Males and females often differ in their susceptibility and exposure to infection. Thus, they may also differ in their ability to avoid infection. The beetle, Tenebrio molitor, risks infection with cysticercoids when ingesting rat feces containing eggs of the tapeworm, Hymenolepis diminuta. Previous studies demonstrated that beetles sometimes prefer infective feces suggesting that the tapeworm i...

Experiments were conducted to evaluate novaluron as a feed-through larvicide to control immature phlebotomine sand flies (Phlebotomus papatasi Scopoli) (Diptera: Psychodidae). The minimum effective concentration of novaluron against sand fly larvae fed hamster feces treated with novaluron, or feces of hamsters fed a diet containing novaluron, was 9.88 and 9.88 x 10(-1) mg/kg, respectively. Fece...

A large number of microbes existed in animal feces. To provide new sources for discovering new leader of drugs, the diversity of cultivable actinobacteria of animal feces have been studied. Fresh fecal samples of 6 species of herbivore feces were collected. The pure cultures of actinobacteria were isolated from these samples by using 5 media. The 16S rDNA gene sequences of 386 selected strains ...

Efflux pumps are vital bacterial components, and research has demonstrated that some plant compounds such as pheophorbide a (php) possess efflux pump inhibitor (EPI) activity. This study determined the quantity of php present in feces as an indicator of EPI activity. Feces were collected from different species of animals fed a variety of feeds. The chlorophyll metabolites php and pyropheophorbi...

Gut microbes can largely influence the ecology and evolution of mammalian hosts. As research in this area increases, it will be necessary to collect fecal samples from nature to inventory microbial populations. Here, we tested the appropriateness of using feces collected from live-traps for microbiome studies. We found that feces collected from the traps containing the desert woodrat (Neotoma l...

A new real-time PCR assay was successfully developed using a TaqMan fluorescence probe for specific detection and enumeration of a novel bacterium, Lactobacillus thermotolerans, in chicken feces. The specific primers and probe were designed based on the L. thermotolerans 16S rRNA gene sequences, and these sequences were compared to those of all available 16S rRNA genes in the GenBank database. ...

Stable isotope analysis of feces can provide a non-invasive method for tracking the dietary habits of nearly any mammalian species. While fecal samples are often collected for macroscopic and genetic study, stable isotope analysis can also be applied to expand the knowledge of species-specific dietary ecology. It is somewhat unclear how digestion changes the isotope ratios of animals' diets, so...

OBJECTIVE To evaluate the efficacy of and optimize a commercially available culture system for sensitive and specific in-clinic culture of Tritrichomonas foetus from cat feces. DESIGN Prospective study. SAMPLE POPULATION Samples of freshly voided feces from 117 purebred cats and pure cultures of T. foetus obtained from a cat with chronic diarrhea. PROCEDURE Optimal conditions for use of t...

One of the main challenges in understanding the composition of fecal microbiota is that it can consist of microbial mixtures originating from different gastrointestinal (GI) segments. Here, we addressed this challenge for broiler chicken feces using a direct 16S rRNA gene-sequencing approach combined with multivariate statistical analyses. Broiler feces were chosen because of easy sampling and ...

Great differences in capability to detect bacteriophages from urban sewage of the area of Barcelona existed among 115 strains of Bacteroides fragilis. The capability of six of the strains to detect phages in a variety of feces and wastewater was studied. Strains HSP40 and RYC4023 detected similar numbers of phages in urban sewage and did not detect phages in animal feces. The other four strains...
