1. Evaluation of a Feed Plant Additive for Coocidiosis Control in Broilers Herbals for Coccidiosis Control
ABSTRACT Coccidiosis negatively impacts health and productive performance in broilers. Anticoccidial resistance has prompted alternatives to prevent and control this disease. Therefore, the objective of this study was to evaluate a plant feed additive consisting of Acacia concinna containing saponins (Peptasan®) and compare its effectiveness with salinomyci

2. Isospora machadoae sp. nov. (Protozoa: Apicomplexa: Eimeriidae), a new coccidian species from white-necked thrushes Turdus albicolis (Passeriformes: Turdidae) of South America
ABSTRACT A new coccidian species parasitizing white-necked thrushes Turdus albicollis Vieillot, 1818 is described from the Parque Nacional do Itatiaia, in Southeastern Brazil. Isospora machadoae sp. nov. has oocysts that are sub-spherical, 22.2 × 21.2 µm, with bilayered wall, ~1.3 μm thick. Outer layer is rough with micropyle and micropyle cap. Oocyst res

3. Opportunistic and non-opportunistic intestinal parasites in HIV/ AIDS patients in relation to their clinical and epidemiological status in a specialized medical service in Goiás, Brazil
ABSTRACT Patients infected with the Human Immunodeficiency Virus (HIV) often have opportunistic infections, among which strongyloidiasis and coccidiosis are the most common parasitic infections that aggravate their health status. This study examined the prevalence of intestinal parasites, particularly of Strongyloides stercoralis and intestinal coccidia in p

4. Ultrastructural Assessment of the Integrity of the enteric Mucosa of Commercial Turkeys Vaccinated against Coccidiosis
ABSTRACT The objective of this study was evaluated the villus integrity of commercial turkeys submitted to coccidiosis prevention methods and challenged with Eimeria field oocysts, using scanning electron microscopy. Sixty BUT 9 female commercial turkeys were distributed in a completely randomized block design split with two treatments: T1- control diet with

5. Effects of glutamine on performance and intestinal mucosa morphometry of broiler chickens vaccinated against coccidiosis
ABSTRACT This study aimed to assess the effects of glutamine as feed additive on performance and intestinal mucosa morphometry of broiler chickens vaccinated against coccidiosis. A total of 400 day-old male chicks were randomly assigned to four treatments (NVNG – no vaccination, no glutamine supplementation; NVG – no vaccination, glutamine supplementatio

6. The economic impact of infection with Eimeria spp. in broiler farms from Romania
ABSTRACT A survey was conducted on chicken broiler farms from Romania in August-November 2010 to evaluate economic losses due to coccidiosis. Data were collected from six broiler farms of different capacity regarding chemoprophylaxis program, weight gain, feed conversion, and mortality, for two previous flocks in two houses of each farm, and finally we evalu

7. A Review of Approaches Targeting the Replacement of Coccidiostat Application in Poultry Production
ABSTRACT The classical and the most commonly used approach for the prevention of coccidiosis in chickens is the incorporation of synthetic coccidiostats into their feed during the first weeks of their life. This approach has been challenged by consumers, objecting against residual antimicrobials and drug resistant microorganisms that may contaminate poultry

8. Ação trófica de aditivos fitogênicos, glutamina e ácido glutâmico sobre a Bursa de Fabrícius e intestino delgado de frangos de corte
Abstract The aim of this study was to evaluate the effect of phytogenic additives and glutamine plus glutamic acid, associated or not, on histomorphometry of bursa of Fabricius and small intestine, oocyst count and lesion scores, and carbon turnover of duodenal mucosa of broiler chickens infected with Eimeria acervulina. A total of 450 male broiler chickens

9. Sources of trophic action on performance and intestinal morphometry of broiler chickens vaccinated against coccidiosis
The aim of this experiment was to evaluate the effect of sources of trophic action (glutamine alone, glutamine associated with glutamic acid and yeast) associated with vaccination against coccidiosis on the performance and morphometry of the small intestine of broilers. In the trial, 1,200 broiler chicks were distributed according to a completely randomized

10. Infeções por Eimeria em caprinos do Sul de Portugal
A coccidiose causada por espécies de Eimeriaé a maior infecção intestinal que afeta regimes intensivos e semi-intensivos de caprinos. A região do Alentejo é a mais importante na indústria caprina em Portugal. Assim, todas as 15 explorações de caprinos da raça Serpentina do Alentejo foram analisadas para determinar a frequência e diversidade de esp

11. Saccharomyces Cerevisiae cell wall dietary supplementation on the performance and intestinal mucosa development and integrity of broiler chickens vaccinated against coccidiosis
This study was carried out to verify if Saccharomyces cerevisiae cell wall (SCCW) dietary supplementation (0.2%) was capable of protecting the intestinal mucosa of broiler chickens vaccinated against coccidiosis. Body weight gain, feed intake, feed conversion and intestinal mucosa morphometric parameters and epithelial loss were evaluated. In the experiment,

12. PARASITOSES E DESEMPENHO ANIMAL: ESTUDO META-ANALÍTICO EM FRANGOS DE CORTE E SUÍNOS EM CRESCIMENTO / PARASITOSIS AND ANIMAL PERFORMANCE: META-ANALYTICAL STUDY IN BROILER AND GROWING PIGS
Dois trabalhos foram desenvolvidos com o objetivo de estudar, através de meta-análise, a relação das parasitoses com o desempenho de frangos de corte e suínos. As bases de dados totalizaram 43.976 frangos de corte (69 artigos, publicados entre 1982 e 2010) e 1.279 suínos (18 artigos, publicados entre 1971 e 2010). A meta-análise foi realizada através
