Staphylococcus aureus is presently regarded as an emerging zoonotic agent due to the spread of specific methicillin-resistant S. aureus (MRSA) clones in pig farms. Studying the microbiota can be useful for the identification of bacteria that antagonize such opportunistic veterinary and zoonotic pathogen in animal carriers. The aim of this study was to determine whether the nasal microbiome of pig S. aureus carriers differs from that of non-carriers. The V3-V5 region of the 16S rRNA gene was sequenced from nasal swabs of 44 S. aureus carriers and 56 non-carriers using the 454 GS FLX titanium system. Carriers and non-carriers were selected on the basis of quantitative longitudinal data on S. aureus carriage in 600 pigs sampled at 20 Danish herds included in two previous studies in Denmark. Raw sequences were analysed with the BION meta package and the resulting abundance matrix was analysed using the DESeq2 package in R to identify operational taxonomic units (OTUs) with differential abundance between S. aureus carriers and non-carriers. Twenty OTUs were significantly associated to non-carriers, including species with known probiotic potential and antimicrobial effect such as lactic acid-producing isolates described among Leuconostoc spp. and some members of the Lachnospiraceae family, which is known for butyrate production. Further 5 OTUs were significantly associated to carriage, including known pathogenic bacteria such as Pasteurella multocida and Klebsiella spp. Our results show that the nasal microbiome of pigs that are not colonized with S. aureus harbours several species/taxa that are significantly less abundant in pig carriers, suggesting that the nasal microbiota may play a role in the individual predisposition to S. aureus nasal carriage in pigs. Further research is warranted to isolate these bacteria and assess their possible antagonistic effect on S. aureus for the pursuit of new strategies to control MRSA in pig farming.

“…Staphylococcus spp. are commonly isolated from various insect groups including whiteflies (Davidson et al, 2000;Yu et al, 2008;Ateyyat et al, 2010;Cakici et al, 2015;Pu & Hou, 2016). Ateyyat et al (2009) tested Staphylococcus gallinarum isolated from B. tabaci against the second instar nymphs of the pest through the leaf dipping method and reported that bacteria generated 19.5 and 28% infection after 3 and 5 d, respectively.…”

Whitefly, Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) hosting various bacteria is among the most significant insect pest causing economic losses in agricultural production. A study was conducted to determine the bacterial flora of B. tabaci and to identify the efficiency of these bacteria against B. tabaci. Samples were collected from sesame and melon plants in Mersin and Adana Provinces of Turkey in 2014. Nine bacterial strains were identified by morphological, MALDI-TOF MS and molecular identification methods to species level. Bacillus sp., Methylobacterium sp., Microbacterium sp., Serratia marcescens and Sphingomonas sp. were identified from the samples collected from sesame and Acinetobacter lwoffii, Bacillus cereus, Staphylococcus hominis and Staphylococcus warneri were identified from the samples collected from melon. To determine biological efficiency against B. tabaci adult (biotype B), whiteflies were fed with insect food as control (sucrose + water), insecticidal control (acetamiprid) and bacterial suspensions. The entomopathogenic bacteria S. marcescens isolated from B. tabaci for the first time in this study yielded an efficiency of 72% against adult whitefly. However, the other strains had efficiencies below 25%. It was concluded, given the efficiency of S. marcescens, that further research should be conducted on the pathology of entomopathogenic bacteria in pest insects.

The Hatay yellow strain silkworm (Bombyx mori L.), which is in danger of extinction, is one of the most important local cultural heritages of Türkiye. Bacterial pathogens of silkworm are highly destructive and cause mostly acute diseases. The aim of this study was to determine the bacterial diversity and potential pathogenic bacterial species in infected and dead larvae of Hatay yellow race. A total of 16 bacterial isolates from Hatay yellow race were identified according to their morphological, biochemical and molecular characteristics. The bacterial isolates isolated from infected and dead larvae of Hatay yellow race were Staphylococcus sp. (BM-1), Staphylococcus xylosus (BM-5), Staphylococcus succinus (BM-7), Bacillus thuringiensis (BM-8), Bacillus subtilis (BM-9), Bacillus sp. (BM-10), Staphylococcus saprophyticus (BM-16, BM-19), Klebsiella sp. (BM-17), Staphylococcus arlettae (BM-18), Pseudomonas aeruginosa (BM-20), Enterococcus mundtii (BM-21), Pantoea agglomerans (BM-22), Kluyvera intermedia (BM-23), Serratia sp. (BM-24), Mammaliicoccus sciuri (BM-25). The high bacterial density and number of species indicate that Hatay yellow race is highly susceptible to bacterial diseases. Insecticidal activity studies revealed that species belonging to Bacillus and Staphylococcus genera are important pathogens of hybrid silkworm culture and Hatay yellow race.
