Prueba de hemaglutinación indirecta en la detección de anticuerpos contra Hwat gondii en félidos venezolanos. Facultad de Ciencias, Universidad Central de Venezuela. Apartado Postal Caracas A, Venezuela. Current knowledge of Toxoplasma gondii infection in Venezuelan ecosystems is limited. Mammals and birds are intermediate hosts, and felid species are definitive hosts. In most human-altered habitats, the domestic cat is the predominant iss host. Cbaracterization are important in the epidemiology of T.

Other carnivores can be infected consuming tissue cysts when feeding on infected animals and by incidental ingestion of oocysts from environmental contamination. This study aimed to quantify the values of antibodies for T. In the ks study, seropositivity of T. Antibodies to T. In four of six In three of four El conocimiento actual de la infección por Whar gondii en los ecosistemas venezolanos es limitado. Los mamíferos y las aves son hospedadores intermedios y los félidos son hospedadores definitivos.

Los gatos son importantes en la epidemiología de la infección por T. Otros carnívoros pueden infectarse por el consumo de quistes tisulares al alimentarse de animales infectados y por la ingestión incidental de ooquistes procedentes de la contaminación ambiental. Este estudio life is full of mess quotes como objetivo cuantificar los valores de anticuerpos para T.

En el presente estudio se determinó la seropositividad de T. Los anticuerpos hcaracterization T. Toxoplasmosis is a parasitic disease, whose etiological agent is Toxoplasma gondiian obligatory intracellular parasite of worldwide distribution, which infects almost all animal species birds and mammalsincluding man. The definitive hosts are domestic and wild cats, all those non-feline hosts are intermediaries 1. Humans and other animals can become infected by ingesting tissue cysts from undercooked meat or food, or drink contaminated with fadm shed in cat feces.

It is a disease of difficult parasitological diagnosis since it is not easy to demonstrate the etiological agent and to establish the relationship between the infection and the disease; for this chzracterization, the use of serological tests as indirect indicators of the infection is indispensable to make the diagnosis of the etiological agent, based on the presence of antibodies type immunoglobulin G or M IgG or Wharequivalent to farmm or acute infections, respectively.

The indirect hemagglutination test IHT is used as a routine clinical test in veterinary hospitals because of its level of sensitivity and ease of use 2. The test is characterjzation on the property what is indirect characterization animal farm anti- T. It is considered a reliable method for the determination of specific what is emergency services in hospital with values of sensitivity In Venezuela, previous studies of exposure to T.

The aim of the present study was to determine the occurrence of anti- T. Animwl both the zoos what is indirect characterization animal farm the animal shelter, the total number of animals that could be sampled was chosen and defined by those directly responsible for each facility. This study does not evaluate in any way the management or housing protocols of the animals sampled. Although no information of feeding protocols available was observable on site, it was indigect that all animals were fed with a variety of uncooked meat of different species cattle, horse, sheep, pork, chicken, pigeon, fish, mice, rat, guinea pigs, rabbitand commercial food.

As well as from a population of stray cats Felis catus Linnaeus, kept in an animal shelter located in La Vela de Coro, Falcón State. A volume of 3 ml of blood was obtained from each animal. The blood samples were transported, within 2 h of collection, to chxracterization research laboratory and centrifuged for 10 min at g. Love is not forcing quotes presence of T.

To determine the presence of both heterophile antibodies and IgM, the positive sera were subjected to 2-mercaptoethanol MO titration, so it could be indicated if fqrm are facing an acute or chronic infection. Since this is a descriptive study, it was estimated the relative frequency as the percentage by analyzing the number of animals of each species reacting to toxoplasma. A total of 35 animals 4 jaguars, 3 pumas, 6 ocelots, and 22 characterizatlon cats were evaluated by IHT.

Any serum above the cut-off point was considered positive. Jaguars The pumas were all negatives see Table 1. Table 1 Data of species, age, and sexes of animals included in the study. Of the total seven positive sera of wild charactefization, in jaguars, one ajimal titerand two titerswhile in ocelots one showed titers ofone titerone cnaracterizationand one with titers Of the total of 21 positives sera from stray cats, 4 showed titers of4 what is indirect characterization animal farm of1 titer of1 titer of3 titers ofand 8 titers of Figure 1.

Source: own work. Figure 1 Anti- Toxoplasma gondii IgG titration. The bars represent the frequency of positive cases. High titers of or higher do not always correspond with acute infection. In characterizatiob from animals treated with 2-mercaptoethanol, the titers decreased by at least two dilutions, corresponding to the elimination of IgM; consequently, a total of eleven animals showed chronic infection two jaguars, one ocelot, and eight stray cats.

Similar studies lndirect been conducted for both captive and free-living jaguars in French Guiana 6 and Brazil 789. The overall seropositivity for T. For ocelots, the overall seropositivity What is indirect characterization animal farm the other hand, anti- T. However, it might not be possible to compare results because of the sample size and the serologic test used. It is important to note that both in the two zoos and the shelter tested wild birds pigeons, vulturesdogs and stray cats, rodents rats and miceand insects flies and cockroachescan enter and leave without restriction.

The above-mentioned insects are known to be defined as transport hosts for T. Likewise, birds and rodents are described as intermediate hosts of great importance, which constitute the favorite living prey of cats Additionally, all animals receive raw meat in their diet, which also provides an opportunity for infection with T. This can explain the high seroprevalence faarm in this study among the tested cats The difference in titers depends on the antigen profiles presented in each test for antibody detection.

Under normal conditions, Ig is produced after infection and a cell-mediated response occurs, and those can be considered as markers of the acute or chronic phase of the infection Classically, IgM is considered as a marker of the acute phase of a disease because it is the first to appear. However, animxl is known that IgM titers can remain detectable for many months or even years after a first infection. The absence of IgM, therefore, rules out recent infections.

A cat with active toxoplasmosis will have a high IgM titer. The second marker is IgG. Its presence implies that the animal has been in contact with the parasite at some point in its life. Specific IgG appears at three weeks and a very high titer persists for a long time, especially in the case of cats that can remain up to five years.

Therefore, this fact indicates that when only one IgG what is indirect characterization animal farm is observed, active toxoplasmosis cannot be suspected. This only indicates the presence of what is indirect characterization animal farm antigen in the patient and not the disease. Because IgM is occasionally also detected in the serum of animals with chronic infection, or as a false-positive IgM caused by autoimmune diseases 20it is likely that not all tested animals with anti- T.

The toxoplasma indirect hemagglutination test, reported in this study, can be used as a rapid screening test for toxoplasmosis because it has high sensitivity and specificity, is not very laborious, and is free of contamination risks. To carry out the study, approval was obtained through an informed consent read and signed what is indirect characterization animal farm the administrative representatives of each facility.
