     The study was conducted on 65 local adult chickens (Gallus domesticus) to investigate  macro - and microscopically presence of external and internal parasites and their prevalence in Sulaimani region-Kurdistan/Iraq from May to July 2012. Results showed that 90.77 % out of total examined chickens were infested with ecto-parasites, out of that 81.36 % (48/59) were infested with lice such as (Menacanthus  stramineus, Goniocotes  gallinae, Menopon  gallinae, Goniodes  gigas, Cuclotogaster  heterographus ) and 62.72 (37/59) of it with larval stage of soft tick such as (Argas  persicus).  Mixed infestations with more than two ecto-parasite species were detected. On the other hand 89.23% out of 65 examined chickens were infected by internal parasites including nematodes and cestodes such as (Heterakis  gallinarum which formed 81% and the remains were Ascaridia  galli, Cheilospirura  hamulosa, Capillaria  spp., Raillietina  spp., Choanotaenia  infundibulum, Amoebotaenia  sphenoides, Hymenolepis  carioca and  Davaniea  proglottina).

The rickettsiae (Rickettsiales: Rickettsiaceae) are obligate intracellular and Gram-negative bacteria. They depend on arthropod vector as well as the mammalian host for survival in the nature. 327 soft tick specimens associated the aviary were collected in Khorramabad county of Lorestan province, western Iran. Ticks were identified as Argas persicus according to taxonomical key. Then, 64 tick specimens were analyzed for the presence of rickettsial DNA. Out of 64 specimens, 6 of them were positive and totally three DNA sequences including a single sequence of each ompA, ompB and sca4 genes was obtained from A. persicus ticks. Rickettsia hoogstraalii was detected in Ar. persicus representing the first record of this species in Iran. Sca4 gene fragment was unable to specify rickettsial infection in Ar. persicus ticks according to BLAST analysis.

Micro Organisms

Ticks transmit a greater variety of pathogenic micro-organisms than any other arthropod vector group, and are among the most important vectors of diseases affecting animals. A survey on the prevalence of tick species infesting domestic birds sold in Gwagwalada main market, Abuja between April and July, 2015. A total of 450 birds were examined by feather separation with fingers and a pair of forceps to expose the skin of the birds for presence of the ticks. An overall prevalence of 25.6% was observed. Out of the 150 domestic fowls examined 62(53.9%) were infested, 44(29.3%) of the 150 Guinea fowl and 9(6.0%) of the 150 Pigeons were infested. Of all the ticks identified, 93(51.4%) were from the Domestic Fowls and 77(42.5%) from the Guinea fowl and 11(6.0%) from Pigeon. Thirty (32.3%) of the ticks from the Domestic fowls were Argas persicus, 25(26.9%) Argas walkerae, 20 (21.5%) Ornithodorus moubata and 18(19.4%) Ornithodorus savignyi. Similarly, 34(44.2%) of the ticks from Guinea fowl were A. walkerae, 20(28.2%) O. moubataand 23(32.4%) O. savignyi. Five (45.5%) of the ticks from Pigeon were A. persicus, 4 (36.4%) were A. walkerae, 2 (18.2%) were O. moubata and no O. savignyi. Observation on the location of tick from the hosts body showed highest prevalence was found under the wings (55.2%) and lowest on the head & neck (5.00%). The result of this research revealed that Gwagwalada market poultry section is endemic of tick infestation. Chemical control with acaricides and improved management and sanitation of the poultry cages in the market should be enforced.

Abstract The sand tampan, Ornithodoros savignyi (Audouin, 1827), is an economically important soft tick of the Afrotropics parasitising a wide range of livestock and humans. These ticks are known to inflict painful bites which may be fatal in susceptible hosts. Historically thought to be a single species, Ornithodoros savignyi is now considered to be a complex of four tick subspecies based on molecular and morphological studies. They include Ornithodoros (Ornithodoros) kalahariensis, O. (O.) pavimentosus, O. (O.) noorsveldensis and O. (O.) savignyi. As such there may be significant implications for previous biological studies conducted on this tick. Therefore, for the purposes of this review, sand tampan toxicosis and potentially useful biological molecules have been discussed for O. (O.) savignyi sensu lato since most reported work was based on ticks collected from the Kalahari and Lake Chad region. An overview of the host range and vector biology for the O. (O.) savignyi species complex will also be examined.
