Molecular Epidemiology of Foot-and-Mouth Disease Viruses in the Emirate of Abu Dhabi, United Arab Emirates. Vet Sci 2024; 11:32. [PMID: 38250938 PMCID: PMC11154577 DOI: 10.3390/vetsci11010032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 01/04/2024] [Accepted: 01/06/2024] [Indexed: 01/23/2024] Open
Abstract
Foot-and-mouth disease (FMD) is an endemic disease in the United Arab Emirates (UAE) in both wild and domestic animals. Despite this, no systematic FMD outbreak investigation accompanied by molecular characterisation of FMD viruses (FMDVs) in small ruminants or cattle has been performed, and only a single report that describes sequences for FMDVs in wildlife from the Emirate has been published. In this study, FMD outbreaks that occurred in 2021 in five animal farms and one animal market in the Emirate of Abu Dhabi were investigated. Cases involved sheep, goats, and cattle, as well as Arabian oryx (Oryx leucoryx). Twelve samples were positive for FMDV via RT-qPCR, and four samples (Arabian oryx n = 1, goat n = 2, and sheep n = 1) were successfully genotyped using VP1 nucleotide sequencing. These sequences shared 88~98% identity and were classified within the serotype O, Middle East-South Asia topotype (O/ME-SA). Phylogenetic analysis revealed that the Arabian oryx isolate (UAE/2/2021) belonged to the PanAsia-2 lineage, the ANT-10 sublineage, and was closely related to the FMDVs recently detected in neighbouring countries. The FMDV isolates from goats (UAE/10/2021 and UAE/11/2021) and from sheep (UAE/14/2021) formed a monophyletic cluster within the SA-2018 lineage that contained viruses from Bangladesh, India, and Sri Lanka. This is the first study describing the circulation of the FMDV O/ME-SA/SA-2018 sublineage in the UAE. These data shed light on the epidemiology of FMD in the UAE and motivate further systematic epidemiological studies and genomic sequencing to enhance the ongoing national animal health FMD control plan.

Aslam M, Alkheraije KA. The prevalence of foot-and-mouth disease in Asia. Front Vet Sci 2023; 10:1201578. [PMID: 37456961 PMCID: PMC10347409 DOI: 10.3389/fvets.2023.1201578] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 06/07/2023] [Indexed: 07/18/2023] Open
Abstract
Foot-and-mouth disease (FMD) is listed among the highly contagious diseases in animals and is endemic throughout the Asian continent. The disease is caused by the Foot-and-mouth disease virus (FMDV) and affects a wide variety of domesticated animals as well as wild ungulates. Clinically, the disease is described as a vesicular lesion on the tongue, muzzle, lips, gum, dental pad, interdigital cleft, coronary band, and heel of the foot. Sometimes these lesions give rise to lameness. Mastitis is also caused due to teat lesions. A biochemical test reveals that during FMD infection, there are elevated levels of interleukin-1 (IL-1), tumor necrosis factor-alpha, interferon-gamma (IFN-γ), interleukin-6, serum amyloid A protein, lactoferrin, mannose-binding lectin, and monocytes chemo-attractant protein-1 in the serum of infected animals. There is no specific treatment for FMD although some antivirals are given as prophylaxis and antibiotics are given to prevent secondary bacterial infection. This review presents comprehensive data on the prevalence of FMD and serotypes of FMDV that are attributable to the cause of FMD from a regional point of view. It also explains the worldwide dynamics of the seven serotypes of FMD and tries to identify epidemiological clusters of FMD in various geographical areas. Furthermore, the pathology associated with the foot and mouth disease virus along with the pathophysiology is discussed. The continent-wide prevalence and diversity patterns of FMD suggest that there is a need for stringent policies and legislation implementation regarding research and development aimed at manufacturing strain-specific vaccination, infection prevention, and control of the disease.

FMD virus spillover from domestic livestock caused outbreak in captive wild ungulates: First report from Pakistan. Acta Trop 2022; 231:106439. [PMID: 35378060 DOI: 10.1016/j.actatropica.2022.106439] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Revised: 03/26/2022] [Accepted: 03/30/2022] [Indexed: 11/21/2022]
Abstract
The potential spillover of foot and mouth disease (FMD) virus at the wildlife-livestock interface is mainly responsible for the outbreaks in captive wild ungulates. The current study was planned to investigate an FMD outbreak in the wild ungulate species in the Jallo Wildlife Park and breeding facility, Lahore, Pakistan from Mar 2021- Jun 2021. The disease was confirmed based on ELISA through the detection of antibodies against the non-structural protein of FMD virus and typical clinical signs of oral and feet lesions, and even partial or complete hoof shedding in severe cases. To investigate the possible cause of FMD spillover and its pattern, a series of interviews were conducted with wildlife practitioners, animal handlers, and the local veterinarians in villages adjacent to the park. The data revealed neither vaccination nor any FMD outbreak in the last 10 years. The epidemic curve and time-series analysis showed a mixed outbreak characterized by the introduction of disease and then propagative spread from infected to susceptible animals. After the first reports of clinical signs in Blackbuck, Urial and Mouflon sheep were infected while in the end, the cases were reported from the enclosures of Sambar deer and Spotted deer. The morbidity rate among all the wild ungulate species was 92% and the mean mortality rate was 27%. The study concluded that possible sources for primary disease incidence might be animal handlers having FMD infected animals in their houses and transport vehicles coming from adjacent disease-affected villages. For the disease spread between enclosures, another possibility of wind-borne FMD virus spread could also be considered. This is the first report regarding the FMD outbreak and its spillover pattern in captive wild ungulates in Pakistan. These findings will be helpful in understanding the importance of wildlife livestock interface in FMD transmission and to design effective strategies to control the disease.

