for rabies. In 2018, eight rabies cases induced by classical rabies virus RABV (six in wild animals and two in domestic animals) were detected in three EU Member States, representing a sharp decrease compared to the situation in 2010, where there were more than 1500 cases in nine EU Member States. The goal is to reach zero cases in wildlife and domestic animals in the EU by 2020, a target that now seems achievable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
