RABBIT COCCIDIOSIS AND ITS CONTROL : A REVIEW
[EN] Coccidiosis causad by Eimeria species, is a
majar parasitic disease of rabbits and is responsible for a
high incidence of morbidity and mortalitv. The incidence of
th1s disease in EuroP.ean countries in 21-60% and in India
13-64%. In commercially rearad rabbits; coccidiosis occurs
.in a subclinical form witti growth retardation and alterad feed
conversion. The disease occurs in two forms, hepatic and
intestinal, the latter being more common than the formar. Presently, the control of rabbit coccidiosis relies almost
entirely on chemical coccidiostats. However, extensiva use of
such arugs in commercial rabbitries has already started
creating problems of drug resistance. In view of the
limitations of chemotherapy, it is imperativa to develop
immunoprophylactic measures against rabbit coccidiosis.
These incluae development of live-attenuated and
recombinant vaccines against the parasite.[FR] La coccidĂose provoquĂ©e par des esp_eces du genre Emeiria
est la principafe maladie parasitaire affectant le lapin. Elle est
respqnssble de la morb1dité et de la mortalité a fréquence
élevée. Dans les pays européens, son incidence est de 21 a
60% dans les troupeaux, ene est de 13 a 64% en lnde. Dans
les Ă©levages commerciaux de lapins la coccidiose se
manifeste sous fonne subc/inique p_rovoquant des retareis de
croissance et une rĂ©duction de l'effĂcacitĂ© alimentaire. Cette
maladie se manifeste sous deux formes, hĂ©patique et intestina/e, la seconde Ă©tant plus frĂ©quente que la premĂere.
Actuellement le contr6/e de la coccidiose chez le lapĂn est
presque exclusivement basé sur l'emploà de coccidiostats
chim1ques. Cependant l'usage intensif des ces médicaments
commence a créer des problemes de résistance aux
anticoccidiens. AfĂn de limtter la chimĂothĂ©rapie 11 devient
ĂmpĂ©ratif de dĂ©ve/opper des mesures ĂmmunoprophylactĂques
pour lutter contre la coccidiose. Celles-ci
Ăncluent le dĂ©veloppement de lĂg_nĂ©es attĂ©nuĂ©es et de vaccĂns

EFFECT OF IVERMECTIN AGAINST EAR MANGE MITE (Psoroptes cuniculi) IN NATURALLY INFESTED RABBITS
[EN] Thirtv ona New Zealand White rabbits,
naturally infestad with ear manga, were divided into mild,
moderate, severely infestad ané:I infestad-control groups,
basad on their mean lesion seora. Three anĂmafs were
maintained as clean-control group. tvermectin was given
subcutaneously to infested raobits of the 3 first groups, four
times at weekly interval, at a dose level of 20<JÎĽg/kg body
weight. The rabbits with mild infestatĂon showea com1>lete
recovery with two injections. One rabbit each from
moderately and savarely infestad groups, showed persĂstence of mild infestation in the form of presence of
parasitic eggs till 40th day post treatment. The untraatad
mfested-confrol animals sliowad parsistance of infestatĂon
and clean-control animals remained normal throughout the
perlad of study. lt was concluded that ivermectin can be usad
safely, as repeated subcutaneous injections at weekly
interval at a dose of 200ÎĽg/kg 'body weight, for effective
control of ear manga in rabbits. The tmportance of repeated
inlections of ivennectin to control ear manga in severely
infestad rabbits has been dĂscussad.[FR] Trente et un lapins NĂ©o ZĂ©landais Blancs naturellement
infestés par la gtile de l'oreille ont été répartis en groupes dits
légerement, modérémen~ séverement infestés ainsi qu'un
groupe-contr6le infesté etabli a partir de la moyenne des
Tésions. Un groupe contr61e de trois animaux a été maintenu
sans Ănfection. L 'lvermectĂne a Ă©tĂ© administrĂ© en souscutanĂ©
aux lapĂns ĂnfestĂ©s des troĂs premĂers groupes, 4 fois a Ănterva/les d'une semaine, a la dose de 200j.l(J/kg poids vif.
Les lapins légerement infestés ont été tota/étrient guéris
apres 2 injec;tions. Un lapin de chacun des groupes modĂ©rĂ©ment et sĂ©verement ĂnfestĂ©s a gardĂ© un infestation
légere sous forme de présence d'oeufs du parasite persistant
encare au 40eme jour de traitement. Le groupe contr61e de
lapins infestés non traités montre une persistance de
l'infestation et le groupe contr61e non infesté est resté normal
durant toute la perioi:Je expérimentale. On peut en conclure
que l'lvermectine peut ~tre utilisée sans risques en injections
sous cutanĂ©es adminĂstrĂ©es a une semaine d'interválle a la
dose de 200ÎĽg!kg de poids vif pour un contr6le effectif de la
gale des oreilles. L'utilitĂ© des injectĂons rĂ©pĂ©tĂ©es
d'lvermectine a des lapins séverement infestés est discutée.Kurade, N.; Bhat, T.; Jlthendran, K. (1996). EFFECT OF IVERMECTIN AGAINST EAR MANGE MITE (Psoroptes cuniculi) IN NATURALLY INFESTED RABBITS. World Rabbit Science. 04(1). doi:10.4995/wrs.1996.266SWORD04

However, recent increase in extreme heat wave events and enhanced sensitivity of modern poultry genotypes to heat stress has become a major concern leading to significant economic losses to the poultry industry. In India, per capita consumption of poultry meat and eggs is significantly lower than the minimum recommended by Indian Council of the Medical Research and there is need for significant increase in poultry productivity to fulfil these requirements. Conversely, in sub-tropical countries like India where summer is severe, accomplishing higher production under current scenario is a challenge. Earlier intervention strategies including environmental management and nutritional supplementation have been inconsistent in poultry for managing heat stress. Therefore, there is scope for exploring innovative approaches, including genetic marker-assisted selection of poultry breeds for increased heat tolerance and application of molecular techniques in poultry breeding to improve poultry productivity in a sustainable manner. Hence, keeping in view the present situation, it is essential to understand various cellular and molecular mechanisms involved in poultry production including physiological and immunological aspects of the poultry birds under heat stress using molecular biology tools that can help in development of poultry breeds which are better adapted to changing climate.Not Availabl
