Dromedary camels are natural host of the Middle East respiratory syndrome coronavirus (MERS-CoV). However, there are limited studies of MERS-CoV infection of other domestic mammals exposed to infected dromedaries. We expanded our surveillance among camels in Egypt, Tunisia, and Senegal to include other domestic mammalian species in contact with infected camels. A total of 820 sera and 823 nasal swabs from cattle, sheep, goats, donkeys, buffaloes, mules, and horses were collected. Swabs were tested using RT-PCR and virus RNA-positive samples were genetically sequenced and phylogenetically analysed. Sera were screened using virus microneutralization tests and positive sera (where available) were confirmed using plaque reduction neutralization tests (PRNT). We detected 90% PRNT confirmed MERS-CoV antibody in 35 (55.6%) of 63 sera from sheep collected from Senegal, two sheep (1.8%) of 114 in Tunisia and a goat (0.9%) of 107 in Egypt, with titres ranging from 1:80 to ≥1:320. We detected MERS-CoV RNA in swabs from three sheep (1.2%) of 254 and five goats (4.1%) of 121 from Egypt and Senegal, as well as one cow (1.9%) of 53 and three donkeys (7.1%) of 42 from Egypt. Partial sequences of the RT-PCR amplicons confirmed specificity of the results. This study showed that domestic livestock in contact with MERS-CoV infected camels may be at risk of infection. We recommend expanding current MERS-CoV surveillance in animals to include other livestock in close contact with dromedary camels. The segregation of camels from other livestock in farms and live animal markets may need to be considered.

This report presents the results of surveillance on transmissible spongiform encephalopathies (TSEs) in bovine animals, sheep, goats, cervids and other animal species, as well as genotyping in sheep, carried out in 2017 in the European Union (EU) according to Regulation (EC) 999/2001, and in Iceland, Norway and Switzerland. In total, 1,312,714 cattle were tested by the 28 EU Member States (MSs) which is a decrease of 3% compared with 2016; 18,526 were tested by the three non‐MSs. For the first time since bovine spongiform encephalopathy (BSE) has been reported, no cases of classical BSE were reported in 2017. Six atypical BSE cases were reported by three different MSs: Spain 1 H‐BSE/2 L‐BSE; France 1 H‐BSE/1 L‐BSE; and Ireland 1 L‐BSE. Over the year, 314,547 sheep and 117,268 goats were tested in the EU. In sheep, 933 cases of scrapie were reported: 839 classical and unknown (145 index cases) by eight MSs and 94 atypical (89 index cases) by 13 MSs. Fourteen ovine scrapie cases were reported by Iceland and Norway. Of all classical scrapie cases, 98.2% occurred in sheep with genotypes of susceptible groups. The genotyping of a random sample in 21 MSs showed that 26.5% of the genotyped sheep carried genotypes of the susceptible groups. In goats 567 cases of scrapie were reported: 558 classical (42 index cases) by seven MSs and nine atypical (seven index cases) by five MSs. In total, 3,585 cervids were tested for TSE by ten MSs, mostly by Romania. All results were negative. Eleven cases of chronic wasting disease (CWD) cases were reported in cervids by Norway: nine wild reindeer, one moose and, for the first time ever, one red deer. In total, 185 animals from five species other than cattle, small ruminants and cervids were tested by three MSs, with negative results.

Molecular tests revealed influenza D viruses of D/OK lineage widely circulating in farmed animal species in Guangdong Province, southern China. In particular, we found high levels of influenza D virus infection in goats and pigs. We also detected viral RNA in serum specimens and feces of animals with certain severe diseases.

The Middle East respiratory syndrome coronavirus (MERS-CoV) was first recognized in 2012 and can cause severe disease in infected humans. Dromedary camels are the reservoir for the virus, although, other than nasal discharge, these animals do not display any overt clinical disease. Data from in vitro experiments suggest that other livestock such as sheep, goats, and horses might also contribute to viral transmission, although field data has not identified any seropositive animals. In order to understand if these animals could be infected, we challenged young goats and horses and adult sheep with MERS-CoV by intranasal inoculation. Minimal or no virus shedding was detected in all of the animals. During the four weeks following inoculation, neutralizing antibodies were detected in the young goats, but not in sheep or horses.
