Oliveira,Tiago Mendonça de; Teixeira,Cristina Mara; Arcebispo,Thiago Luiz Mendes; Antunes,Karla Dias; Rezende,Leandro do Carmo; Cunha,Lucas Maciel; Diniz,Soraia de Araújo; Silva,Marcos Xavier.
ABSTRACT: This study was accomplished with the aim to evaluate and to characterize the risks for the presence of Megninia spp. in poultry farms from Minas Gerais, using for that Correspondence Analysis (CA). A secondary database was used and adapted for this study, with information from 402 chicken houses of 42 laying hens commercial properties. Variables used to compose the correspondence model were selected through tests of Qui-square being considered the significant result of P≤0,05. A risk index was built to the presence of Megninia spp. starting from variables considered as risk factors for the presence of those ectoparasites. The CA graph produced for the epidemiological characterization of the presence of Megninia spp. presented an accumulated...

Laminosioptes cysticola in free-range chickens in Minas Gerais, Brazil Ciência Rural
Martins,Nelson Rodrigo da Silva; Resende,José Sérgio de; Marques,Marcus Vinícius Romero; Barrios,Priscilla Rochelle; Fernandes,André Almeida; Montresor,Lângia Colli; Cunha,Lucas Maciel.
The subcutaneous acarid parasite Laminosioptes cysticola, the fowl cyst mite, has been found for a number of years in free-range chickens of peri-urban and rural Minas Gerais, forming collagen cysts which may be subsequently calcified after the parasite's death. The role of free-range chickens as hosts and the possible risk of food-borne human allergy, as a result of its consumption in feed, are considered.

Mites affecting hen egg production: some considerations for Brazilian farms Ciência Rural
Rezende,Leandro do Carmo; Cunha,Lucas Maciel; Teixeira,Cristina Mara; Oliveira,Paulo Roberto de; Martins,Nelson Rodrigo da Silva.
The poultry industry is characterized for its constant search for productivity and profitability, which are based on flock health status. Brazilian Commercial laying hens (Gallus gallus domesticus) have been impacted significantly by mite infestations. This review aims to compile the literature on the occurrence, economic losses, biology, epidemiology and control of mite species considered important for the Brazilian laying poultry industry. The national experience was compared with practices of other countries and a scarcity of studies on this subject in Brazil was evident. The poultry industry has prioritized the use of pesticides to control infestations with little regard for the adverse effects. In this context, the integrated control programs using...
