  Diversity and antibiotic resistance profiles of bacteria isolated from the oral cavity of captive snakes Abstract Venomous snake bites are a global public health issue, causing between 81 000 and 138 000 annual deaths and 400 000 permanent disabilities. This study investigated the oral bacterial diversity and antibiotic resistance profiles in captive  Viperidae  snakes. Oral swabs from 48 specimens across four species ( Porthidium lansbergii ,  Bothriechis nigroviridis ,  Cerrophidion sasai , and  Bothrops asper ) were analyzed using culture-dependent methods. Bacterial isolation and identification using the VITEK 2 automated system revealed 41 strains from 12 genera, predominantly Gram-negative bacteria, including  Morganella morganii  (11 isolates) and  Providencia rettgeri  (10 isolates). Antibiotic susceptibility testing demonstrated significant resistance patterns, with 100% resistance to cephalothin and cefazolin i...

The identity of Heterothele caudicula (Araneae: Theraphosidae) from Argentina

Abstract


In this contribution, Heterothele caudicula Simon, 1886 (Theraphosidae) is transferred to the genus Thalerommata Ausserer, 1875. Thalerommata caudicula new combination is based on the examination of the type that is characterized by flattened iridescent setae covering the abdomen, a synapomorphy of this
genus. Thus, this is the ninth species of the genus known and Heterothele caudicula is removed from the Argentinean theraphosid fauna.
