ABSTRACT: Felid alphaherpesvirus 1 (FeHV-1) and feline calicivirus (FCV) affect cats worldwide. The aim of this study was to evaluate the frequency of occurrence of FeHV-1 and FCV in cats with clinical signs of respiratory, oral and/or ocular disease. Samples were collected from cats cared for in veterinary ambulatory and clinics and submitted to molecular detection and viral isolation. Of the 49 cats evaluated, 45 (92%) were positive for at least one of the viruses; 82% (40/49) were positive for FeHV-1 and 41% (20/49) for FCV. Of these, 31% (15/49) were coinfection cases. For FeHV-1, 45% (18/40) of the cats tested were positive from the collection of eye swab, and the same percentage (9/20) was obtained for the FCV by the oral swab. FeHV-1 and/or FCV were isolated in 35% (17/49) of the samples. The main clinical sign observed was ocular secretion in 71% (35/49) of cats, characterized as mild serous, purulent or serosanguineous, and in some cases associated with ocular injury and marked chemosis. Our findings demonstrate the high occurrence of FeHV-1 and FCV in domestic cats in southern Brazil and indicate that measures should be implemented to improve the diagnostic, prevention and management against of these important diseases.

The diatom Palmerina hardmaniana (Greville) Hasle presents a wide geographical distribution in neritic tropical and subtropical regions. In the present work we analyzed plankton samples collected monthly between 1995 and 2007 at the surf zone of Cassino Beach, RS (32° 12' S and 52° 10' W), and in winter 2005 and summer 2007 at the continental shelf and slope in southern Brazil, Santa Marta Grande Cape, SC and Albardão-Chuí, RS regions (28° 23'-33° 07' S and 48° 41'-52° 26' W). We present the detailed morphological description of P. hardmaniana, and the first study including electron scanning microscope observations for material from the southwestern Atlantic Ocean. The morphometric data confirm the identity of the species in all its ultra-structural details. Palmerina hardmaniana was only observed in summer-autumn months with low cell density (< 500 cells.L-1) at both Cassino Beach surf zone and coastal shelf stations. The warm water temperature (18-29 °C) indicates the most probable origin of its inoculum are tropical/subtropical regions. Salinities of 23-36 and the relatively high silicate content indicate the importance of the terrestrial discharge during occasions when P. hardmaniana was observed, probably with influence on the nutrient availability. We emphasize that the species was not cited previously for Argentinean and Uruguayan waters and suggest that the southern Brazilian region is close to the southern geographical distribution limit of Palmerina hardmaniana in the southwestern Atlantic Ocean.

Temporary Habitat

The southern population of Mugil liza is distributed from Argentina (47°S) to the state of São Paulo, Brazil (23°S). Young mullets use the estuaries as nursery grounds, and prior to recruitment into estuaries they use the surf zone as a temporary habitat. Based on 12 consecutive months of sampling, this study used generalized linear models (GLM) to analyse the relationships between environmental variables and the presence and relative abundance of young mullets in the surf zone adjacent to six major estuaries in southern Brazil (between 29°S and 33°S). Young mullets were present in all seasons over the sampling period, but the probability of occurrence was higher in winter and was associated with low temperatures. The water temperature alone explained more than half of the total deviance of the GLM models for presence (23%) and abundance (21%) of young mullets in the surf zone. Site 2 (Rio Grande) had lower temperatures in the colder months, the highest probability of occurrence of all collection sites and the greatest abundance (n=3402) of young M. liza, which represented 52% of the total of individuals (n=6493) caught among the six sites sampled.

Explanatory Variables

Surf-zone fish assemblage was investigated to assess its patterns of variability for two sandy beaches in southern Brazil. Fish were collected monthly (July 2009–June 2011), and the hauls were conducted with two different beach seine nets. Generalized linear models were used in the following two different approaches: (1) a Poisson model was used to assess and compare fish species richness; and (2) a logistic and gamma models were used to explain the occurrence and variability in abundance of Mugil liza and Trachinotus marginatus (dominant species). A set of nine explanatory variables was used to explain the patterns of ecological variability. At a large scale, seven variables explain 24.8% of the variance in species richness; and season (16.2%) and beach seine (3.0%) were the most important. The presence of M. liza was associated with beach seine (20.4%), whereas the abundance was associated with beach seine (12.1%) and five other explanatory variables. The presence and abundance of T. marginatus was associated with season (18.6% and 22.3%, respectively). Species richness seems to be strongly related to season, although the choice of net used can play an important role. Warmer months are richer in number of species, and the larger net is able to catch more species than the smaller one.
