A method was developed to recover Eimeria spp. oocysts directly from poultry litter and determine which species of Eimeria were present using polymerase chain reaction (PCR) based on the ITS1 rDNA sequence. The species composition of Eimeria oocysts was also compared before and after propagation in susceptible chickens to determine if the relative proportion of each species changed after expans...

Necrotic enteritis (NE) is an emerging economically significant problem of poultry caused by a bacterium Clostridium perfringens. The rising incidence of Clostridium infections and development of NE in commercial chickens has been associated with the withdrawal of antibiotics. There is an urgent need to control NE after European ban on the use of antibiotics as growth promoters in animal feed. ...

Background: Artemisinin is commonly used for the treatment of malaria, but recently has been considered as a potential substance to control poultry coccidiosis. OBJECTIVES: The aim of the present study was to determine the tissue distribution of artemisinin following single or multiple oral administration of different doses in broiler chickens. METHODS: A total number of 390 one day old Ross br...

Avian coccidiosis is caused by intracellular protozoan parasites in the genus Eimeria. It has a significant economic impact on the poultry industry and is highly prevalent in chicken producing countries worldwide. Current control measurements including good animal husbandry, chemoprophylaxis, and vaccination cannot effectively control the disease. It is well understood that parasites repeatedly...

The efficacy of three polyether ionophores viz. salinomycin, monensin and maduramicin was evaluated in poultry. Dayold chicks (n=350) were randomly divided into seven groups of 50 chicks each. The drugs were administered as feed premix from day one onwards. The chicks at 14-day of age were initially infected with 20,000 sporulated viable oocysts of Eimeria tenella and challenged with 40,000 spo...

BACKGROUND MLF2 was the candidate gene associated with coccidiosis resistance in chickens. Although single marker analysis supported the association between MLF2 and coccidiosis resistance, causative mutation relevant to coccidiosis was not identified yet. Thus, this study suggested segregation analysis of MLF2 haplotype and the association test of the other candidate genes using improved data ...

A survey was conducted (March 2020 to October 2020) on biosecurity practices, disease occurrence and antimicrobial usage of 77 broiler farms from five districts Northern Kerala. Data were collected through a questionnaire field-level diagnostic tests conducted. Biosecurity status varied farm with 97.4 per cent promoted vaccination 61.04 disposed carcasses by burning. However, limitations observ...

Avian coccidiosis is the most important parasitic disease in poultry production, which inflicts numerous losses to the industry. The extensive use of anticoccidial drugs leads to parasite resistance and drug residue in poultry products. In the present study, we aimed to investigate the effects of three famous essential oils (EOs) and their combination on inactivation of mixed oocysts of Eimeria...

Metam sodium (MS, sodium N-methyldithiocarbamate) is a widely used soil pesticide. Fumigation or chemical sterilization of poultry litter containing infectious oocysts could be an effective strategy to block the transmission of avian coccidia. In the current study, the effect of MS on the viability and infectivity of ocysts was investigated. The development of isolated, unsporulated oocysts of ...
