Fig. 1. A global picture of S. equi diversity visualized in Microreact. Coloured circles indicate the country from which the isolates originated, as illustrated in the key. (a) World map depicting the country of origin of the 670 S. equi isolates. (b) Midpoint-rooted phylogenetic reconstruction of the S. equi population. The dendrogram was reconstructed from pairwise cgMLST scores using the ape package [25]. The resulting tree was midpoint rooted using the phangorn package [26]. The scale bar relates to horizontal branch lengths and indicates the number of cgSNPs that are proposed to have occurred on the vertical branches. The six genetically distinct BAPS clusters and six multilocus STs are indicated on the coloured metadata bars and associated key. (c) Timeline of the collection from 1955 to 2017.

The equine disease strangles, which is characterized by the formation of abscesses in the lymph nodes of the head and neck, is one of the most frequently diagnosed infectious diseases of horses around the world. The causal agent, Streptococcus equi subspecies equi , establishes a persistent infection in approximately 10 % of animals that recover from the acute disease. Such ‘carrier’ animals appear healthy and are rarely identified during routine veterinary examinations pre-purchase or transit, but can transmit S. equi to naïve animals initiating new episodes of disease. Here, we report the analysis and visualization of phylogenomic and epidemiological data for 670 isolates of S. equi recovered from 19 different countries using a new core-genome multilocus sequence typing (cgMLST) web bioresource. Genetic relationships among all 670 S. equi isolates were determined at high resolution, revealing national and international transmission events that drive this endemic disease in horse populations throughout the world. Our data argue for the recognition of the international importance of strangles by the Office International des Épizooties to highlight the health, welfare and economic cost of this disease. The Pathogenwatch cgMLST web bioresource described herein is available for tailored genomic analysis of populations of S. equi and its close relative S. equi subspecies zooepidemicus that are recovered from horses and other animals, including humans, throughout the world. This article contains data hosted by Microreact .

... A separate genetic clade of C buteonis was also recently identified in 39 gyrfalcons (Falco rusticolus) from the United Arab Emirates, demonstrating new clades and that genotype classification of C buteonis is still in its infancy. 32 Because many cases were tested before C buteonis-specific primers or sequencing were available, we cannot say with confidence that all cases are truly C buteonis. ...

... Ethiopia has no animal welfare legislation and donkeys have been of little concern to veterinary authorities. Health and welfare challenges facing working donkeys and mules in Ethiopia include relationship and management problems such as poor communication and handling; poor nutrition; poor harnessing practice resulting in wounds, sores, and injuries; hoof associated problems and other causes of lameness; road traffic accidents, neglect and abandonment; and diseases such as tetanus, strangles, rabies, parasites, epizootic lymphangitis and colic (Yilma et al., 1990;Endebu and Roger, 2003;Curran et al., 2005;Biffa and Woldemeskel, 2006;Mekuria et al., 2013;Getachew et al., 2014;Chala et al., 2019;Meseret et al., 2014). ...

... Mammalian hosts can also appear asymptomatic for long periods of time 1 and potentially spread the infection to other animals. Considering the large economic impact that T. evansi has in various agriculture-oriented countries, preventive strategies to control its spread have been severely lacking 8,18,19 . Not much is known about the full situation of Surra in the UAE as it seems likely that a considerable amount of cases are under reported. ...

... Genomic analyses have demonstrated that S. equi exhibits a low level of diversity relative to its global distribution [10][11][12], which is problematic when it comes to partitioning the population for analysis and epidemiological investigations. Multilocus sequence typing (MLST) provides poor resolution for S. equi. ...

... It has been later reported in the U.S. and many European countries [47,48]. T. asinigenitalis used to be considered as non-pathogenic, but recently a new strain of T. asinigenitalis isolated from a wild jack was reported to cause severe, purulent endometritis in mares [49]. On the other hand, T. asinigenitalis does not apparently cause natural diseases in jennies or jacks [50]. ...

... In addition, the Luminex assay, originally developed for the diagnosis of equine glanders, was performed as previously described using the heat shock protein (GroEL) (BPSL2697) and hemolysin-coregulated protein (Hcp1) (BPSS1498) antigens [32]. A serum from a horse naturally infected with B. mallei (identified as MRI#1) was used as a positive control to determine S/P%, which was calculated for each antigen using the same formula as for GLANDA ELISA. ...

... The observation of a camel-calf pair with a shared nasal GBS type suggest nose to nose contact may be a route of transmission. Reports of GBS in respiratory tract infections in camels suggest that the nasal cavity may serve as a reservoir for opportunistic GBS infections [13,42]. In humans, rectal colonisation is the most common form of GBS carriage and widely recognized as a source of sporadic disease in infants [43]. ...
