background :    salmonellosis is an infectious and a food-borne disease of humans and animals. the initial source of the infection is the intestinal tracts of birds and other animals. apparently healthy animals can become subclinical carriers and persistently shed salmonella in their feces which can act as a reservoir for the pathogen. the aim of this study is to detect the carriers of salmonel...

McMaster (McM) method is one of the most widely used techniques for assessment faecal parasites shedding in veterinary practices because its simplicity. However, due to light sensitivity, recently, Mini-FLOTAC (MF) has been introduced as a possible alternative worm egg counts. This study aims compare diagnosis performance MF McM technique. Faecal samples from 40 animals randomly selected sheep,...

Abstract Changes in lifestyle and the negative impact of chemicals make people aware dangers consuming food products containing chemical residues so many switch organic food. Black rice is one kinds that widely consumed as an functional because its antioxidant dietary fiber content. has been rarely cultivated it longer harvests age lower productivity than white rice. The way to increase product...

We assessed the distribution of Trypanosoma cruzi infection in peridomestic triatomines collected manually at a district-wide scale in rural villages around Olta, Western Argentina, and typed the isolated strains according to their pathogenicity to laboratory mice. Of 1623 triatomines examined, only 14 (0.9%) were infected with T. cruzi based on microscopical examination of feces. The prevalenc...

Encephalitozoon intestinalis (Septata intestinalis) is the second most prevalent microsporidian species infecting humans, but it has not been described in other animal species. This investigation examined 10 domestic animal stool samples (8 mammalian, 2 avian) containing spores detected by anti-Encephalitozoon monoclonal antibody immunofluorescence (FA). The presence of E. intestinalis but not ...

The natural abundance of 15N (expressed as delta 15N per mil relative to air N2) in the tissues and the change of 15N abundance during the digestion processess in cattle, pig, and goat were investigated. The 15N abundances of cattle tissues differed by about 3.5% with high values in heart, urinary bladder and diaphragm. The ages of cattle did not affect on the 15N abundances of liver and kidney...

Animals have co-evolved with mutualistic microbial communities, known as the microbiota, which are essential for organ development and function. We hypothesize that modern animal husbandry practices exert an impact on the intestinal microbiota. In this study, we compared the structure of the fecal microbiota between feral and domestic goats using the G2 PhyloChip and assessed the presence of fi...

Q fever is a widespread zoonosis caused by Coxiella burnetii. Infected animals, shedding bacteria by different routes, constitute contamination sources for humans and the environment. To study Coxiella excretion, pregnant goats were inoculated by the subcutaneous route in a site localized just in front of the shoulder at 90 days of gestation with 3 doses of bacteria (10(8), 10(6) or 10(4) i.d.)...

Salmonellosis is a disease of human beings, cattle, sheep, goat, pigs and chicken including duck and is manifested clinically in all hosts by one of three major syndromes: a peracute systemic infection, acute enteritis or chronic enteritis. But the clinical signs may vary from species to species1. Human infections with Salmonella have been increasing worldwide since 1980 and have been shown to ...

Isolation rates of Campylobacter spp. were analyzed for an 8-year period, 1978 through 1985. Three laboratories of the Ontario Ministry of Health examined 146,842 human feces samples for bacterial pathogens, including Campylobacter jejuni and Campylobacter coli. Campylobacter spp. were isolated from 5,580 specimens (3.8%), with monthly isolation rates ranging from 1.1 to 7.4%. The data showed a...
