Role of the polymorphic immunodominant molecule in entry of Theileria parva sporozoites into bovine lymphocytes by Toye, Philip G., Musoke, A.J., Naessens, Jan

“…We also demonstrate that PIM antigen, as a recombinant molecule, can also reduce sporozoite infectivity in vitro by blocking both attachment and internalization of sporozoites. Electron microscopic studies showed that PIM is present in microspheres below the sporozoite surface and is transported to the parasite surface soon after contact with bovine lymphocytes. …”

The porcine cervix : morphological changes and infiltration of immune cells during oestrus and dioestrus in the sow by Edström, Karin

“…However, little is known about the parallel microscopic changes in the cervix. Therefore, the aim of this study was to examine the histological properties of the epithelium and subepithelial connective tissue of the uterine cervix during oestrus and dioestrus; the morphology of the epithelium and the infiltration of cells of the immune system were described. …”

Fungi Associated with Postharvest Decay of Persimmon in Spain by Palou, Lluís, Montesinos-Herrero, Clara, Guardado, Aurora, Besada, Cristina, Del-Río, Miguel A.

“…Isolated fungi were plated in potato dextrose agar (PDA) Petri dishes and incubated at 25°C for further macroscopic and/or microscopic identification. Although identification of few pathogens causing minor decay is pending, results indicated that the main causal agents of latent and wound infections were Alternaria alternata and Penicillium spp. …”

Solanum glaucophyllum intoxication in goats: Case study by Barale, Joaquín, Ovelar, Florencia, Lázaro, Fermín, Scioli, Maria Valeria, Canton, German Jose, Garcia, Juan Agustin

“…Lesions were characterized by multiple rough white plaques, and hardened tissues with loss of elasticity. Microscopically, multisystemic mineralization was observed in aorta and carotid arteries, heart, lung, abomasum, intestine, spleen, lymph nodes, kidney, spleen, and meninges, characterized by extensive granular basophilic deposits of tunica media and/or intima of blood vessels; confirmed as calcium salt deposits with Von Kossa stain. …”

Natural occurrence of the entomopathogenic genus Pandora on spittlebug pests of crops and pastures in Argentina by Foieri, Alvaro, Pedrini, Nicolás, Toledo, Andrea

“…The entomopathogenic fungal species were characterized on the basis of morphological keys and molecular techniques. Microscopic characters were described from material mounted in lactophenol/aceto‐orcein (1% w/v), and the amplification of the fungal SSU rDNA was carried out using the universal primers nu‐SSU‐0021‐5′ and nu‐SSU‐1780‐3′. …”
