“…In 40 hedgehogs tested serologically in Teramo Province, Italy, no positivity was found [ 30 ]. The high prevalence of antibodies against T. gondii assessed in the studied urban hedgehogs is similar to the high antibody prevalences found in feral cats (51.9%) [ 16 ] and pregnant women (28.6%) [ 31 ] in the same MAB. Similarly, significantly higher seroprevalence levels have been reported in wildlife from the same region, in Catalonia, NE Spain, compared to other areas of Spain in several species, including wild rabbits (53.8%) [ 32 ], red deer (42.2%) [ 16 ], wild birds (27.2%) [ 11 ], or even in legally trapped and released common ravens in Catalonia, which showed one of the highest seroprevalences in wild birds worldwide (80.5%) [ 14 ].…”

Toxoplasma gondii is a generalist zoonotic parasite that involves a wide range of warm-blooded animals as intermediate hosts and felines as definitive hosts. Recent studies have proved significant positive associations between human population density and T. gondii seroprevalence in wildlife. However, there is limited data regarding T. gondii wildlife in urban areas, where the highest human density occurs. The present study aimed to analyse the T. gondii exposure in urban hedgehogs from the Metropolitan Area of Barcelona, NE Spain. One hundred eighteen hedgehogs were analysed for the presence of antibodies (modified agglutination test; n = 55) and parasite DNA (qPCR; heart = 34; brain = 60). Antibodies were detected in 69.09% of hedgehogs. T. gondii DNA was not detected in any of the analysed samples. The present study reports a high T. gondii seroprevalence in urban hedgehogs in areas surrounding Barcelona, the most densely human-populated area of NE Spain, reinforcing the association between human population density and environmental T. gondii oocysts. The lack of detection by molecular techniques warrants more studies. In the last few decades, the distribution and abundance of European hedgehogs have declined, including their urban populations. Further research is needed to investigate the impact of T. gondii on hedgehog populations.

“…The seroprevalence of Toxoplasma gondii infection in Spain is unclear, and the reported rates of T. gondii infection vary between 25 and 45% depending on the study. However, the seroprevalence in the city of Barcelona, where the current study was performed, was reported to be 28% [2]. Diagnoses are typically made on the basis of characteristic funduscopic findings, such as a focus of retinitis arising at the border of a retinochoroidal scar.…”

Clinical Pattern of Toxoplasmic Retinochoroiditis in a Spanish Referral Center

et al. 2013

Background/Aims: To analyze the clinical pattern of ocular toxoplasmosis in a referral center in Spain. Methods: The medical records of consecutive patients with ocular toxoplasmosis admitted from a single referral center for uveitis in Barcelona (Spain) were retrospectively analyzed between January 2005 and January 2011. Results: One hundred and thirteen eyes from 113 patients (74 Spanish and 39 South American) with active ocular toxoplasmosis were analyzed with a 12-month follow-up. Final BCVA ≤20/200 was found in 30 eyes (26.5%). The most frequent complications were macular edema (16.8%) and epiretinal membrane (11.5%). Anterior chamber cell scores of ≥2+ (p = 0.003), vitreous cell scores of ≥2+ (p = 0.001), and the presence of cataracts (p = 0.047) or serous retinal detachment (p = 0.008) were more common among the South American than Spanish cohort. Active macular lesions (p < 0.001) with an initial BCVA ≤20/200 (p < 0.001) and advanced age (p = 0.019) were predictors for final BCVA ≤20/200, whereas female gender (p = 0.021) and an initial BCVA ≤20/200 (p = 0.045) were predictors for ocular complications. Moreover, a BCVA ≤20/200 (p < 0.001) and a vitreous cell score of ≥2+ (p = 0.045) at the initial examination were predictors of an eventual need for ocular surgery. Conclusion: The clinical features of ocular toxoplasmosis in Spanish patients differ from those of South American patients. In general, active macular lesions with an initial BCVA ≤20/200 and advanced age were shown to be predictors for final BCVA ≤20/200 in our patient cohort.

“…Previous epidemiological studies reported that the prevalence of Toxoplasma gondii infection in pregnant women varies from country to country, from 9 to 67 % in European countries (Nash et al, 2005), 34.1% in Sudan (Elnahas et al, 2003) and 33% in New Zealand (Morris et al, 2004), 70.9% in Cuba (González-Morales et al, 1995). The toxoplasmosis prevalence was low (28.6%), however, acute toxoplasmosis diagnosed by seroconversion during pregnancy showed 9 women out of 12 had an acute infection with 5 (41.6%) infant congenital toxoplasmosis (Muñoz Batet et al, 2004).…”

Toxoplasmosis during pregnancy has an adverse effect on pregnant women, fetus and neonatal. The infection is generally asymptomatic but can cause severe effect on the fetus and immunocompromised women. Control study conducted on 77 pregnant women categorized according to the risk factors influencing toxoplasmosis infection. Specific anti Toxoplasma gondii IgG and IgM were evaluated using Enzyme-linked immunosorbent assay (ELISA) test kits. Among 77 pregnant women, (57.1%) women had toxoplasmosis, seropositive for latent infection with specific Toxoplasma gondii immunoglobulin G (IgG) antibodies were (54.54 %), whereas acute infection immunoglobulin M (IgM) were only in (2.59 %) cases. The seroprevalence of Toxoplasma was higher in older pregnant women (> 60%) than younger ones (<50%). The specific IgG antibody was higher in pregnant women working in farms (65.7 vs 45.23; P=0.053). Also, the seropositive IgG antibody was low in the first trimester and high in rural areas. Pregnant women need to educate more about toxoplasmosis and prevention to exposure in order to reduce the risk of congenital toxoplasmosis.
