Preventive Veterinary Medicine Available online 25 September 2015 Sero-surveillance and risk factors for avian influenza and Newcastle disease virus in backyard poultry in Oman. Open Access Highlights We describe the first nationwide survey of the seroprevalence of avian influenza and Newcastle disease viruses in backyard poultry in Oman. The composition of the backyard poultry sector in Oman is described. Both viruses were present in all regions of Oman. The bird-level seroprevalence of both viruses was high (∼40%). The flock-level seroprevalence of both viruses was very high (∼80%). The seroprevalence of AI was highest in turkeys, then chickens and ducks, and lowest in geese and guinea fowl. Significant risk factors were region (both viruses), seroprevalence of AIV (for NDV) and altitude (for AIV).

Suggested citation for this article Abstract To investigate potential transmission of Middle East respiratory syndrome coronavirus (MERS-CoV) to health care workers in a hospital, we serologically tested hospital contacts of the index case-patient in Saudi Arabia, 4 months after his death.
Middle East respiratory syndrome coronavirus (MERS-CoV) was initially isolated in September 2012 from a 60-year-old man from Bisha, Saudi Arabia (1). A zoonotic origin of MERS-CoV has been hypothesized; camels potentially play a role in transmission (7), although the specific types of exposure associated with primary cases remain unknown. Acknowledgments References Table Table. PLOS 24/11/14 Estimating Potential Incidence of MERS-CoV Associated with Hajj Pilgrims to Saudi Arabia, 2014. See all References20 In the Hafr Al-Batin cases reported here, 19.4% among the family contacts tested positive and 2% of the healthcare worker contacts were positive for MERS-CoV (p = 0.0078). See all References3 In the current study, animal contact was reported in 41.7% of all cases.
The presence of animal contact among asymptomatic family contacts further complicate the issue of having secondary cases as a result of direct contact or the result of exposure to the same source or host of MERS-CoV that lead to the index infection. In fact, for family cluster 2, our genetic data indicate that while Patient 8 is likely to have acquired the infection from the index Patient 3, at least two of the infected contacts (Patients 4 and 5) could not have been directly infected from Patient 3 and alternate source should be considered.

EUROSURVEILLANCE 12/12/13 Au sommaire: Middle East Respiratory Syndrome (MERS) coronavirus seroprevalence in domestic livestock in Saudi Arabia, 2010 to 2013. In Saudi Arabia, including regions of Riyadh and Al Ahsa, pseudoparticle neutralisation (ppNT) and microneutralisation (MNT) tests detected no antibodies to Middle East Respiratory Syndrome coronavirus (MERS-CoV) in sheep (n= 100), goats (n= 45), cattle (n= 50) and chickens (n= 240).
Dromedary camels however, had a high prevalence of MERS-CoV antibodies. Bovine coronavirus (BCoV) infected sera from cattle had no cross-reactivity in MERS-CoV ppNT or MNT, while many dromedary camels’ sera reacted to both BCoV and MERS-CoV. Some nevertheless displayed specific serologic reaction profiles to MERS-CoV. In a seroepidemiological study of domestic livestock (sheep, goats, cattle, chicken) and dromedary camels from Saudi Arabia, we find that only dromedary camels have evidence of seropositivity to Middle East Respiratory Syndrome coronavirus (MERS-CoV), suggesting an infection with a MERS-CoV-like virus.

International Journal of Poultry Science - 2007 - Avian Influenza in Nigeria: Suggestions for Eradication. AP 08/02/06 Nigeria reports Africa's frits bird blu outbreak. LAGOS, Nigeria — The deadly H5N1 bird flu virus has been detected on a large commercial chicken farm in Nigeria — the first reported outbreak in Africa, the World Organization for Animal Health said Wednesday. The outbreak appears to be restricted to birds, and no human infections have been reported, the Paris-based organization said. Nigeria said the outbreak was on a farm in Jaji, a village in the northern state of Kaduna. Agriculture Minister Adamu Bello told reporters in Abuja that the deadly strain of the virus was detected in samples taken Jan. 16 from birds on the farm.
“The significance is that it’s a completely new continent that we need to be looking at,” said Alex Thiermann, an expert for the World Organization for Animal Health, known as the OIE, said of the virus’ arrival on the world’s poorest continent. All 46,000 chicken, geese and ostriches on the Nigerian farm have been killed and their bodies disposed of, Thiermann said.
