Compromised nutrition in gerbils infected by Cystoisospora felis detected through an animal performance analysis tool Comprometimento nutricional em gerbis infectados por Cystoisospora felis detectado através de uma ferramenta de análise de desempenho animal

Revista Brasileira de Parasitologia Veterinária, 2011
The impact of Cystoisospora felis infection on the nutritional efficiency of gerbils was studied. The variables weight gain and feed intake were measured during four weeks in 28 laboratory gerbils, of which 14 were inoculated with 3.5 × 10(5) sporulated ...

Occurrence of Cryptosporidium oocysts in US wastewaters [PDF]

Journal of Water and Health, 2006
Wastewater samples collected from ten wastewater facilities across the US were analyzed to determine the occurrence of indigenous Cryptosporidium oocysts using methods based on modifications of USEPA Method 1622. Wastewater facilities participating in this study ranged in size from 0.6 to 193 mgd average daily flow.

Pattern of oocyst shedding (oocyst/g feces) of Dex-treated SCID mice.

, 2012
Experimental groups were inoculated with intended doses of 1, 10, 100 and 105 oocysts. Each point represents one mouse, the lines being the geometric means of oocyst shedding per group. Only animals with oocyst shedding at a precise moment of the day are

Survey of coccidia on commercial broiler farms in Colombia: frequency of Eimeria species, anticoccidial sensitivity, and histopathology

Poultry Science, 2021
: Avian coccidiosis continues to be one of the costliest diseases of commercial poultry. Understanding the epidemiology of Eimeria species in poultry flocks and the resistance profile to common anticoccidials is important to design effective disease ...

Ultrasonic treatment of Cryptosporidium oocysts

Water Science and Technology, 2003
The effect of 20 kHz ultrasound on the viability of Cryptosporidium oocysts was investigated. More than 90% of the dispersed Cryptosporidium oocysts could be deactivated in about 1.5 min of continuous sonication. In order to apply this technique to large quantities of contaminated water, quantitative filtration and redispersion of Cryptosporidium ...
