Isolation and Identification of Bacteria Associated with the Screwworm FlyCochliomyia hominivorax,Coquerel and Its Myiasisa

Abstract

We studied eight different myiasis of sheep caused by screwworm flies under laboratory conditions. Swabs were taken from the wound, before, during, and after the myiasis. Seven hundred and thirty-one samples were streaked on different bacteriological media. All samples were identified by Api System (bioMerieuex). We found thirty-eight different bacterial species in the exudates from the myiasis (before, during, and after the parasitic cycle). The analysis of bacterial flora of the screwworm showed, on larvae stage 1, 10 different bacterial species, on larvae 2, 12 bacterial species; larvae 3, 15 bacterial species; crawl off, 15 bacteria species, pupa, 9 bacterial species; and adults, 2 bacterial species and on the pioneer fly, 14 different bacterial species were isolated and identified.

The Roles of Host Evolutionary Relationships (Genus: nasonia) and Development in Structuring Microbial Communities

“…An alternative function of Providencia could be that it plays a behavioral or olfactory role in locating fly hosts for Nasonia to parasitize. An example of this is the adult screwworm fly Cochliomyia hominivorax , which have a rich community of bacteria including several species of Providencia (Caballero et al 1996). These bacteria infect bovine wounds and provide a chemical cue for additional screwworm females to locate the wound and oviposit their eggs (Hammack et al 1987; Chaudhury et al 2002, 2010).…”

Bacteria isolated from 25 hydatid cysts in sheep, cattle and goats

“…In 1909, Mehlrose, cited by Dolfuss (1946), isolated Staphylococcus albus, Staphylococcus aureus, Staphylococcus citreus, Staphylococcus flavus, Micrococcus tetragenes, Sarcina lutea, Bacterium coli, Proteus vulgaris and Streptococcus brevis from some Cestoda, including Echinococcus polymorphus and Echinococcus multilocularis . Dolfuss (1946) and Caballero and others (1996) considered that the bacteria present on and within parasites were their normal microflora. Qualitative microbial findings have been recorded with respect to Ascaris lumbricoides (Nalin and McLaughlin 1976, Adedeji and Ogunba 1986), Dermanissus gallinae (Moro and others 2007), Dermatobia hominis (Sancho and others 1986, 1996), and Hsu and others (1986) found a high bacterial load in the gut of some specimens of Ascaris suum (average log 9·6 colony‐forming units/g).…”

Prevalência da microbiota no trato digestivo de fêmeas de Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae) provenientes do campo

“…Larvas de P. papatasi e L. longipalpis foram suscetíveis ao B.t.i., cuja toxicidade foi comprovada em adultos de P. papatasi, P. argentipes, P. perniciosus e L. longipalpis 3 33 . Espécies não identificadas de Staphylococcus (Gram-positivos) foram encontrado também em P. tobbi 29 e em mosca do gênero Cochliomyia 6 . Cocos Gram-positivos foram descritos no trato digestivo de P. papatasi em condições naturais 12 .…”
