“…microplus, which was found on the marsh deer, B. dichotomus. This tick is a major pest of cattle and the vector of Babesia bovis and Babesia bigemina, the causative agents of bovine babesiosis (Guglielmone 1992). The ability of B. dichotomus to serve as an alternative host for R.…”

“…The study was carried out in the Estación Experimental Agropecuaria Rafaela (31°11′S, 61°29′W) in Santa Fe province, Argentina. The study area is in the Argentinean region free of Boophilus microplus Canestrini (Acari: Ixodidae) ( Guglielmone 1992), but scabies, lice and Stomoxys calcitrans L. (Diptera: Muscidae) infestations, and myiasis due to Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae) can occur on cattle, and the presence or absence of these parasites was recorded for the experimental cattle.…”

The horn fly Haematobia irritans L. (Diptera: Muscidae) has recently spread to Argentina and Uruguay and is believed to cause damage to cattle hides. Four groups of ten Holstein steers each were maintained for 58 weeks under different infestation levels with H. irritans to determine if it was the cause of this problem. Hides (chrome tanned) from steers maintained under minimum infestation level had 4.7 +/- 3.8% of the area damaged. Maintaining the steers under low H. irritans level for the last 44 days of the trial using insecticidal ear-tags, resulted in 29.5 +/- 15.8% of hide area being damaged. Steers that were treated with 5% cypermethrin pour-on, when the H. irritans population was close to 50 flies, showed that 31.3 +/- 16.6% of hide area was injured, and 46.6 +/- 12.8% of damaged hide area was found in hides from non-treated steers. Significant differences were found between mean hide damage from steers maintained continuously under low H. irritans infestation levels and all other groups. Hyperaemia was significantly lower in the skin of steers under low H. irritans infestation level than in the skins of non-treated steers and steers maintained under low-level infestations for the final 44 days. Eosinophil and mononuclear cell infiltration was significantly lower when the population of H. irritans was less than six per steer than when the population was more than 100 flies per steer. Low numbers of Stomoxys calcitrans were found in all groups, but most hide damage was presumed due to H. irritans.

“…The presence of Rhipicephalus ticks in all countries in which positive cattle were found suggests that these ticks are potential transmission vectors of Babesia sp. Mymensingh (Goolsby et al, 2016;Guglielmone, 1992;Kolonin, 1995;Liyanaarachchi, Rajakaruna, Dikkumbura, & Rajapakse, 2015;Roy et al, 2018;Vudriko et al, 2016). However, only experimental infections in cattle with Babesia sp.…”

Bovine babesiosis represents a serious threat to the cattle industry in the tropics and subtropics. Although several Babesia species infect cattle, only B. bovis, B. bigemina and B. divergens are known to cause clinical babesiosis. However, our recent study demonstrated that the newly discovered Babesia sp. Mymensingh might be a virulent species capable of causing clinical babesiosis in cattle. The objective of this study was to determine the host range and geographical distribution of Babesia sp. Mymensingh on a global scale. A total of 2,860 archived DNA samples from 2,263 cattle in Sri Lanka (n = 672), the Philippines (n = 408), Vietnam (n = 460), Uganda (n = 409), Brazil (n = 164) and Argentina (n = 150); 419 buffalo in Sri Lanka (n = 327) and Vietnam (n = 92); and 127 goats and 51 sheep in Vietnam were screened using a Babesia sp. Mymensingh‐specific PCR assay. Babesia sp. Mymensingh infection was detected in cattle, buffalo, sheep and goats. Cattle of all countries surveyed in this study except Brazil were found to be infected with Babesia sp. Mymensingh. The highest positive rates were recorded in cattle from the Philippines (11.3%) and Vietnam (9.6%), followed by Argentina (4.7%), Sri Lanka (1.5%) and Uganda (1.0%). Buffalo were found to be infected with this parasite in Sri Lanka (1.2%) and Vietnam (10.9%). Unexpectedly, Babesia sp. Mymensingh was also detected in sheep (2.0%) and goats (1.3%) from Vietnam. These findings were confirmed by PCR amplicon sequencing. In conclusion, our present findings indicate that Babesia sp. Mymensingh, which infects cattle, buffalo, sheep and goats, is endemic in Asia, Africa and South America.