Orbivirus Screening from Imported Captive Oryx in the United Arab Emirates Stresses the Importance of Pre-Import and Transit Measures. Pathogens 2022; 11:pathogens11060697. [PMID: 35745551 PMCID: PMC9229846 DOI: 10.3390/pathogens11060697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/13/2022] [Accepted: 06/14/2022] [Indexed: 02/01/2023] Open
Abstract
From 1975 to 2021, the United Arab Emirates (UAE) imported more than 1300 live Arabian oryxes (AOs) and scimitar-horned oryxes (SHOs) for conservation programs. The objective of this study was to estimate the prevalence of orbiviruses Bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) in AOs and SHOs from captive herds in the UAE. Between October 2014 and April 2015, 16 AOs and 13 SHOs originating from Texas (USA) and 195 out of about 4000 SHOs from two locations in the UAE were blood sampled to be tested by indirect enzyme-linked immunosorbent assay (ELISA) and real-time reverse transcriptase polymerase chain reaction (RT-qPCR) assays. Eight imported AOs (50% CI [24.7–75.4%]) and eight imported SHOs (61.5% CI [31.6–86.1%]) were found BTV seropositive, in contrast with three out of 195 SHOs (1.5% CI [0.3–4.4%]) from the Emirates. BTV-2 genome was detected in 6/16 of the Arabian Oryx, and amongst those, one out of six was seronegative. None of the tested samples was found positive for EHDV. Our results illustrate the wide local variation regarding BTV seroprevalence in domestic and wild ruminants in the Arabian Peninsula. These results stress the need for pre-import risk assessment when considering translocation of wild ruminant species susceptible to orbiviruses not only in the country of destination but also where transit happens.

Abstract
The ongoing mass extinction of animal species at an unprecedented rate is largely caused by human activities. Progressive habitat destruction and fragmentation is resulting in accelerated loss of biodiversity on a global scale. Over decades, captive breeding programs of non-domestic species were characterized by efforts to optimize species-specific husbandry, to increase studbook-based animal exchange, and to improve enclosure designs. To counter the ongoing dramatic loss of biodiversity, new approaches are warranted. Recently, new ideas, particularly the application of assisted reproduction technologies (ART), have been incorporated into classical zoo breeding programs. These technologies include semen and oocyte collection, artificial insemination, and in-vitro embryo generation. More futuristic ideas of advanced ART (aART) implement recent advances in biotechnology and stem-cell related approaches such as cloning, inner cell mass transfer (ICM), and the stem-cell-associated techniques (SCAT) for the generation of gametes and ultimately embryos of highly endangered species, such as the northern white rhinoceros (Ceratotherium simum cottoni) of which only two female individuals are left. Both, ART and aART greatly depend on and benefit from the rapidly evolving cryopreservation techniques and biobanking not only of genetic, but also of viable cellular materials suitable for the generation of induced pluripotent stem cells (iPSC). The availability of cryopreserved materials bridges gaps in time and space, thereby optimizing the available genetic variability and enhancing the chance to restore viable populations.

Foot and mouth disease in a wide range of wild hosts: a potential constraint in disease control efforts worldwide particularly in disease-endemic settings. Acta Trop 2020; 210:105567. [PMID: 32504589 DOI: 10.1016/j.actatropica.2020.105567] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 05/29/2020] [Accepted: 05/29/2020] [Indexed: 11/19/2022]
Abstract
Foot and mouth disease (FMD) is a viral disease that affects predominantly cloven-footed animal species within the order Artiodactyla. The potential of the virus to transmit, maintain and circulate itself across a wide range of susceptible hosts, including both domestic and wild ungulates, remains a single major obstacle in an effective eradication of disease worldwide, particularly in disease-endemic settings. Hence, a better understanding of virus transmission dynamics is very much crucial for an efficient control of the disease, particularly at places or regions where wildlife and livestock rearing co-exists. Both OIE and FAO have jointly launched the FMD-control program as FMD-Progressive Control Pathway (PCP) in various disease-endemic developing countries. Nevertheless, the propensity of virus to inter- and intra-species transmission may be a possible constraint in disease control and, hence, its subsequent eradication in such countries. Other than this, cross-species transmission, among domestic and wild ungulates living in close proximities, can undermine the conservation efforts for endangered species. We reviewed and summarized the so-far available information about inter- and intra-species disease transmission, and its impact on wildlife populations to better comprehend disease epidemiology and substantiate efforts for eventual disease eradication across the globe, particularly in settings where the disease is endemic.
