AbstractMedical Officers (MOs) and Medical Branch Ratings (MBRs) must maintain an awareness of the risk of vector-borne diseases among deployed personnel.Personnel working in the maritime environment may not expect to be at risk of tick bites, as ticks typically occupy habitats with dense vegetation such as forests or scrub land. However, tick-borne pathogens can cause serious and sometimes fatal disease, and therefore the risk of tick bites and associated diseases should be recognised.We present a case of a tick bite in a member of a ship’s company eight days after leaving port. The tick was identified as a brown dog tick (Rhipicephalus sanguineus), a species known to thrive indoors. We describe several important tick-borne diseases which can be transmitted by R. sanguineus and explore best practice for tick removal and aftercare. Finally, we outline the appropriate management of suspected tick-borne disease in deployed personnel in the maritime environment.

Rhipicephalus sanguineus, the brown dog tick, is endemic throughout the world wherever domestic dogs are present. It has been recently reported by some veterinarians in the city of Laredo, Texas, USA, that Lyme disease, the most common tick-borne disease in the Northern United States, is present in local domestic dogs. Fully engorged R. sanguineus ticks were collected and their DNA was purified. The ticks were screened to determine the prevalence of Borrelia, Rickettsia and Ehrlichiaspecies. Sequences related to Borrelia burgdorferiin 9.8% (n=11/112), “Candidatus Borrelia lonestari” in 16.9% (n=19/112) and Ehrlichia canis in 12.5% (n=14/112) were detected by PCR. Sequencing has confirmed the presence of DNA from Ehrlichia canisand “Candidatus B. lonestari”, corroborating that Borrelia and Ehrlichia are present in domestic dogs in South Texas.

Examination of ticks collected from ehrlichiosis positive dogs revealed the occurrence of Rhipicephalus sanguineus. The distribution of ehrlichiosis in dogs is related to the spreading of vectors. Ehrlichia canis is the etiologic agent of canine monocytic ehrlichiosis (CME) and recognized as the most prevalent tick-borne disease affecting dogs and is transmitted by the brown dog tick Rhipicephalus sanguineus with an expanding global distribution. Infection of the vertebrate host occurred when an infected tick ingested a blood meal which in turn contaminated the feeding site with its salivary secretion. Blood transfusions from infected donors can also transmit the organisms. Hence, identification of ticks is necessary to detect the disease affecting dogs.

Tick borne pathogens present a significant health challenge to animals and human because a single tick may transmit multiple pathogens to a mammalian host during feeding. The present study detected tick-borne pathogens from pet dogs. A total of 666 ticks were collected from 144 pet and sheltered dogs in Egypt from April to September 2018. For hemolymph, midgut and salivary gland smears 546 ticks were used as well as 360 egg smears from 120 female tick were examined by light microscope. The infected ticks were prepared for transmission electron microscopy (TEM). Ticks were identified; Rhipicephalus sanguineus. Light microscopy showed infection rates of 44.69%, 68.50% & 15.75%, in hemolymph, midgut and salivary gland, respectively. H. canis recorded the highest rates in hemolymph and midgut (35.89% & 49.82%, respectively), but Theileria spp. was the lowest (0.73% & 2.93%, respectively). In salivary gland smears, Babesia canis. was detected in 13.55% and Theileria spp. in 1.83%. Mixed infection in same tick was recorded in 4.76% &0.37% in midgut and salivary gland smears, respectively. Babesia canis stages were recovered from 15% of egg smears. R. sanguineus was natural infected by Babesia, Theileria, Hepatozoon and Anaplasma phagocytophilum as well as mixed infections of protozoa accompanied by a complicated sign of diseases and failure in accurate diagnosis.

Living Organisms

Vectors are living organisms that transmit infectious diseases from an infected animal to humans or another animal. Biological vectors such as mosquitoes, ticks, and sand flies carry pathogens that multiply within their bodies prior to delivery to a new host. The increased prevalence of Vector-Borne Diseases (VBDs) such as Aedes-borne dengue, Chikungunya (CHIKV), Zika (ZIKV), malaria, Tick-Borne Disease (TBD), and scrub typhus has a huge impact on the health of both humans and livestock worldwide. In particular, zoonotic diseases transmitted by mosquitoes and ticks place a considerable burden on public health. Vaccines, drugs, and vector control methods have been developed to prevent and treat VBDs and have prevented millions of deaths. However, development of such strategies is falling behind the rapid emergence of VBDs. Therefore, a comprehensive approach to fighting VBDs must be considered immediately. In this review, I focus on the challenges posed by emerging outbreaks of VBDs and discuss available drugs and vaccines designed to overcome this burden. Research into promising drugs needs to be upgraded and fast-tracked, and novel drugs or vaccines being tested in in vitro and in vivo models need to be moved into human clinical trials. Active preventive tactics, as well as new and upgraded diagnostics, surveillance, treatments, and vaccination strategies, need to be monitored constantly if we are to manage VBDs of medical importance.

Coereba Flaveola

During a survey for ectoparasites on birds in a small reserve of the Brazilian cerrado (savannah) a male adult Rhipicephalus sanguineus tick was found attached to the eyelid of the bird Coereba flaveola. Both tick and bird are presently common in Brazil, however, to best of our knowledge, the association of this tick species with this bird species has not been reported before. This observation may be an accidental finding but might also be an unknown route for the dissemination of the tick. The species R. sanguineus was introduced in the country with the colonization and should be considered a research target for the surveillance of tick-borne diseases.
