“…A total of 67 individuals belonging to 17 species of non-volant small mammals were captured with pitfall and live traps ( Figure 6 and Table 5). Previous studies on parasites of small mammals carried out in SBNP also recorded Akodon montensis, Delomys sublineatus, Oligoryzomys nigripes, and Monodelphis scalops (Moraes et al 2003;Silva et al 2007), which were not recorded in the present study. In the present study, Didelphis aurita was the most abundant marsupial species and Delomys the most abundant genus among rodents.…”

Here we present a commented list of mammals registered in the Serra da Bocaina National Park. Three field trips (February, 2010, and May and July, 2011) were accomplished along the RJ-165 highway in the Municipality of Paraty, State of Rio de Janeiro, Brazil. Forty-eight species belonging to nine orders were recorded. The local mammal fauna could be considered diverse and rich, with some species regarded as biological indicators of habitat quality. Endangered and rare rodent species like Blarinomys breviceps, Juliomys rimofrons, and Thaptomys nigrita were captured. Road and hunting impacts on mammals are discussed.

“…Six ocelots and 1 jaguarundi were positive (24.1%) by PCR. Three of them were co-infected with M. haemofelis and 'Candidatus M. haemominutum' (2 ocelots and 1 jaguarundi), and 4 with only 'Candidatus M. haemominutum' (SILVA et al, 2007). A total of 65 specimens (17.4%) belonging to nine different mammals (six rodents and three marsupials) were infected with hemotrophic mycoplasmas or Babesia sp.…”

Recent studies have been conducted in Brazil using molecular techniques for the detection of hemotrophic mycoplasmas in several mammals. In domestic cats, Mycoplasma haemofelis, 'Candidatus M. haemominutum', and 'Candidatus M. turicensis' infections have been identified. These species have also been found in free-ranging and captive neotropical felid species. Two canine hemoplasmas, Mycoplasma haemocanis and 'Candidatus Mycoplasma haematoparvum', have been identified in dogs. In commercial swine populations, Mycoplasma suis was found to be highly prevalent, especially in sows. Moreover, novel mycoplasma species have been identified in Brazilian commercial pigs and domestic dogs. A hemoplasma infection in a human patient infected with the human immunodeficiency virus (HIV) was also recently documented. In conclusion, hemoplasma species are common and important infectious agents in Brazil. Further studies should be conducted to better understand their impact on pets, production animals, and wildlife fauna, as well as their role as zoonotic agents, particularly in immunocompromised patients.Keywords: Hemoplasma, Mycoplasma haemofelis, Mycoplasma suis, HIV.

Em gatos domésticos, infecções por Mycoplasma haemofelis, 'Candidatus M. haemominutum' e 'Candidatus M. turicensis' foram identificadas. Estas espécies também foram encontradas em felídeos neotropicais de vida livre e de cativeiro. Dois hemoplasmas caninos, Mycoplasma haemocanis e 'Candidatus Mycoplasma haematoparvum', foram identificados em cães domésticos. Em populações comerciais de suínos, Mycoplasma suis possui alta prevalência, especialmente em porcas. Além disso, novas espécies de hemoplasmas foram detectadas em suínos comercias e cães. Infecção por um hemoplasma em um paciente humano infectado com o vírus da imunodeficiência humana (HIV) foi recentemente documentada. Em conclusão, espécies de hemoplasmas são comuns e importantes agentes de infecções no Brasil. Estudos futuros devem ser conduzidos para melhor entender seu impacto em cães e gatos, animais de produção e na fauna silvestre, e também para determinar o seu papel como agentes zoonóticos, particularmente em pacientes imunocomprometidos.Palavras-chave: Hemoplasma, Mycoplasma haemofelis, Mycoplasma suis, HIV.

“…While the worldwide rodent hemoplasma prevalence ranges from 11.1% in Japan [ 20 ] to 67.30% in Hungary [ 22 ], a similar occurrence, from 15% [ 29 ] to 63.5%, is observed in South America. The observed molecular occurrence of hemoplasma in rodents from Chile (24.5%) is similar to that previously reported in rodents from Brazil (21.9–25%) [ 15 , 28 ].…”

“…Rodents act as hosts for a variety of zoonotic pathogens [ 22 ] and several species of ticks and fleas [ 23 , 24 , 25 , 26 ]. Hemotrophic mycoplasmas in rodents have been reported in Brazil [ 14 , 15 , 27 , 28 , 29 , 30 ], Hungary [ 22 ], Japan [ 2 , 20 , 31 ], and Israel [ 32 ]. While Mycoplasma coccoides and M. haemomuris are the most commonly recognized hemoplasmas in the blood of wild and laboratory rodents, respectively [ 33 , 34 , 35 , 36 ], novel Mycoplasma spp., which has yet to to be fully characterized, have been described in rodents from Brazil [ 14 , 15 , 27 , 28 ] and Japan [ 20 ].…”

Molecular Survey and Genetic Diversity of Hemoplasmas in Rodents from Chile

Even though hemotrophic mycoplasma (hemoplasma) infections are well documented in a wide variety of hosts worldwide, there is a gap in the knowledge aobut hemoplasmas in rodents. This study aimed to molecularly survey and investigate the genetic diversity of hemoplasmas in rodents from Chile. Synanthropic and wild rodents (n = 74) were captured in the southern province of Valdivia (Corral, Valdivia, Riñihue, and Reumén localities). Spleen samples were submitted to a conventional PCR for hemotrophic Mycoplasma spp. targeting the 16S rRNA gene (800 bp), followed by sequencing, phylogenetic, and genetic diversity analyses. The overall occurrence of hemotrophic mycoplasmas in rodents from Valdivia was 24.5% (18/74) [95% CI (14.5; 34.1)]. Hemoplasmas were detected in Mus musculus (1/4), Rattus norvegicus (1/16), Abrothrix longipilis (7/13), A. olivaceo (6/8), and Oligoryzomys longicaudatus (3/10). The nucleotide polymorphism analysis of the targeted 16S rRNA region showed low diversity, with two genotypes and a high identity to the variants detected in wild rodents from Brazil. Hemoplasmas are described for the first time in rodents from Chile with a moderate occurrence and low 16S rDNA genetic diversity within the sampled rodent population. The detected hemoplasma genotypes were specific to rodents and were not shared with other mammals.
