Säo relatados casos de ceratoconjuntivite provocados por Neisseria ovis em rebanho ovino das raças Merino, Ile de France, Ideal, Corriedale e Romny March. Os autores, após identificarem os microrganismo, selecionaram amostras que foram utilizadas para o preparo de vacina. Levando em consideraçäo as provas de patogenicidade experimental, variaçöes biológicas do parasito e fatores que predispöem o globo ocular à infecçäo, concluíram que o microrganismo apresenta capacidade para se instalar e proliferar em terreno previamente sensibilizado, desencadeando o processo oftálmico

Um novo meio (MSE) foi desenvolvido para a conservação e estocagem de espécies de Neisseria patogênicas para o homem. Dez amostras de meningococo e 10 de gonococo foram estocadas neste meio e mantiveram a viabilidade até 8º e 5º mês, respectivamente.

Nonpathogenic Neisseria, normal inhabitants of the human nasopharynx, are known to cause occasional infections including such severe ones as septicemia, meningitis and endocarditis. Recently two strains of so called nonpathogenic. Neisseria, identified as N. subflava, were isolated from blood specimens of two different patients. One patient had meningitis, septicemia and subacute bacterial endocarditis while the other had septicemia. Pigment production by both of the strains was not definite and only a light yellow color was observed after prolonged incubation. However, the isolates showed bacteriological characteristics of N. subflava, namely gramnegative diplococci which were oxidase positive, acid production from fructose, glucose, maltose and sucrose but not from lactose or mannitol; and iodine reacting polysaccharide production from sucrose. One of the patients revealed serum agglutinin titers up to 1 : 640 against the isolate.
