NARO Makes Breakthrough in the Development of an Anti-tick Vaccine.

Published

Ticks infest cattle negatively impacting health, productivity
and development of the dairy and beef industry resulting into huge economic losses,
especially in sub-Saharan Africa. Annually, the total global costs linked to ticks and tick
vectored pathogens in cattle range between US$ 13.9 billion and US$ 18.7 billion. In Uganda
studies have estimated that losses of over USD 1.1 billion occur annually due to ticks and
tick-borne diseases including East Coast fever (amashuyo amakebe), babesiosis (redwater),
anaplasmosis (kashanku) and cowdriosis (kamunguluze). At farm level, 80% of the total
annual expenses incurred in management all cattle diseases are associated with controlling
tick-borne diseases. For instance, primary ECF outbreak is usually fatal results into a 30%
and up to 100% mortality of the calf crop among indigenous and naive crossbred exotic cattle
respectively on an annual basis. Generally, ticks are considered to be the most resilient and
harmful parasites to the livestock globally.
For more than a century, the control of ticks and tick-bone diseases depended mainly on the
use of chemical acaricides starting with arsenicals. The use of acaricide chemicals has been
favoured by their quick knockdown effect. However, use of chemical acaricides is associated
with the progressive development of global acaricide resistant tick populations which was
first reported in 1937; environmental contamination; and destruction of non-target organisms
notably bees and wild birds. In addition, the development and deployment of new acaricides
has become more costly and yet new acaricides are associated with faster development of
resistant tick populations. Promoting strategic innovations which are environmentally sound
such as the Anti-tick vaccines to control multi-species tick infestations are highly justified.
Vaccines are the most sustainable, effective and environmentally sound alternative for tick
control. Vaccines evolved from classically inactivated pathogens such as smallpox and rabies.
Anti-tick vaccines are designed to induce a protective response in vaccinated animal hosts
such as cattle. When ticks suck blood from vaccinated cattle their body functions are
impaired leading death of many ticks, hence resulting reduced tick populations over time.
The first anti-tick vaccines registered (TickGARD in Australia and Gavac in Cuba) were
designed for the control of tick species that occur in those countries.
Anti-tick vaccines are also cheaper and more sustainable than acaricides. The best approach
is to begin combining vaccination with a rational and not abusive acaricide application. As
vaccination proceeds over time and animals are more protected. This practice translates into a
decrease in tick infestations and the incidence of tick-borne diseases together with the
reduction in the use of acaricides.
In order to control ticks that infest cattle in Uganda, a collaboration was established between
Uganda’s National Agricultural Research Organization (NARO) and a group at the Health

and Biotechnology (SaBio), Institute for Game and Wildlife Research (IREC, CSIC-UCLM-
JCCM), Spain, headed by Prof. Jose de la Fuente. During the last 10 years, this collaboration
has resulted in the development of vaccines specifically targeting ticks that infest cattle in
Uganda (brown ear tick (Rhipicephalus appendiculatus) locally known as Engoha, African
blue tick (Rhipicephalus decoloratus), locally known as entujo and tropical bont tick
(Amblyomma variegatum) locally known as Embarabara. The vaccines were derived from a
protein called Subolesin which was extracted from native tick species. The early research
efforts were undertaken by a NARO staff, Kasaija Paul as part of his PhD work under the
supervision of Prof. Jose de la Fuente and Dr. Marinela Contreras at the University of
Castilla-La Mancha (UCLM), Spain. So far, this collaborative effort has produced two types
of vaccines notably the injectable and oral vaccine anti-tick vaccines. The injectable anti-tick
vaccine is administered in the muscle of cattle around the neck region while oral vaccine is
given to cattle through the mouth or mixed in a suitable cattle meal. The injectable anti-tick
vaccine has been evaluated on 5 farms across the country representing five ecological zones
of Uganda. The farms include Mbarara ZARDI farm in Mbarara City; Kiburara Prison farm
in Ibanda District; Isimba prison farm in Masindi District; Maruzi livestock research station
in Apac District; and Nabuin ZARDI farm in Nabilatuk District. During the 12 months of the
field evaluation trial at Mbarara, Kiburara, and Isimba farms. Trial cattle were sprayed twice
at Mbarara and completely not sprayed at Kiburara and Isimba farms. In addition, during the
ten months of the field evaluation trial, trial cattle were only sprayed once at Maruzi and
completely not sprayed at Nabuin. Trial cattle were sprayed twice. On all the farms, there
were no deaths due to tick and tick-borne diseases during the trial period. NARO has already
obtained a utility model patent for the injectable and oral anti-tick vaccines (UG/U/2023/6)
and efforts are underway to acquire clearance from the national regulatory bodies to register
and recommend use of the vaccines by farmers. After registration and with support of the
Government of Uganda, NARO will massively produce and rollout the vaccine to livestock
farmers in and outside the country.
The collaboration between Ugandan and Spanish researchers with support from national
authorities highlights that working together is the best approach to face socioeconomic
challenges and translate scientific results into new interventions for building a more
sustainable and equitable world.

