“…The present work is the longest-term (17 years) epidemiological surveillance study of B. burgdorferi ever performed in Spain. The seroprevalence of 13.3% detected in the present work falls within the range previously reported for Spain (0.3–14.8%) and other European countries (1.8%–19.68%) [24,25,26,27,28,29]. …”

This paper reports a 17-year seroepidemiological surveillance study of Borrelia burgdorferi infection, performed with the aim of improving our knowledge of the epidemiology of this pathogen. Serum samples (1,179) from patients (623, stratified with respect to age, sex, season, area of residence and occupation) bitten by ticks in two regions of northern Spain were IFA-tested for B. burgdorferi antibodies. Positive results were confirmed by western blotting. Antibodies specific for B. burgdorferi were found in 13.3% of the patients; 7.8% were IgM positive, 9.6% were IgG positive, and 4.33% were both IgM and IgG positive. Five species of ticks were identified in the seropositive patients: Dermacentor marginatus (41.17% of such patients) Dermacentor reticulatus (11.76%), Rhiphicephalus sanguineus (17.64%), Rhiphicephalus turanicus (5.88%) and Ixodes ricinus (23.52%). B. burgdorferi DNA was sought by PCR in ticks when available. One tick, a D. reticulatus male, was found carrying the pathogen. The seroprevalence found was similar to the previously demonstrated in similar studies in Spain and other European countries.

“…However, B burgorferi was found to have a low prevalence in dogs in central Spain and in people in northeast Spain. 26,27 The commercial kit utilised here is known to detect B burgdorferi antibodies in cats, 1 and so the result is likely a true positive. However, the kitten was young and so the positive test likely reflects maternal antibodies from the queen.…”

ObjectivesThe objective of the current study was to investigate the prevalence rates of the following infectious agents in 116 stray cats in the Barcelona area of Spain: Anaplasma phagocytophilum, Bartonella species, Borrelia burgdorferi, Chlamydia felis, Dirofilaria immitis, Ehrlichia species, feline calicivirus (FCV), feline herpesvirus-1 (FHV-1), feline leukaemia virus (FeLV), feline immunodeficiency virus (FIV), haemoplasmas, Mycoplasma species and Rickettsia species.MethodsSerum antibodies were used to estimate the prevalence of exposure to A phagocytophilum, Bartonella species, B burgdorferi, Ehrlichia species and FIV; serum antigens were used to assess for infection by D immitis and FeLV; and molecular assays were used to amplify nucleic acids of Anaplasma species, Bartonella species, C felis, D immitis, Ehrlichia species, FCV, FHV-1, haemoplasmas, Mycoplasma species and Rickettsia species from blood and nasal or oral swabs.ResultsOf the 116 cats, 63 (54.3%) had evidence of infection by Bartonella species, FeLV, FIV or a haemoplasma. Anaplasma species, Ehrlichia species or Rickettsia species DNA was not amplified from these cats. A total of 18/116 cats (15.5%) were positive for FCV RNA (six cats), Mycoplasma species DNA (six cats), FHV-1 DNA (three cats) or C felis DNA (three cats).Conclusions and relevanceThis study documents that shelter cats in Catalonia are exposed to many infectious agents with clinical and zoonotic significance, and that flea control is indicated for cats in the region.

“…El porcentaje de seropositivos obtenido por los médicos de los CAP fue superior al hallado por los profesionales de otros CAP en Navarra (4,4%) 10 o en Castilla y León (13,3%) 3 . No obstante, la seropositividad observada en los CAP resultó ligeramente más baja que la señalada en un estudio realizado en diversos centros de salud de Polonia (27-29%) 7 .…”

“…Al igual que en nuestro estudio, otros autores señalan que la seropositividad a Borrelia es más baja en los residentes en zonas urbanas que en los del medio rural3, 4, ya que estos últimos se dedican fundamentalmente a labores agrícolas y ganaderas que les obligan a un mayor contacto con la naturaleza10, 21, 22. Así mismo, los habitantes de la montaña presentaron mayor riesgo de infección por Borrelia que los de la meseta, probablemente debido a que están más expuestos a ser picados por garrapatas puesto que, en estudios previos, se comprobó que los animales de esta zona estaban más parasitados por I. ricinus 2 .…”

“…La enfermedad de Lyme (EL) es una zoonosis cosmopolita causada por una bacteria Gram negativa perteneciente al complejo Borrelia burgdorferi sensu lato y transmitida por la picadura de una garrapata dura del género Ixodes ricinus (I. ricinus) en Europa 1 . La abundancia de esta garrapata dura y de sus hospedadores, así como el aumento de las actividades al aire libre, que generan un mayor contacto del hombre con la naturaleza influyen, entre otros factores, en la seroprevalencia y tasa de incidencia de la EL1, 2, 3, condicionando las diferencias observadas entre países4, 5, 6, 7 y entre regiones de un mismo país3, 8, 9, 10. El número de casos de EL se está incrementando de forma generalizada en toda Europa, hasta el punto de ser considerada una enfermedad emergente1, 11 .…”

The role of the PHCC doctor is essential for achieving an early diagnosis of Lyme disease, as a higher percentage of seropositives was detected in samples submitted from PHCC. Furthermore, most early localised LD patients were diagnosed in PHCC, avoiding the appearance of sequelae. Therefore, detection of Borrelia specific antibodies using an ELISA assay is a useful screening test for patients at risk of LD.
