“…Lyme borreliosis has been detected in people in the Santa Cruz department, south-eastern Bolivia, whereas dog sera failed to show positive seroprevalence for this pathogen [303, 304]. Ehrlichiosis due to E. canis was reported at a seroprevalence of 86% in domestic dogs [299].…”

A review on the occurrence of companion vector-borne diseases in pet animals in Latin America

Companion vector-borne diseases (CVBDs) are an important threat for pet life, but may also have an impact on human health, due to their often zoonotic character. The importance and awareness of CVBDs continuously increased during the last years. However, information on their occurrence is often limited in several parts of the world, which are often especially affected. Latin America (LATAM), a region with large biodiversity, is one of these regions, where information on CVBDs for pet owners, veterinarians, medical doctors and health workers is often obsolete, limited or non-existent. In the present review, a comprehensive literature search for CVBDs in companion animals (dogs and cats) was performed for several countries in Central America (Belize, Caribbean Islands, Costa Rica, Cuba, Dominican Republic, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Puerto Rico) as well as in South America (Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, French Guiana, Guyana (British Guyana), Paraguay, Peru, Suriname, Uruguay, Venezuela) regarding the occurrence of the following parasitic and bacterial diseases: babesiosis, heartworm disease, subcutaneous dirofilariosis, hepatozoonosis, leishmaniosis, trypanosomosis, anaplasmosis, bartonellosis, borreliosis, ehrlichiosis, mycoplasmosis and rickettsiosis. An overview on the specific diseases, followed by a short summary on their occurrence per country is given. Additionally, a tabular listing on positive or non-reported occurrence is presented. None of the countries is completely free from CVBDs. The data presented in the review confirm a wide distribution of the CVBDs in focus in LATAM. This wide occurrence and the fact that most of the CVBDs can have a quite severe clinical outcome and their diagnostic as well as therapeutic options in the region are often difficult to access and to afford, demands a strong call for the prevention of pathogen transmission by the use of ectoparasiticidal and anti-feeding products as well as by performing behavioural changes.

“…Most of the previous studies evaluated the effect of the administration of tetracosactid only like a stressor [ 17 , 1 , 4 , 16 ], but this is the first report in which the possible role of the drug as a stimulus for steroid output and consequently to stimulate the onset of ovarian cyclicity was studied.…”

Effect of Tetracosactid on Post Partum Cyclicity in Cows after Induction of Parturition with PGF2α

Veronesi MC, Kindahl H, Gustafsson H, Kornmatitsuk B: Effect of tetracosactid on post partum cyclicity in cows after induction of parturition with PGF 2α α . Acta vet. scand. 2001, 42, 243-250. -Parturition and retention of fetal membranes were induced with PGF 2α in 3 primiparous dairy cows. Starting on day 12 post partum (PP) the cows were treated with 500 µg i.m. of ACTH-analogue (tetracosactid) every 6 h for 6 times. Changes in plasma concentrations of cortisol, progesterone and 15-ketodihydro-PGF 2α were evaluated immediately after treatment. The effects on the resumption of ovarian activity were evaluated by clinical and ultrasound examinations and by progesterone and 15-ketodihydro-PGF 2α analyses for 56 days after parturition. Treatment was able to induce a statistically significant (p<0.01) similar increase in cortisol and progesterone after both the 1 st and the 6 th injections, in all cows. No changes in 15-ketodihydro-PGF 2α concentrations were seen after any of the injections of ACTH-analogue. The first corpus luteum (CL) was seen on day 18 PP (cow A), and 28 (cow B) and in both cases it was followed by a normal ovarian cyclicity. No CL was observed during the whole period of study in cow C. Progesterone profiles confirmed these clinical and ultrasonographic findings. The steroid output, especially progesterone, induced by the ACTH-analogue might be a stimulus for the onset of ovarian cyclicity, since 2 of the 3 animals ovulated earlier than expected. These findings point to the fact that interference with the stress system might have a positive effect on ovarian cyclicity. The different pattern of response does however demand further studies.progesterone; cortisol; prostaglandin; metabolite; ACTH.
