Infection dynamic of Toxoplasma gondii in two fattening pig farms exposed to high and low cat density in an endemic region

SUMMARYA total of 207 wild rodents were caught on nine pig farms, five chicken farms and five non-farm locations in Sweden and surveyed for a selection of bacteria, parasites and viruses.Lawsonia intracellulariaand pathogenicYersinia enterocoliticawere only detected in rodents on pig farms (9% and 8% prevalence, respectively) which indicate that these agents are more likely to be transmitted to rodents from pigs or the environment on infected farms.Brachyspira hyodysenteriae(1%),Brachyspira intermedia(2%),Campylobacter jejuni(4%),Campylobacter upsaliensis(2%), leptospires (7%) and encephalomyocarditis virus (9%) were also detected from rodents not in contact with farm animals.GiardiaandCryptosporidiumspp. were common, although no zoonotic types were verified, andSalmonella entericawas isolated from 1/11 mice on one farm but not detected by PCR from any of the rodents.Trichinellaspp. andToxoplasma gondiiwere not detected.

This study is aimed to assess the prevalence and risk factors associated with T. gondii infection in pigs. We evaluated 143 pigs, in 10 randomly-chosen farms located in Southern Piauí. The pig's blood serum was analyzed through ELISA in detection of anti-T. gondii antibodies. A seroprevalence of 25.5% was observed in the pigs that reacted against T. gondii antigens. The data from the records demonstrated an association with some factors such as: age, diet, type of management, breed and presence of cats in the farms with a prevalence of T. gondii. With the exception of sex, all others features represent risk factors for T. gondii infection. Furthermore, our data contributed to the understanding of the T. gondii seroprevalence in pig farms located in Southern Piauí.

Toxoplasmosis is an important worldwide zoonosis caused by the protozoan parasite Toxoplasma gondii. This parasitic infection is often asymptomatic in immunocompetent people. However, if the infection occurs in pregnant women, it can have serious consequences for the foetus. In this study, we evaluated the seroprevalence of T. gondii in women of childbearing age in Arad County, Western Romania. Serum samples from 2626 women were analysed using a Siemens ADVIA Centaur XP Immunoassay System. Toxoplasma gondii IgG antibodies were demonstrated in 1081 women (41%) and prevalence tended to increase with age, from 32% in women aged 15–19 years to 62% in women aged 40–45 years. There was a higher prevalence in rural areas (46%) than in urban areas (36%). This study provides new data on T. gondii seroprevalence in women of childbearing age from Western Romania.
