Monthly serological follow-up of the antibody titres against Leishmania infantum in hunting dogs in rural southern Spain was carried out during the transmission period (from April to October in 1996). Titres > or = 160 were regarded as indicating disease, while lower positive tires were also recorded as 'seropositive'. Over this period, a significant (p < 0.05) increase in the percentage of dogs with a titre > or = 160 was observed; from 12.6% in April to 19.2% in October. The same pattern was observed with the seropositives (titre > or = 20) which increased from 36.3% in April to 55.6% in October. Of seronegatives in April, 60% were still negative in October whereas 22% had a titre of 20-40 and 18% had a titre > or = 80. Similarly, 68% of those with a titre > or = 80 in April still had a titre in this range in October, 25% of the titre had decreased to 20-40 and in 7% to a zero titre. The most noteworthy is that 25% of animals reached titres of > or = 80 and decreased to zero or 20 more than once. Parallel to this study, another survey was conducted on dogs from Granada city centre. The seroprevalences (titres > or = 160) at the start and the end of the transmission period were 1.7 and 3.7% respectively and the seropositively values were 12 and 11% respectively.

Membranoproliferative glomerulonephritis (MPGN) has previously been used as an umbrella term to describe a spectrum of hypocomplementemic glomerular diseases, which are rare causes of end stage kidney disease (ESKD). We present a 22-year-old man with a well-established medical history who had been complaining of 4 days of frothy dark urine, bilateral lower limb swelling, and puffiness on his face. For a month before his presentation, he had many bilateral skin lesions on his lower limbs that were leaking pus.

Case Summary: is a globally distributed apicomplexan protozoan infecting all warm-blooded animals. Cats are the definitive host, susceptible to clinical disease. In Spain, studies have shown the widespread presence of IgG antibodies in cats but there are no published data on clinical toxoplasmosis in cats from Spain.

Background: Despite its proven effectiveness and safety, there are limited real-world data on CoronaVac's immunogenicity in children, especially in lower-income countries, particularly for SARS-CoV-2 variants. We present a real-world study evaluating CoronaVac's immunogenicity in Colombian children stratified by previous exposure to this virus.
Methods: 89 children aged 3-11 years were enrolled (50 Non-Exposed and 39 Exposed).

Background: The multipositivity of myositis-specific antibodies (MSAs) is uncommon. Our study aimed to assess the prevalence and the clinical relevance of multiple positive MSAs in routine practice.
Methods: A 10 year single-center retrospective study (2015-2024) was conducted reviewing all samples analyzed with the Dot Myositis EUROLINE (Euroimmun Germany).

The Coombs test is important in hematology for detecting erythrocyte-bound IgG antibodies or in serm through agglutination methods, but its sensitivity and specificity are limited. Flow cytometry provides a more precise and sensitive alternative for quantitatively assessing RBC-bound IgG antibodies. This assessment is crucial for evaluating the risk of hemolytic reactions and ensuring safe transfusions.
