Shortly I would like to mention the current situation with TBD in humans in Latvia. These diseases are very common and numbers are roughly the same for the last decade (in the 90ties there was an increase in the incidence). TBE and Lyme disease are the most commonly diagnosed diseases. Anaplasmosis/erlichiosis – only 12 cases in last 9 years and only one of these cases initially had anaplasmosis/erlichiosis as a differential diagnosis. So not enough information is around for humans and even more so for dogs.
Detection methods and dog populations vary! Anaplasmosis in Nordic countries: Sweeden 17.7% dogs suspected to have sarcoptic mange were positive. UK – dogs suspected to have TBD Germany – healthy and sick dogs together Poland – dogs from Lyme borreliosis endemic area Baltic countries – no data. Borreliosis – In Poland and Finland – have been case reports. There are several papers on borrelia in ticks in Finland (but I could not find papers on dogs). Based on what our neibours have it is believable that we will have anaplasmosis and Lyme disease in our dogs. And probably babesiosis in those that are travelling.
Clinically healthy dogs (group 1) and dogs with clinical signs suggestive of TBD (group 2) and hunting dogs (Group 3) were enrolled in the study. Blood was drawn from all dogs and analyzed hematologically (analyzer and microscopy) and with IDEXX SNAP 4Dx test which detects antibodies against Anaplasma phagocytophilum, Erlichia canis, Borrhelia burgdorferi and Dirofilaria immitis. Information regarding tick exposure and ectoparasite control habits was collected from the owners of the dogs enrolled in the study. PCR will be performed for those dogs that are clinically sick, have Anaplasma morulae in the blood and are seropositive on the SNAP test. (PCR testing will be done later in the study).
Atšķirības starp grupām nav statistiski nozīmīgas, domājams, ka tas mainīsies palielinoties izmeklēto dzīvnieku skaitam. 1.Grupā – 16/161 = AP - 3/161= BB - 1= AP&BB 2.Grupa – 4/20=AP - 1/20=EC* - 1/20= AP&EC* 3.Grupa – 3/24 = AP
As is described in the literature – our findings show that dogs with clinical anaplasmosis have significant thrombocytopenia.

Ērču pārnēsātas slimības (ĒPS) cilvēkiem Latvijā
• 2009. gadā
– Ērču encefalīts - 328 gadījumi
– Laimas slimība – 720 gadījumi
• Kopš 2001. gada
– Anaplazmoze/erlihioze – 12 gadījumi
* statistiski nozīmīga atšķirība starp grupām (z=1.134, One-tailed z-test for two proportions)
Anaplazmoze Borelioze Erlihioze Babezioze
1.grupa 2.grupa 3.grupa
• Anaplazmoze ir samērā izplatīta suņiem Latvijā
• Jāpopularizē profilaktisku pasākumu nozīme
• Nepieciešams vairāk informācijas par
B.burgdorferi seroprevalenci suņiem Latvijā
• Babeziozes gadījumi no Latvijas neizceļojušiem
suņiem nav konstatēti