Ntoroko Edges Kyaka in Thrilling Tooro Kingdom MTN Masaza Cup

Published

By

Agripping showdown at the Humura playground in Kyegegwa district, Ntoroko County FC
secured a narrow 1-0 victory over Kyaka County FC, knocking them out of the Tooro Kingdom
MTN Masaza Cup. Kaswara Ason's decisive 34th-minute goal, the only score in an entertaining
game filled with missed opportunities, sealed Kyaka’s fate in the tournament.
Kyaka FC started the match on a strong note, with Frank Asiimwe showcasing his skills early
on. His solo run in the opening moments set the stage for multiple chances, though none found
the back of the net. Despite their spirited performance, Kyaka couldn't convert their dominance
into goals.
The game, played under challenging weather conditions due to a heavy downpour, saw
moments of high drama. Thomas Mugisa, making his tournament debut, posed a constant
threat. His appeals for a penalty in the 81st minute after a challenge from Ntoroko defender
Michael Bwamble were, however, waved away by the referee, adding to Kyaka’s frustrations as
they hunted for an equalizer.
Ntoroko's victory ensured their spot in the semifinals, joining Burahya, who also advanced as
the best losers of the group stage. Ntoroko County Member of Parliament, Gerald Rwemulikya,
praised his team for their resilience and performance. "Kyaka was at home and they created
many chances. This was our first time playing at Humura playground, but we managed to get a
well-deserved win. I want to congratulate my players and wish them luck in the next stage,"
Rwemulikya said.
Elsewhere in the tournament, Kyaka County became the fourth team to be eliminated, following
Kitagwenda, Kibaale, and Mwenge North. Their exit left the Kyaka county supporters in silence,
contemplating what might have been.
Tooro Kingdom's sports minister, Wandera Michael Enganjani, highlighted the broader
significance of the annual sports tournaments. "These tournaments are meant to promote
talents and fight against HIV/AIDS, which is very high in Fort Portal according to a Uganda AIDS
Commission survey," he said. Enganjani commended MTN Uganda for their continuous support
and promised unwavering cooperation in future events.
Aggrey Byaruhanga, MTN's regional marketing officer, reiterated the importance of health and
safety among the participants and supporters. "I appeal to Tooro Kingdom subjects to continue
testing for HIV and using condoms if they cannot abstain," Byaruhanga stated.
Looking ahead, the Tooro Kingdom MTN Masaza Cup will feature a clash between Fort Portal
City and Bunyangabu County next Sunday at the King Oyo Sports Complex in Bukwali at 3 PM.
The Tooro Kingdom MTN Masaza Cup continues to deliver thrilling football action, with
community engagement and health awareness being vital components of the event's mission.
