Espanjalaisista punkeista löytyi riketsiaa, ehrlichiaa ja borreliabakteereita.
Vuoden 1985 jälkeen on tähän mennessä todettu jo kahdeksan uuden riketsian aiheuttavan infektioita ihmiselle. Rickettsia helveticaksi nimetty, alun perin Ranskasta löydetty riketsia on nykytiedon mukaan ainoa Skandinavian alueella esiintyvä riketsia. Ruotsissa on todettu 22 % punkeista kantavan tätä bakteeria. Vuonna 1999 julkaistiin ensimmäiset potilastapaukset, joissa osoitettiin Rickettsia helvetican aiheuttavan infektion ihmiselle. Julkaisussa esiteltiin kaksi potilastapausta, joissa R. helvetica oli aiheuttanut kroonisen sydänlihaksen ja sydänpussin tulehduksen (perimyokardiitin) seurauksena äkillisen potilaan kuoleman.

To determine the tick species that bite humans in the province of Soria (Spain) and ascertain the tick-borne pathogens that threaten people's health in that province, 185 tick specimens were collected from 179 patients who sought medical advice at health-care centres. The ticks were identified, and their DNA examined by PCR for pathogens. Most ticks were collected in autumn and spring (59 and 57 respectively). Nine species of ticks were identified, the most frequent being Dermacentor marginatus (55.7%), Ixodes ricinus (12.4%) and Rhipicephalus bursa (11.9%). Ninety-seven females, 66 males, 21 nymphs and one larva were identified. Twenty-six ticks carried DNA from Rickettsia spp. (11 Rickettsia slovaca, 6 Rickettsia spp. RpA4/DnS14, 1 Rickettsia massiliae/Bar29, and 8 unidentified); two ticks carried DNA from Borrelia burgdorferi sensu lato and seven ticks harboured DNA from Anaplasma phagocytophilum.

Uusia riketsioita on löydetty vuosien 1984 -2004 aikana yhdeksän. Viimeisintä ihmisellekin vaarallista R. felistä on löydetty mm. kirpuista.

Between 1984 and 2004, nine more species or subspecies of spotted fever
rickettsiae were identified as emerging agents of tick-borne rickettsioses
throughout the world. Six of these species had first been isolated from
ticks and later found to be pathogenic to humans. The most recent example is
Rickettsia parkeri, recognized as a human pathogen more than 60 years after
its initial isolation from ticks. A new spotted fever rickettsia, R. felis
was also found to be associated with fleas and to be a human pathogen.
Similarly, bacteria within the family Anaplasmataceae have been considered
to be of veterinary importance only, yet three species have been implicated
in human diseases in recent years, including Ehrlichia chaffeensis, the
agent of human monocytic ehrlichiosis, Anaplasma phagocytophilum, the agent
of human anaplasmosis (formerly known as "human granulocytic ehrlichiosis
agent", E. equi and E. phagocytophila), and finally Ehrlichia ewingii, which
causes granulocytic ehrlichiosis in humans. We present here an overview of
the various tick- and flea-borne rickettsial zoonoses described in the last
20 years, focusing on the ecological, epidemiological and clinical aspects.
