Un suivi mensuel de l’infestation par les tiques de 48 bovins choisis dans six elevages a ete realise entre avril 2006 et mars 2007 en Algerie dans les localites de Mila (etage bioclimatique semi-aride) et d’El Tarf (etage bioclimatique humide). Au total, 7 024 tiques appartenant a quatre genres et dix especes d’ixodides ont ete collectees : Rhipicephalus (Boophilus) annulatus (62,7 p. 100 des tiques collectees), R. turanicus (13,6 p. 100), Hyalomma scupense (13,6 p. 100), R. bursa (7,7 p. 100), H. marginatum (4,7 p. 100), H. excavatum (3,9 p. 100), H. anatolicum (2,3 p. 100), Haemaphysalis punctata (1,5 p. 100), Ixodes ricinus (0,7 p. 100) et Hyalomma lusitanicum (0,4 p. 100). L’espece la plus frequente dans la wilaya (collectivite publique territoriale) d’El Tarf a ete R. annulatus (77,7 p. 100). En revanche, H. scupense (39,2 p. 100) et R. bursa (17,7 p. 100) ont ete dominants dans la wilaya de Mila. De nombreuses especes de Hyalomma et de Rhipicephalus ont eu une activite continue durant l’annee avec une intensite d’infestation maximale en ete pour R. annulatus et H. scupense, et vernale a automnale pour R. bursa. L’abondance des especes mesophiles a ete faible. Elles ont eu une activite hivernale pour I. ricinus, present uniquement a El Tarf, et automnale pour Hae. punctata, observee uniquement a Mila. L’intensite d’infestation a ete significativement plus elevee chez les bovins adultes que chez les bovins ages de moins d’un an. La phenologie des differentes especes de tiques a parfois differe en fonction des pays limitrophes, montrant ainsi une grande adaptabilite des tiques et la necessite de realiser des etudes regionales avant la mise en place de tout programme de lutte contre les tiques ou les pathogenes qu’elles transmettent.

Single Figure

The detailed structure of the spiracles in the Ixodoidea has hitherto received little or no attention at the hands of zoologists; at the same time, these organs are sufficiently extraordinary to make it a matter of surprise that, so far as our knowledge of the literature goes, not one of the numerous contributors to the subject of tick anatomy has found it worth while to undertake a complete description or to publish figures to illustrate it. Batelli (1891) gives a short account of the structure of the spiracle of a tick, presumably Ixodes ricinus, with a single figure, but with this exception we have been unable to find any further information on the subject.

Abstract This chapter discusses the impact of climate change on the abundance and distribution of babesiosis vectors and, by implication, transmission of Babesia spp. It discusses evidence for climate change impact on the vectors Ixodes ricinus, Dermacentor reticulatus, Haemaphysalis punctata and Hyalomma spp. as well as the absence of evidence of the same climate change effects on the vectors Rhipicephalus spp. and I. scapularis.

De mars à août 2009, nous avons examiné 120 chiens dans deux régions bioclimatiques de l’extrême nord-est de l’Algérie (10 chiens par mois et par région) pour estimer le taux et l’intensité d’infestation de cette espèce par la tique Rhipicephalus sanguineus. Tous les chiens examinés étaient parasités et 895 tiques adultes ont été prélevées. R. sanguineus a été la seule espèce trouvée dans la région de Souk-Ahras alors que dans la région d’El-Kala elle représentait 77 p. 100 des tiques collectées. Deux autres espèces ont été identifiées dans cette zone, Ixodes ricinus et Haemaphysalis punctata, dans des proportions respectives de 13 et 10 p. 100. La charge parasitaire des chiens de Souk-Ahras, région semi-aride, par R. sanguineus a été de 9,4 tiques par chien alors qu’elle n’a été que de 4,2 pour les chiens d’El-Kala, région humide. La différence était très significative (p < 0,01). Les tiques ont été présentes de façon continue durant toute la période d’étude. Ces résultats sont à prendre en considération dans les projets de lutte contre les tiques infestant le chien, notamment contre Rhipicephalus sanguineus, responsable de la transmission de maladies vectorielles chez les humains comme chez les animaux.

