Prvi dokaz rikecije Anaplasma ovis u oboljelog ovna

چکیده
Krajem svibnja 2015. godine u Laboratorij za parazitologiju, Hrvatskog veterinarskog instituta, Zagreb, Hrvatska dostavljena je krv ovna iz okolice Benkovca sa sumnjom na piroplazmozu. Ovan uz potpornu terapiju vitaminima AD3E i B-kompleka liječen imidokarbom (Imizol 0,5 mL s/c) oksitetraciklinom (Geomicin retard 5 i/m) te pet dana prestao pokazivati kliničke znakove bolesti. U razmazu krvi pronađena su periferno smještena intraeritrocitarna tjelešca, a sekvenciranjem odsječka 16S rRNK MSP4 gena dokazali smo vrstu Anaplasma ovis, dok DNK drugih uzročnika nije bila prisutna. Ovim istraživanjem po prvi puta A. ovis Hrvatskoj, ali Jugoistočnoj Europi. Od danas priznatih osam vrsta anaplazmi, anaplazmozu malih preživača uzrokuju tri vrste phagocytophilum, capra od kojih phagocytophilum dokazana Hrvatskoj. Prema navodima veterinara Veterinarske ambulante Benkovac opisani klinički znaci bolesti česti ovaca ovnova dopremljenih s područja nikada nisu uočeni životinja mlađih mjeseci. Treba naglasiti da osim Imizolom veterinari području oboljele ovce uvijek liječe tetraciklinima što predstavlja lijek izbora, životinje uspješno izliječe ukoliko lijekove apliciraju unutar pojave kliničkih znakova Vektor krpelj Rhipicephalus bursa prisutan diljem Republike Hrvatske ujedno pronađen oboljelom ovnu. Stoga treba očekivati uzročnik drugim dijelovima Hrvatske.

Discrimination Between Anaplasma marginale and Anaplasma ovis by PCR-RFLP
Several tick-borne diseases with different etiological agents such as rickettsia, protozoa, bacteria and viruses can infect domestic ruminants. The only common feature between these diseases is that they can all be transmitted by ticks. Of these, Anaplasma spp. can cause diseases in the livestock with high economical losses. The Giemsa staining of blood smear is the common traditional method fo...
متن کاملHuman Anaplasmosis and Anaplasma ovis Variant
To the Editor: Anaplasmosis is a disease caused by bacteria of the genus Anaplasma. A. marginale, A. centrale, A. phagocytophilum, A. ovis, A. bovis, and A. platys are obligate intracellular bacteria that infect vertebrate and invertebrate host cells. A. ovis, which is transmitted primarily by Rhipicepha-lus bursa ticks, is an intraerythrocytic rickettsial pathogen of sheep, goats, and wild rum...

The present study was conducted as the first molecular detection of Anaplasma species in tick samples based on the sequencing of major surface proteins 4 (msp4) gene fragments in different parts of Iran. A total of 130 tick specimens were collected from Hormozgan, Lorestan, and Guilan, Iran, within 2015 to 2017. Hyalomma asiaticum, Hyalomma dromedarii</em...
متن کاملMolecular study on infection rates of Anaplasma ovis and Anaplasma marginale in sheep and cattle in West-Azerbaijan province, Iran
This study was carried out to determine the presence and frequency of Anaplasma ovis and Anaplasma marginale in sheep and dairy cattle in West-Azerbaijan province, Iran. A total number of 200 blood samples were randomly collected via the jugular vein from apparently healthy cattle (100) and sheep (100). The extracted DNA from blood cells was screened using genus-specific (Anaplasma...
