“…There are 4 clinical case reports documenting B. burgdorferi infection with lympho‐plasmacytic synovitis and lameness in horses . All of the horses in these clinical reports had marked joint or tendon sheath fluid distention, which is not what is commonly reported in the majority of presumed but unconfirmed equine Lyme lameness cases . In a survey of equine practitioners regarding Lyme disease in horses, behavioral changes, hyperesthesia, and muscle wasting were also reported and could be attributed to neuroborreliosis or to lymphocytic‐histiocytic and plasmacytic inflammation of the deep dermis, muscle, and the panniculus .…”

“…Anecdotal reports and a 2009 survey of equine practitioners in the Northeastern United States suggest a plethora of not—well—documented clinical signs associated with Lyme disease in horses, most commonly stiffness and shifting leg or intermittent lameness . There is little research or overt clinical data to document generalized lameness and stiffness as an equine Lyme disease syndrome.…”

Borrelia burgdorferi infection is common in horses living in Lyme endemic areas and the geographic range for exposure is increasing. Morbidity after B. burgdorferi infection in horses is unknown. Documented, naturally occurring syndromes attributed to B. burgdorferi infection in horses include neuroborreliosis, uveitis, and cutaneous pseudolymphoma. Although other clinical signs such as lameness and stiffness are reported in horses, these are often not well documented. Diagnosis of Lyme disease is based on exposure to B. burgdorferi, cytology or histopathology of infected fluid or tissue and antigen detection. Treatment of Lyme disease in horses is similar to treatment of humans or small animals but treatment success might not be the same because of species differences in antimicrobial bioavailability and duration of infection before initiation of treatment. There are no approved equine label Lyme vaccines but there is strong evidence that proper vaccination could prevent infection in horses.

IntroductionHorses (Equus caballus) are susceptible to tick-borne diseases. Two of them, Lyme borreliosis due to Borrelia burgdorferi and granulocytic anaplasmosis due to Anaplasma phagocytophilum were investigated in Algerian horses. The diseases have been less extensively studied in horses and results pertinent to Algeria have not been published.Material and MethodsBlood samples were obtained from 128 horses. IgG antibodies directed against Anaplasma phagocytophilum and Borrelia burgdorferi were detected by an indirect immunofluorescence antibody test (IFAT) and ELISA. The potential effects of age, gender, breed, and health status on seropositivity were also evaluated.ResultsUsing IFAT, 28 (21.8%) and 25 (19.5%) animals were positive for B. burgdorferi and A. phagocytophilum, respectively. Using ELISA, 19 (14.8%) and 33 (25.9%) animals were positive for these bacteria.ConclusionThe study shows that horses in Algeria are exposed or co-exposed to tick-transmitted zoonotic bacterial species.

“…Clinical signs that have been attributed to Lyme borreliosis in horses are typically nonspecific 7 and are believed to result from dissemination of the local infection to other tissues, primarily of connective tissue origin 8 . In horses, borreliosis has been implicated in musculoskeletal, neurological and reproductive disorders 9–12 .…”

Borrelia burgdorferi, the etiologic agent of Lyme disease is a tick born spirochetal infection. Clinical signs of Lyme borreliosis are uncommon in horses, but when present they are often vague and nonspecific. In horses, Lyme borreliosis has been implicated in musculoskeletal, neurological, reproductive, and ocular disorders, including uveitis, but definitive diagnosis can be challenging as the causative agent is rarely isolated and serologic tests can be unreliable and do not confirm active disease. Here, we report two cases of equine uveitis associated with B. burgdorferi based on the identification of spirochetes within ocular fluids and confirmed with PCR testing. The two cases illustrate some of the challenges encountered in the recognition and diagnosis of equine Lyme borreliosis. Although only one of many possible causes of equine uveitis, Lyme disease should be considered a differential diagnosis, especially in endemic areas. Given the possibility for false negative results of serum tests during uveitis associated with B. burgdorferi and the failure of such tests to confirm active infection, a combination of cytologic assessment, antibody, and/or PCR testing of ocular fluids may be worthwhile if the clinical suspicion for Lyme uveitis is high.