In order to evaluate the prevalence rate of Babesia spp. in ticks collected from vegetation at seven localities in northern Serbia, tick samples were subjected to molecular analysis. A total of 132 unfed adult ticks of five different species (Dermacentor marginatus, Dermacentor reticulatus, Ixodes ricinus, Haemaphysalis concinna and Haemaphysalis punctata), were examined by PCR for the presence of Babesia spp. Out of the analyzed ticks, 10.61% (14/132) were positive for babesial DNA. The presence of babesiae was found at the localities Pancevacki Rit, Titov Gaj, Makis, PKB and Kljajicevo. Prevalence in D. reticulatus ticks was 21.57% (11/51) and in H. concinna ticks, 8.57% (3/35). Sequencing and phylogenetic analysis showed a clustering of the obtained sequences with those of B. canis from the GenBank database. These results add to the knowledge of the distribution of babesial pathogens and their vectors in Serbia.

The study regarding tick fauna and season distribution of ticks of small ruminant in the south part of Serbia, with emphasis on north Kosovo was performed during 2017. During the study we examined a total of 114 flocks of goats and sheep from Zvečan and Leposavić districts (villages Ceranja, Majdevo, Zemanica, Mure, Rudine, Žitkovac, Oraovica, Mošnica, Donji Krnjin, Belo brdo, Mioliće, Drenova and Beliće). Infections occurred at and on 56.14% of examined sheep and 31.42% of examined goats. The most abudant tick species were Ixodes ricinus, followed by Dermacentor marginatus, Rhipicephalus sanguineus, R.bursa, Haemaphysalis punctata and D.recticulatus.

Research on vectors and zoonozes in Serbia has been going on for more than a decade now. Due to the climate changes during the last years, the presence of vectors has changed and also the presence of zoonotic agents inside them has changed, too. Vectors that can be found are ticks, mosquitoes, flies, etc. Ticks that can be found in Vojvodina are Ixodes ricinus, Dermacentor marginatus, Rhipicephalus sanguineus, Rhipicephalus bursa, Haemaphysalis punctata. The most common diseases known as tick borne in Vojvodina are piroplasmosis, Q fever and Lyme disease. The study done recently has shown that the presence of ticks can be found throughout the whole year in Northern part of Serbia (Vojvodina province). During the last five years different surveys have shown that ticks in Serbia are infected with B. burgdorferi s.l. at a rate of 25-30%, depending on the region. Also, a number of clinical cases of Lyme disease has been registered in humans and dogs. The percentage of ticks infected with B. burgdorferi s.l. in the province of Vojvodina ranges from 25-28%. An analysis of ticks in selected urban regions performed during a three-year period revealed an infection rate of 25%. During the three-year study period, a total of 1224 ticks were collected from different locations in Vojvodina. The dominant species was Ixodes ricinus, accounting for 62% of all collected ticks. Mosquitoes are another vectors that can be found in Vojvodina very often during the warm period of the year (June-October). Diseases that they can carried are blue tongue disease, equine infectious anemia, dirofilariosis in humans and dogs, etc. Diagnostic of dirofilariosis in Serbia begun some 4 years ago when Dirofilaria were found (Dirofilaria immitis and Dirofilaria repens) in dogs and later on in humans. First cases of dirofilariosis were found in dogs during the autopsy as a side finding. The presence of Phlebotominae has been detected in southern Serbia long time ago and they are known as vectors for leishmaniosis. Their presence has still not been detected in Vojvodina. Three years ago ago several dogs were found with clinical signs (epistaxys, cachexia, pale mucosa, skin leisures, blindness, lethargy) and seropositive finding for leishmaniosis in the central part of Serbia and Vojvodina. At first, all of the dogs were infected abroad, but since 2010, few dogs have been found that have never left their homes. During the period 2008-2010 in Scientific Veterinary Institute „Novi Sad“ 23 dogs vere examined for the presence of antibodies against leishmania by ELISA serological method.
