“…The two U.S. studies found 28% seroprevalence in rural dogs in northern California [58], and 3.9% across the southeast United States [59]. No positive samples were found from regions in Australia and Brazil [60,61,62]. Seroprevalences of 11.2% and 34% were found across Albania and the Galapagos, respectively [63,64].…”

In a world where climate change, vector expansion, human activity, and pathogen dispersal do not respect boundaries, the human–animal–pathogen interface has become less defined. Consequently, a One Health approach to disease surveillance and control has generated much interest across several disciplines. This systematic review evaluates current global research on the use of domestic dogs as sentinels for human infectious disease, and critically appraises how this may be applied within Canada. Results highlighted a bias in research from high- and middle-income-economy countries, with 35% of the studies describing data from the Latin America/Caribbean region, 25% from North America, and 11% from the European/Central Asia region. Bacteria were the most studied type of infectious agent, followed by protozoa, viruses, helminths, and fungi. Only six out of 142 studies described disease in Canada: four researched a variety of pathogens within Indigenous communities, one researched Borrelia burgdorferi in British Columbia, and one researched arboviruses in Quebec. Results from this review suggest that dogs could provide excellent sentinels for certain infectious-disease pathogens in Canada, yet are currently overlooked. Further research into the use of dog-sentinel surveillance is specifically recommended for California serogroup viruses, Chikungunya virus, West Nile virus, Lyme borreliosis, Rickettsia spp., Ehrlichia spp., and Dirofilaria immitis.

Los patógenos transmitidos por vectores, comúnmente conocidos como hemoparásitos, son organismos hemotrópicos que varían desde nematodos, protozoos, virus y bacterias. El presente es un estudio retrospectivo de las bases de datos de 3.300 perros cuyo objetivo es evaluar la frecuencia mediante qPCR para 9 hemotrópicos en la ciudad de Medellín entre junio de 2021 y marzo de 2022 y la correlación de su presencia con las manifestaciones clínicas y hemoleucogramas de 20 perros positivos. Del total de perros testeados, el 60% fueron positivos para uno o más agentes. El número de animales infectados con uno, dos o tres agentes fue del 42,9% (1.416/3.300), 17,7% (583/3.300) y 1,3% (42/3.300), respectivamente. En orden de mayor a menor presencia de hemoparásitos, el número de perros positivos a un solo agente fue de: Anaplasma spp. (14,1%), Mycoplasma spp. (13,9%), Erlichia spp. (6,1%), Hepatozoon spp. (5,4%), Babesia spp. (1%), filarias (0,9%), y Bartonella spp. (0,6%). Las principales alteraciones clínico–patológicas en 9 de 20 perros positivos a algún hemoparásito y con signos clínicos inespecíficos (fiebre, anorexia, mialgia, letargo) fueron de anemia y/o trombocitopenia, con o sin un leucograma inflamatorio. No obstante, la ausencia de alteraciones clínico–patológicas en 11/20 animales positivos no descarta la presencia de infección, ya que los animales presentaban un hemograma normal. Estudios experimentales y de campo han mostrado que muchos perros positivos por serología y/o qPCR están clínicamente normales, y aunque no presentan una infección activa, sí pueden ser portadores asintomáticos de hemoparásitos. En este estudio se discuten los resultados y se comparan.....

Zoonotic-origin infectious diseases are one of the major concerns of human and veterinary health systems. Ticks, as vectors of several zoonotic diseases, are ranked second only to mosquitoes as vectors. Many ticks’ transmitted infections are still endemic in the Americas, Europe, and Africa and represent approximately 17% of their infectious diseases population. Although our scientific capacity to identify and diagnose diseases is increasing, it remains a challenge in the case of tick-borne conditions. For example, in 2017, 160 cases of the Brazilian Spotted Fever (BSF, a tick-borne illness) were confirmed, alarming the notifiable diseases information system. Conversely, Brazilian borreliosis and ehrlichiosis do not require notification. Still, an increasing number of cases in humans and dogs have been reported in southeast and northeastern Brazil. Immunological methods applied to human and dog tick-borne diseases (TBD) show low sensitivity and specificity, cross-reactions, and false IgM positivity. Thus, the diagnosis and management of TBD are hampered by the personal tools and indirect markers used. Therefore, specific and rapid methods urgently need to be developed to diagnose the various types of tick-borne bacterial diseases. This review presents a brief historical perspective on the evolution of serological assays and recent advances in diagnostic tests for TBD (ehrlichiosis, BSF, and borreliosis) in humans and dogs, mainly applied in Brazil. Additionally, this review covers the emerging technologies available in diagnosing TBD, including biosensors, and discusses their potential for future use as gold standards in diagnosing these diseases.
