In this study, milk and blood samples collected simultaneously from 532 trade cows to be slaughtered at Bodija abattoir, Ibadan (southwestern, Nigeria) were examined for antibodies to Brucella using the milk ring test (MRT) and the rose bengal test (RBT). Overall, 18.61%of the milk samples were positive according to the MRT, while 9.77 % of the serum samples were positive according to the RBT. The difference was highly significant (Chi-square value 16.33; P<0.05); only 32 (6.02 %) of the samples were positive for both tests. The Red Bororo breed of cattle and the White Fulani had the highest positive rates, namely 20.93 % and 11.69%for the MRT and RBT respectively.No conclusion can be drawn about sensitivity because we do not know the true status of the animals tested. It is, however, obvious that although the MRT and RBT are 1st-line screening tests for brucellosis in cows in some countries, their lack of specificity is of concern. Therefore, the requirement for other confirmatory tests that are more specific should be considered for control and eradication of the disease, especially in Nigeria.

Introduction. Down syndrome is the most common chromosomal disorder, with a worldwide frequency of 1 case in 700 live births. Objectives. Starting from the hypothesis that with the increased life expectancy of the patients with Down syndrome, new phenotypic changes and new dysfunctions are expected to appear, we proposed a longitudinal study to analyze their evolution over a long period of time. Material and method. This is a longitudinal study, based on retrospective research and descriptive evaluation, performed on a group of 81 patients from the case series of the Bihor Regional Center for Medical Genetics from Oradea. Results. We have identified 4 types of evolutionary trends of the clinical signs: stationary, involutive, progressive and with late onset. Conclusions. Knowledge of the natural evolution of the signs and symptoms of the disease is indispensable in the long-term monitoring of patients with Down syndrome. The birth of a child with Down syndrome is a real drama for the family with a strong emotional impact that can be prevented or mitigated by facilitating prenatal diagnosis, psychological counselling, social support and specialized genetic advice.

Bruceloza je zarazno oboljenje domaćih, divljih životinja i ljudi, rašireno u celomsvetu. Dijagnostika bruceloze putem izolacije uzročnika je veoma teška, dugotrajnai predstavlja rizik od infekcije. Iz tih razloga, serološke metode predstavljaju metodeizbora.Cilj rada je bila uporedna analiza specifi čnosti i osetljivosti testova za dijagnostikubruceloze koji se rutinski koriste na teritoriji Republike Srbije.Ukupno je ispitano 120 uzoraka krvnog seruma goveda na prisustvo specifi čnihantitela protiv Brucella spp. Svi serumi su prvo ispitani primenom Rose Bengal testa.Uzorci koji su pokazali pozitivnu reakciju su zatim ispitivani primenom iELISA i cELISAtesta. Izračunavanje osetljivosti i specifi čnosti seroloških testova je sprovedenona osnovu dobijenih rezultata.Analizom osetljivosti i specifi čnosti zaključeno je da su obe metode (Rose Bengaltest, iELISA test) visoko osetljive (100%, 92%) sa razlikom od 8% u korist iELISA testa,koji se pokazao i kao daleko specifi čnija metoda (91%) u odnosu na Rose Bengaltest (69%).Uporednom analizom rezultata dobijenih u ispitivanju osetljivosti i specifi čnostiRose Bengal testa i indirektne imunoenzimske metode (iELISA) u otkrivanju specifičnih antitela protiv Brucella spp. u krvnim serumima goveda, utvđena je većaosetljivost i specifi čnost metode iELISA u odnosu na Rose Bengal test.
