20Background 21 Among hematophagous arthropods, ticks transmit the greater variety of pathogens of public health and 22 veterinary importance whose (re)-emergence is recognized worldwide. However, the epidemiological 23 situation of the Caribbean area with regard to tick-borne diseases is poorly documented, mainly focusing 24 on livestock pathogens such as Ehrlichia ruminantium, Babesia (bovis and bigemina) and Anaplasma 25 marginale. These observations underline the need to undertake new large-scale epidemiological surveys 26 to better assess the distribution of tick-borne pathogens and anticipate the risk of (re)-emergence of tick-27 borne diseases in these areas. To ease and reduce the cost of such large-scale surveys, the development 28 of a fast and cheap high-throughput detection technics is desirable. 29

“…The tick Rhipicephalus (Boophilus) microplus is one of the major parasites of cattle because it not only causes reductions in weight gain, quality of coat, and production of calves and milk, but also has the capacity to transmit pathogens (Alonso et al, 1992;Peter et al, 2005;De La Fuente et al, 2008). 8 L. M. Costa-Júnior and J. Furlong stimulated the development of more acceptable methods of tick control that offer reasonable efficiency together with economic viability.…”

The objective of the present work was to evaluate the efficacy of a non-sulphur-based homeopathic preparation and a sulphur-containing natural product derived from Allium sativum (Linnaeus) against infestation by the cattle tick Rhipicephalus (Boophilus) microplus (Canestrini) (Acari: Ixodidae). A total of 24 crossbred calves (7 : 8 Holstein : Zebu), aged 6-8 months and maintained in individual stables under tick-free conditions, were divided into three groups. Group 1 (control group) received no treatment; Group 2 was treated with 0.01 g/day of the homeopathic preparation Fator C&MC(®), and Group 3 was treated with 20 g/day of Enxofre-Allium sativum(®). After adaptation to the diet for 1 month, each calf was subjected to artificial infestation with 8000 R. (B.) microplus larvae (aged 7-14 days) twice per week over a 5-month period. Numbers of engorged females were recorded every 14 days and samples of freely released engorged females were collected at 14-day intervals commencing 3 months after the start of the experiment. The engorged females were weighed, incubated for 15 days under biochemical oxygen demand conditions at 27 ± 1 °C and relative humidity >85%, and the weights of the egg masses produced were recorded. Other biological parameters, including reproduction estimate, reduction in oviposition and efficiency of treatment, were determined. A significant reduction in the number of engorged females was detected on animals treated with Enxofre-Allium sativum(®) (Group 3) in comparison with the other two groups. The overall efficiency of the treatment with the sulphur-containing product was 64%, whereas that of the homeopathic preparation was 26%. Under the experimental conditions established, Enxofre-Allium sativum(®) can reduce the intensity of the R. (B.) microplus infestation.

“…Successful management of BA depends on adequate knowledge of seroprevalence for A. marginale and the risk factors associated with the transmission (Alonso et al 1992). Bovine anaplasmosis is not determined exclusively by the geographical distribution of the tick vector.…”

“…In some regions of Latin America, the disease is more widespread than R. (Boophilus) spp. indicating the existence of other vectors or different modes of transmission, particularly mechanical transmission by biting flies and blood-contaminated fomites (Alonso et al 1992). This mode of transmission of A. marginale is considered to be important in the epidemiology of BA in areas of Central and South America, Africa, and the US (Ewing 1981;Foil 1989;Morley and Hugh-Jones 1989).…”

A cross-sectional study was conducted to determine individual cow seroprevalence of Anaplasma marginale in adult lactating dairy cattle of Puerto Rico (PR) and to assess the associations of farm management factors on herd seroprevalence. Antibody activity against A. marginale was determined using the MSP-5 competitive enzyme-linked immunosorbent assay. Serum samples were obtained from 2,414 adult lactating dairy cattle from 76 randomly selected commercial dairy farms. Herd seroprevalence ranged from 3 to 100% with an overall individual cow seroprevalence for A. marginale of 27.4%. Factors associated with high herd seropositivity were pasture grazing as the main feed source (OR = 6.5, 95% CI = 1.2-34), observed monkeys on the premises (OR = 13, 95% CI = 1.2-138), use of 11% permethrin (OR = 17, 95% CI = 2.2-129), farmers who attended an acaricide certification program (OR = 0.18, 95% CI = 0.04-0.74), and lack of a fly control program (OR = 5.6, 95% CI = 1.3-24).
