The first report of Hepatozoon spp. (Apicomplexa, Hepatozoidae) in domestic cats from São Paulo state, Brazil

Teak (Tectona grandis Linn. F.) is one of the most important forest crops in Brazil, occupying areas in different regions, such as Goiás, Mato Grosso, Paraná, and São Paulo states. Teak wood is used for many purposes such as shipbuilding, rolling and plywood, firewood, and charcoal. In May 2011, teak symptomatic feeder root samples, exhibiting inconspicuous, small galls, were collected in the municipality of Piracicaba, São Paulo State, Brazil (22°41′46.90″S, 47°38′36.84″W). Specimens were identified through perineal patterns and esterase phenotypes of 20 adult females (1,2). Perineal patterns and esterase phenotypes were consistent with those described for Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 and M. javanica (Treub, 1885) Chitwood, 1949. Perineal patterns of M. arenaria showed a low dorsal arch, compressed dorsolaterally, with lateral field marked by some forked and broken striae; no punctate markings between anus and tail terminus were observed. Perineal patterns of M. javanica were rounded, with low dorsal arch, striae smooth, lateral field distinct, clearly demarcated from striae by parallel lines. From the esterase electrophoresis we obtained A2 (Rm:1.2;1.3) and J3 (Rm:1.0;1.25;1.4) phenotypes, typical from M. arenaria and M. javanica, respectively. To our knowledge, this is the first report of M. arenaria parasitizing teak roots in Brazil and elsewhere (new host) and the first report of M. javanica infecting teak in the State of São Paulo. Previously, M. javanica was reported to be infecting teak-growing areas in the State of Mato Grosso (3). This finding has a great importance, not only by the inclusion of these parasites in teak pathological scenario, but also for predicting possible damage in plant species used in teak-based intercropping systems.

Rio Grande Reservoir

A chytrid fungus Olpidium gregarium was found in Rio Grande Reservoir as rotifers populations' parasite. Along the reservoir central axis, the rotifers density decreased in the dam direction, while the density of affected rotifers by the chytrid fungus increased in the same direction. Moreover, some rotifers species were more affected than others, thus showing certain preference for some rotifers species. Thereby, this parasite may be interfering in the distribution of rotifers population in Rio Grande Reservoir. This is the first report of this species for Brazil.

The aim of this study was to report the mite species found in association with the eared dove, Zenaida auriculata (Des Murs, 1847), in São Paulo State, Brazil. A total of 34 bird specimens was examined, and mites were found on 31 of them. The following numbers of mite species were found: Astigmata: Falculiferidae - three species; Analgidae - two species; Dermoglyphidae, Epidermoptidae, Hypoderatidae and Pyroglyphidae - one species each. Prostigmata: Cheyletidae, Cheyletiellidae and Syringophilidae - one species each. Mesostigmata: Macronyssidae and Rhinonyssidae - one species each. We present the first report of Z. auriculata as host of Diplaegidia columbae Buchholz, 1869; Diplaegidia columbigallinae Cerny´, 1975; Byersalges talpacoti Cerny´, 1975; Pterophagus spilosikyus Gaud & Barré, 1992; Hypodectes propus (Nitzch in Giebel, 1861), Ornithocheyletia columbigallinae Fain & Bochkov, 2002; Ornithonyssus bursa (Berlese, 1888) and Tinaminyssus zenaidurae (Crossley, 1952).

During a field survey in 1994, five cucumber (Cucumis sativus) cv. Hokushin plants showing symptom of yellowing, mottling, and vein banding on the leaves were collected from a commercial field of the Federal District. By electron microscopy, quasi-spherical particles with double membrane, typical tospovirus-like particles were found in the infected leaf material. All samples strongly reacted with antibody of zucchini lethal chlorosis tospovirus (ZLCV), but not with antibodies of other to-spoviruses reported in Brazil (1): tomato spotted wilt virus (TSWV), tomato chlorotic spot virus (TCSV), groundnut ringspot virus (GRSV), chrysanthemum stem necrosis virus (CSNV), or iris yellow spot virusonion isolate (IYSV-BR). The virus was identified as ZLCV, which was first isolated in 1994 from zucchini (Cucurbita pepo) in São Paulo State, Brazil. Tomato (Lycopersicon esculentum) plants showing stem necrosis and necrotic spots and rings on the leaves were collected in Viçosa, Minas Gerais State. By electron microscopy, molecular studies, and enzyme-linked immunosorbent assay with antibodies of the six tospoviruses occurring in Brazil, the virus was identified as CSNV. This virus was first reported in 1995 on a Chrysanthemum sp. in São Paulo State and recently reported in the Netherlands from Dendranthema indicum. This is the first report of the natural occurrence of ZLCV and CSNV on cucumber and tomato, respectively. Reference: (1) A. C. de Ávila et al. 1998. Pages 32–34 in: Int. Symp. on Tospoviruses and Thrips in Floral and Vegetable Crops, 4th.
